8-channel PCM/ADPCM sample-based sound chip designed for use with arcade machines. It lived throughout mid to late 90s. It has 16-level stereo panning, up to 16-bit PCM and up to 16MB of external PCM data. 4-bit ADPCM has a sample playback rate limit of 44.1 kHz with a tuning resolution of 256 Hz, while 8-bit and 16-bit PCM can go up to 88.2kHz with a tuning resolution of 512 Hz.

Effects

None so far.

Info

4-bit ADPCM format can be selected in the sample editor as “YMZ/YMU ADPCM”. For this format, loop start and end points must align to multiples of 2 samples, and samples will be padded to a multiple of 2 samples. PCM samples have a maximum playback rate of the chip’s clock divided by 192.

Chip Configuration

The following options are available in the Chip Manager window:
  • Clock rate: Sets the rate at which the chip will run.
