Voice Synthesis Algorithm
Four types of voice synthesis algorithm are supported. They are 4-bit ADPCM2, 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.
