FUNCTIONAL DESCRIPTION

Voice Synthesis Algorithms

The ML2302 supports five PCM algorithms to process various kinds of voices.

1. 4-bit OKIADPCM algorithm

2. 4/5/6/7/8-bit OKIADPCM2 algorithm

3. 2-bit OKIADPCM algorithm

4. 8/16-bit straight PCM algorithm

5. 8-bit OKI Non-linear PCM algorithm

Voice Synthesis Algorithms and Sampling Frequencies during Recording and Playback

The relationships between the voice synthesis algorithms and sampling frequencies available during recording and

playback are shown in Tables 1.1.1 and 1.1.2.
