 NAME 
       lame - create mp3 audio files

 SYNOPSIS 
       lame [options] <infile> <outfile>

 DESCRIPTION 
       LAME  is  a program which can be used to create compressed
       audio files.  (Lame ain't an MP3  encoder).   These  audio
       files  can  be  played back by popular MP3 players such as
       mpg123 or madplay.   To  read  from  stdin,  use  "-"  for
       <infile>.  To write to stdout, use a "-" for <outfile>.

 OPTIONS 
       Input options:

       -r     Assume  the  input  file is raw pcm.  Sampling rate
              and mono/stereo/jstereo must be  specified  on  the
              command  line.   Without -r, LAME will perform sev-
              eral fseek()'s on the input file  looking  for  WAV
              and AIFF headers.
              Might not be available on your release.

       -x     Swap  bytes  in  the input file or output file when
              using --decode. 
              For sorting out little endian/big endian type prob-
              lems.   If  your  encodings sounds like static, try
              this first.

       -s sfreq 
              sfreq = 8/11.025/12/16/22.05/24/32/44.1/48

              Required only for raw PCM input  files.   Otherwise
              it  will be determined from the header of the input
              file.

              LAME will automatically resample the input file  to
              one  of the supported MP3 samplerates if necessary.

       --bitwidth n 
              Input bit width.
              n = 8, 16, 24, 32 (default 16)

              Required only for raw PCM input  files.   Otherwise
              it  will be determined from the header of the input
              file.

       --mp1input 
              Assume the input file is a MPEG Layer I file.
              If the filename ends in ".mp1" or ".mpg" LAME  will
              assume  it  is  a  MPEG Layer I file.  For stdin or
              Layer I files which do not end in .mp1 or .mpg  you
              need to use this switch.

       --mp2input 
              Assume  the  input file is a MPEG Layer II (ie MP2)
              file.
              If the filename ends in ".mp2" LAME will assume  it
              is  a  MPEG  Layer  II file.  For stdin or Layer II
              files which do not end in .mp2 you need to use this
              switch.

       --mp3input 
              Assume the input file is a MP3 file.
              Usefull  for  downsampling from one mp3 to another.
              As an example, it  can  be  usefull  for  streaming
              through an IceCast server.
              If  the filename ends in ".mp3" LAME will assume it
              is an MP3.  For stdin or MP3 files which do not end
              in .mp3 you need to use this switch.

       --nogap file1 file2 ... 
              gapless encoding for a set of contiguous files

       --nogapout dir 
              output  dir  for  gapless  encoding  (must  precede
              --nogap)

       Operational options:

       -m mode 
              mode = s, j, f, d, m

              Joint-stereo is the default mode for  stereo  files
              with  VBR  when -V is more than 4 or fixed bitrates
              of 160kbs or less.  At  higher  fixed  bitrates  or
              higher VBR settings, the default is stereo.

              (s)tereo 
              In  this  mode,  the encoder makes no use of poten-
              tially existing correlations between the two  input
              channels.   It  can,  however,  negotiate  the  bit
              demand between both channel, i.e. give one  channel
              more  bits  if  the other contains silence or needs
              less bits because of a lower complexity.

              (j)oint stereo 
              In this mode, the encoder will make use of a corre-
              lation  between  both channels.  The signal will be
              matrixed into a sum ("mid"), computed by  L+R,  and
              difference  ("side")  signal,  computed by L-R, and
              more bits are allocated to the mid  channel.   This
              will effectively increase the bandwidth if the sig-
              nal does not have too much stereo separation,  thus
              giving a significant gain in encoding quality.

              Using mid/side stereo inappropriately can result in

                         October 13, 2001                       2


              audible compression artifacts.  To  much  switching
              between  mid/side and regular stereo can also sound
              bad.  To  determine  when  to  switch  to  mid/side
              stereo,  LAME  uses a much more sophisticated algo-
              rithm than that described in the ISO documentation,
              and thus is safe to use in joint stereo mode.

              (f)orced joint stereo 
              This mode will force MS joint stereo on all frames.
              It is slightly faster than  joint  stereo,  but  it
              should  be  used  only  if  you are sure that every
              frame of the input file has very little stereo sep-
              aration.

              (d)ual channels 
              In this mode, the 2 channels will be totally inden-
              pendently encoded.  Each channel will have  exactly
              half  of  the  bitrate.   This mode is designed for
              applications  like  dual  languages  encoding  (for
              example:  English  in one channel and French in the
              other).   Using  this  encoding  mode  for  regular
              stereo  files will result in a lower quality encod-
              ing.

              (mo)no 
              The input will be encoded as a mono signal.  If  it
              was  a  stereo  signal,  it  will be downsampled to
              mono.  The downmix is calculated as the sum of  the
              left and right channel, attenuated by 6 dB.

       -a     Mix  the  stereo  input  file to mono and encode as
              mono.
              The downmix is calculated as the sum  of  the  left
              and right channel, attenuated by 6 dB.

              This  option  is only needed in the case of raw PCM
              stereo input (because  LAME  cannot  determine  the
              number of channels in the input file).  To encode a
              stereo PCM input file as mono, use lame -m s -a. 

              For WAV and AIFF input files, using -m  -I  m  will
              always  produce a mono .mp3 file from both mono and
              stereo input.

       -d     Allows the left and right channels to use different
              block size types.

       --freeformat 
              Produces   a  free  format  bitstream.   With  this
              option, you can use -b with any bitrate higher than
              8 kbps.

              However, even if an mp3 decoder is required to sup-
              port free bitrates at least up to  320  kbps,  many

              players are unable to deal with it.

              Tests  have  shown that the following decoders sup-
              port free format:
              FreeAmp up to 440 kbps
              in_mpg123 up to 560 kbps
              l3dec up to 310 kbps
              LAME up to 560 kbps
              MAD up to 640 kbps

       --decode 
              Uses LAME for decoding to a wav  file.   The  input
              file  can  be any input type supported by encoding,
              including layer I,II,III (MP3) and OGG  files.   In
              case of MPEG files, LAME uses a bugfixed version of
              mpglib for decoding.

              If -t is used (disable wav header), LAME will  out-
              put  raw  pcm in native endian format.  You can use
              -x to swap bytes order.

       -t     Disable writing of the INFO Tag on encoding.
              This tag in embedded in frame 0 of  the  MP3  file.
              It  includes  some  information  about the encoding
              options of the file, and in VBR it lets  VBR  aware
              players correctly seek and compute playing times of
              VBR files.

              When --decode is specified (decode  to  WAV),  this
              flag  will  disable writing of the WAV header.  The
              output will be raw pcm, native endian format.   Use
              -x to swap bytes.

       --comp arg 
              Instead  of  choosing  bitrate,  using this option,
              user can choose compression ratio to achieve.

       --scale n 
       --scale-l n 
       --scale-r n 
              Scales input (every channel, only left  channel  or
              only right channel) by n.  This just multiplies the
              PCM data (after it has been converted  to  floating
              point) by n. 

              n > 1: increase volume
              n = 1: no effect
              n < 1: reduce volume

              Use  with  care, since most MP3 decoders will trun-
              cate data which  decodes  to  values  greater  than
              32768.

       --preset  [fast] type | [cbr] kbps 
              Use one of the built-in presets.

              Have a look at the PRESETS section below.

              Warning:  with  the  current  version  fast presets
              might result in too high bitrate compared to  regu-
              lar presets.

              --preset  help  gives more infos about the the used
              options in these presets.

       --alt-preset  [fast] type | [cbr] kbps 
              Use one of the built-in  presets.

              This option is deprecated and offers  the  same  as
              the  --preset  option above. Do not use it anymore,
              it will go away in a later version.

       --r3mix 
              Uses r3mix VBR preset.
              See http://www.r3mix.net/ for more details.

       --noasm  type 
              Disable specific assembly  optimizations  (  mmx  /
              3dnow  /  sse  ).   Quality will not increase, only
              speed will be reduced.  If you have  problems  run-
              ning  Lame  on a Cyrix/Via processor, disabling mmx
              optimizations might solve your problem.

       Verbosity:

       --disptime n 
              Set  the  delay  in  seconds  between  two  display
              updates.

       --nohist 
              By  default,  LAME will display a bitrate histogram
              while producing VBR mp3 files.  This  will  disable
              that feature.
              Histogram  display  might  not be available on your
              release.

       -S 
       --silent 
       --quiet 
              Do not print anything on the screen.

       --verbose 
              Print a lot of information on the screen.

       --help Display a list of available options.

       Noise shaping & psycho acoustic algorithms:

       -q qual 
              0 <= qual <= 9

              Bitrate is of course the main influence on quality.
              The  higher  the  bitrate,  the higher the quality.
              But for a given bitrate, we have a choice of  algo-
              rithms to determine the best scalefactors and huff-
              man encoding (noise shaping).

              -q 0: 
              use slowest & best possible version  of  all  algo-
              rithms.  -q 0 and -q 1 are slow and may not produce
              significantly higher quality.

              -q 2: 
              recommended.  Same as -h. 

              -q 5: 
              default value.  Good speed, reasonable quality.

              -q 7: 
              same as -f.  Very fast, ok quality.  Psycho  acous-
              tics  are  used  for  pre-echo  & M/S, but no noise
              shaping is done.

              -q 9: 
              disables almost all algorithms including psy-model.
              Poor quality.

       -h     Use  some  quality  improvements.  Encoding will be
              slower, but the result will be of  higher  quality.
              The behaviour is the same as the -q 2 switch.
              This switch is always enabled when using VBR.

       -f     This  switch  forces  the  encoder  to use a faster
              encoding mode,  but  with  a  lower  quality.   The
              behaviour is the same as the -q 7 switch.

              Noise  shaping  will be disabled, but psycho acous-
              tics will still be computed for bit allocation  and
              pre-echo detection.

       CBR (constant bitrate, the default) options:

       -b n   For  MPEG1 (sampling frequencies of 32, 44.1 and 48
              kHz)
              n = 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192,
              224, 256, 320

              For MPEG2 (sampling frequencies of 16, 22.05 and 24
              kHz)

                         October 13, 2001                       6


              n = 8, 16, 24, 32, 40, 48, 56,  64,  80,  96,  112,
              128, 144, 160

              Default is 128 for MPEG1 and 64 for MPEG2.

       --cbr  enforce use of constant bitrate

       ABR (average bitrate) options:

       --abr n 
              Turns  on  encoding with a targeted average bitrate
              of n kbits, allowing to  use  frames  of  different
              sizes.   The allowed range of n is 8 - 310, you can
              use any integer value within that range.

              It can be combined with  the  -b  and  -B  switches
              like: lame --abr 123 -b 64 -B 192 a.wav a.mp3 which
              would limit the allowed frame sizes between 64  and
              192 kbits.

              The  use  of -B is NOT RECOMMENDED.  A 128 kbps CBR
              bitstream, because of the bit reservoir, can  actu-
              ally  have  frames  which use as many bits as a 320
              kbps frame.  VBR modes minimize the use of the  bit
              reservoir,  and  thus need to allow 320 kbps frames
              to get the same flexibility as CBR streams.

       VBR (variable bitrate) options:

       -v     use variable bitrate (--vbr-old) 

       --vbr-old 
              Invokes the oldest, most tested VBR algorithm.   It
              produces  very  good  quality  files, though is not
              very fast.  This has, up through v3.89,  been  con-
              sidered the "workhorse" VBR algorithm.

       --vbr-new 
              Invokes  the  newest  VBR  algorithm.   During  the
              development of version  3.90,  considerable  tuning
              was  done  on this algorithm, and it is now consid-
              ered to be on par with the original --vbr-old.   It
              has  the  added  advantage of being very fast (over
              twice as fast as --vbr-old). 

       -V n   0 <= n <= 9
              Enable VBR (Variable  BitRate)  and  specifies  the
              value  of  VBR  quality (default = 4).  0 = highest
              quality.

       ABR and VBR options:

              Specifies the minimum bitrate to be used.  However,
              in  order to avoid wasted space, the smallest frame
              size available will be used during silences.

       -B bitrate 
              For MPEG1 (sampling frequencies of 32, 44.1 and  48
              kHz)
              n = 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192,
              224, 256, 320

              For MPEG2 (sampling frequencies of 16, 22.05 and 24
              kHz)
              n  =  8,  16,  24, 32, 40, 48, 56, 64, 80, 96, 112,
              128, 144, 160

              Specifies the maximum allowed bitrate.

              Note: If you own an mp3 hardware player build  upon
              a MAS 3503 chip, you must set maximum bitrate to no
              more than 224 kpbs.

       -F     Strictly enforce the -b option.
              This is mainly for use with hardware  players  that
              do not support low bitrate mp3.

              Without  this  option,  the minimum bitrate will be
              ignored for passages of analog silence,  i.e.  when
              the  music level is below the absolute threshold of
              human hearing (ATH).

       ATH related:

       --noath 
              Disable any use of the ATH (absolute  threshold  of
              hearing)  for masking.  Normally, humans are unable
              to hear any sound below this threshold.

       --athshort 
              Ignore psychoacoustic model for short  blocks,  use
              ATH only.

       --athonly 
              This option causes LAME to ignore the output of the
              psy-model and only use masking from the ATH  (abso-
              lute  threshold  of  hearing).   Might be useful at
              very high bitrates or for testing the ATH.

       --athtype shape 
              The Absolute Threshold of Hearing  is  the  minimum
              threshold under which humans are unable to hear any
              sound.
              In the past, LAME was using ATH shape  0  which  is
              the  Painter  &  Spanias formula.  Tests have shown
              that this formula is innacurate for the 13 - 22 kHz
              area, leading to audible artifacts in some cases.
              Shape  1 was thus implemented, which is over sensi-
              tive, leading to very high bitrates.
              Shape 2 formula was accurately modelized from  real
              data  in  order  to reach optimal quality while not
              wasting bitrate.  In CBR and ABR modes,  LAME  uses
              ATH  shape  2 by default, VBR selects one depending
              on the specified parameter to the -V option.

       --athlower n 
              Lower the ATH (absolute threshold of hearing) by  n 
              dB.
              Normally, humans are unable to hear any sound below
              this threshold, but for music recorded at very  low
              level this option might be usefull.

       --athaa-type n 
              ATH auto adjust types 1 - 3, else no adjustment

       --athaa-sensitivity x 
              activation offset in -/+ dB for ATH auto-adjustment

       PSY related:

       --short 
              Let LAME use short blocks when appropriate.  It  is
              the default setting.

       --noshort 
              Encode  all  frames  using  long blocks only.  This
              could increase quality when encoding  at  very  low
              bitrates,  but  can  produce serious pre-echo arte-
              facts.

       --allshort 
              Use only short blocks, no long ones.

       --cwlimit freq 
              Compute tonality up to freq (in kHz).  Default set-
              ting is 8.8717.

       Experimantal options:

       -X n   0 <= n <= 7

              When LAME searches for a  "good"  quantization,  it
              has  to  compare  the  actual one with the best one
              found so far.  The comparison  says  which  one  is
              better,  the  best  so  far  or the actual.  The -X 
              parameter selects between different  approaches  to
              make this decision, -X0 beeing the default mode:

              -X0 
              The criterions are (in order of importance):
              * less distorted scalefactor bands
              * the sum of noise over the thresholds is lower
              * the total noise is lower

              -X1 
              The  actual is better if the maximum noise over all
              scalefactor bands is less than the best so far.

              -X2 
              The actual is better if the total sum of  noise  is
              lower than the best so far.

              -X3 

                         October 13, 2001                      10


              The  actual  is better if the total sum of noise is
              lower than the best so far and  the  maximum  noise
              over all scalefactor bands is less than the best so
              far plus 2dB.

              -X4 
              Not yet documented.

              -X5 
              The criterions are (in order of importance):
              * the sum of noise over the thresholds is lower
              * the total sum of noise is lower

              -X6 
              The criterions are (in order of importance):
              * the sum of noise over the thresholds is lower
              * the maximum noise over all scalefactor  bands  is
              lower
              * the total sum of noise is lower

              -X7 
              The criterions are:
              * less distorted scalefactor bands
              or
              * the sum of noise over the thresholds is lower

       -Y     lets LAME ignore noise in sfb21, like in CBR

       -Z     toggles the scalefac feature on

       MP3 header/stream options:

       -e emp emp = n, 5, c

              n = (none, default)
              5 = 0/15 microseconds
              c = citt j.17

              All  this  does is set a flag in the bitstream.  If
              you have a PCM input file where one  of  the  above
              types  of (obsolete) emphasis has been applied, you
              can set this flag in LAME.  Then  the  mp3  decoder
              should  de-emphasize  the  output  during playback,
              although most decoders ignore this flag.

              A better solution would be to apply the de-emphasis
              with a standalone utility before encoding, and then
              encode without -e. 

       -c     Mark the encoded file as being copyrighted.

       -o     Mark the encoded file as being a copy.

       -p     Turn on CRC error protection.
              It will add a cyclic redundancy check (CRC) code in
              each  frame, allowing to detect transmission errors
              that could occur on the MP3  stream.   However,  it
              takes  16  bits  per  frame that would otherwise be
              used for encoding, and then  will  slightly  reduce
              the sound quality.

       --nores 
              Disable  the  bit  reservoir.  Each frame will then
              become independent  from  previous  ones,  but  the
              quality will be lower.

       --strictly-enforce-ISO 
              With  this  option,  LAME will enforce the 7680 bit
              limitation on total frame size.
              This results in many wasted bits for  high  bitrate
              encodings but will ensure strict ISO compatibility.
              This compatibility might be important for  hardware
              players.

       Filter options:

       -k     Tells the encoder to use full bandwidth and to dis-
              able all filters.  By  default,  the  encoder  uses
              some  highpass  filtering at low bitrates, in order
              to keep a good quality by giving more bits to  more
              important frequencies.
              Increasing  the  bandwidth from the default setting
              might produce ringing artefacts  at  low  bitrates.
              Use with care!

       --lowpass freq 
              Set a lowpass filtering frequency in kHz.  Frequen-
              cies above the specified one will be cutoff.

       --lowpass-width freq 
              Set the width of the lowpass filter.   The  default
              value is 15% of the lowpass frequency.

       --highpass freq 
              Set  an  highpass filtering frequency in kHz.  Fre-
              quencies below the specified one will be cutoff.

       --highpass-width freq 
              Set the width of the highpass filter in  kHz.   The
              default value is 15% of the highpass frequency.

       --resample sfreq 
              sfreq = 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48
              Select  ouptut  sampling  frequency (only supported
              for encoding).
              If not specified, LAME will automatically  resample

 ID3 TAGS 
       LAME  is  able to embed ID3 v1, v1.1 or v2 tags inside the
       encoded MP3 file.  This allows to have some usefull infor-
       mation  about  the  music  track included inside the file.
       Those data can be read by most MP3 players.

       Lame will smartly choose wich tags to use.   It  will  add
       ID3  v2 tags only if the input comments won't fit in v1 or
       v1.1 tags, i.e. if they are more than 30  characters.   In
       this  case,  both  v1 and v2 tags will be added, to ensure
       reading of tags by MP3 players wich are unable to read ID3
       v2 tags.

 ENCODING MODES 
       LAME  is  able  to  encode  your  music using one of its 3
       encoding modes: constant bitrate  (CBR),  average  bitrate
       (ABR) and variable bitrate (VBR).

       Constant Bitrate (CBR) 
              This  is  the  default  encoding mode, and also the
              most basic.  In this mode, the bitrate will be  the
              same  for  the whole file.  It means that each part
              of your mp3 file will be using the same  number  of
              bits.   The  musical passage beeing a difficult one
              to encode or an easy one, the encoder will use  the
              same  bitrate,  so the quality of your mp3 is vari-
              able.  Complex parts will be  of  a  lower  quality
              than  the easiest ones.  The main advantage is that
              the final files size won't change and can be  accu-
              rately predicted.

       Average Bitrate (ABR) 
              In  this mode, you choose the encoder will maintain
              an average bitrate while using higher bitrates  for
              the  parts  of your music that need more bits.  The
              result will be of higher quality than CBR  encoding
              but  the average file size will remain predictible,
              so this mode is highly recommended over CBR.   This
              encoding mode is similar to what is reffered as vbr
              in AAC or Liquid Audio (2 other  compression  tech-
              nologies).

       Variable bitrate (VBR) 
              In  this  mode, you choose the desired quality on a
              scale from 9 (lowest quality/biggest distortion) to
              0   (highest   quality/lowest   distortion).   Then
              encoder tries to maintain the given quality in  the
              whole  file  by choosing the optimal number of bits
              to spend for each part of  your  music.   The  main
              advantage is that you are able to specify the qual-
              ity level that you want to reach, but the  inconve-
              nient is that the final file size is totally unpre-
              dictible.

 PRESETS 
       The --preset switches are designed to provide the  highest
       possible quality.

       They  have for the most part been subject to and tuned via
       rigorous  double  blind  listening  tests  to  verify  and
       achieve this objective.

       These  are continually updated to coincide with the latest
       developments that occur and as a result should provide you
       with nearly the best quality currently possible from LAME.

       To activate these prests:

       For VBR modes (generally highest quality):

       --preset standard 
              This preset should generally be transparent to most
              people  on  most music and is already quite high in
              quality.

       --preset extreme 
              If you have  extremely  good  hearing  and  similar
              equipment,   this  preset  will  generally  provide
              slightly higher quality than the standard mode.

       For CBR 320kbps (highest quality possible from the  --pre- 
       set switches):

       --preset insane 
              This  preset will usually be overkill for most peo-
              ple and most situations, but if you must  have  the
              absolute  highest  quality  with no regard to file-
              size, this is the way to go.

       For ABR modes (high quality per given bitrate but  not  as
       high as VBR):

       --preset  kbps 
              Using  this preset will usually give you good qual-
              ity at  a  specified  bitrate.   Depending  on  the
              bitrate  entered,  this  preset  will determine the
              optimal settings  for  that  particular  situation.
              While  this  approach  works,  it  is not nearly as
              flexible as VBR, and usually will  not  attain  the
              same level of quality as VBR at higher bitrates.

       The  following  options  are also available for the corre-
       sponding profiles:

       fast standard|extreme|insane 
       cbr  kbps 

                         October 13, 2001                      15


       fast   Enables the new fast VBR for a particular  profile.
              The  disadvantage to the speed switch is that often
              times the bitrate will be slightly higher than with
              the  normal  mode and quality may be slightly lower
              also.

       cbr    If you use the ABR mode (read above) with a signif-
              icant  bitrate  such as 80, 96, 112, 128, 160, 192,
              224, 256, 320, you can use the cbr option to  force
              CBR mode encoding instead of the standard ABR mode.
              ABR does provide higher quality but CBR may be use-
              ful  in  situations  such  as when streaming an MP3
              over the internet may be important.

 EXAMPLES 
       Fixed bit rate jstereo 128kbs encoding:

              lame sample.wav sample.mp3 

       Fixed bit rate jstereo 128 kbps encoding, highest  quality
       (recommended):

              lame -h sample.wav sample.mp3 

       Fixed bit rate jstereo 112 kbps encoding:

              lame -b 112 sample.wav sample.mp3 

       To  disable  joint  stereo  encoding (slightly faster, but
       less quality at bitrates <= 128 kbps):

              lame -m s sample.wav sample.mp3 

       Fast encode, low quality (no psycho-acoustics):

              lame -f sample.wav sample.mp3 

       Variable bitrate (use -V n to adjust quality/filesize):

              lame -h -V 6 sample.wav sample.mp3 

       Streaming mono 22.05 kHz raw pcm, 24 kbps output:

              cat inputfile | lame -r -m m -b 24 -s 22.05 -  -  > 
              output 

                         October 13, 2001                      16


       Streaming  mono  44.1  kHz  raw  pcm, with downsampling to
       22.05 kHz:

              cat inputfile | lame -r -m m -b 24 --resample 22.05 
              - - > output 

       Encode with the fast standard preset:

              lame --preset fast standard sample.wav sample.mp3 

 BUGS 
       Probably there are some.
