Voice Synthesis Algorithm
Four types of voice synthesis algorithm are supported. They are OKI 4-bit ADPCM2, OKI 8-bit non-linear PCM,
8-bit straight PCM and 16-bit straight PCM. Select the best one according to the characteristics of playback
voice.
The following table shows key features of each algorithm.
