Project Helios
Specification
Sound CHIP
- This subproject tries to design an enhanced-PSG AY-3-8192 (family : 8190, 8192 & 8193).
The AY-3-8912 is a 3 channels sound generator that it produces simple tones (square waves) and
more complex sound by using an envelope generator.
- Here is the specification about ePSG8192 :
-
- stereo, 3 voices, seven octave, white noise generator, envelope generator,
- and/or FM operator,
- 8 voices ADCPM stereo(8/16 bits).
- 8 echantillons, 8 or 16 bits width,
- 0 ... 44100 Hz,
- It can applies many effect on.
