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 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 to devs:AHI/ 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.
