that addresses several sound quality issues. In addition,
an updated 14 Bit Calibration utility is provided.


Release Notes

- 4.33
  - stereo 14 Bit calibration support enabled
- 4.32
  - more appropriate default parameters for uncalibrated systems
  - rewrote negative amplitude part of calibration table algorithm 
    to avoid quantization artifacts at low amplitudes
  - Included revised Paula Calibration utility that is aware of the
    slightly changed calibration semantics
  - see around the label _CreateTable in paula.a for
    some technical discussion

Installation
¯¯¯¯¯¯¯¯¯¯¯¯
Make sure you have AHI installed properly before proceeding.

Copy paula.audio from this archive`s DEVS/AHI/ directory to 
"DEVS:AHI/" to replace the existing file.

You may need a reboot.

If you should insist on using 14 Bit AHI on 68000/68010, please 
copy paula.audio.000 to devs:AHI/paula.audio instead of the
default 68020 binary.

The 14 Bit Calibration utility can be copied anywhere. It does
not require a special installation procedure. Please follow the
guidelines given when starting the program. The updated utility
can perform stereo calibration, which is enabled as of the 4.33
release of this AHI driver. Some presets for typical OCS Paula 
(8364R7) and ECS Paula (8364R7PD,8364R7PL) chips can be selected 
by the menu strip as respective starting points, if desired.


Licenses
¯¯¯¯¯¯¯¯
AHI version 6 is (L)GPL:ed. See COPYING and COPYING.LIB inside the
archive for more information.

The Calibration utility is (c) Christian Buchner. The original can
be found in the 14Bit_CDPlayer archive on Aminet. Modifications done
by Henryk Richter. The code was placed into public domain.
