VOICE SECTION COMBINATIONS
aP8921A/10
Voice files created base developing system stored built-in EPROM aP8921A/10A chip number fixed length Voice Blocks. Voice Blocks then selected grouped into Voice Groups playback. Voice Groups allowed. Voice Block Table used store information combinations Voice Blocks then group them together form Voice Group. Chip Memory size Voice Block bytes Voice Block Max. Voice Group Voice Table entries Voice Length 6KHz 4-bit ADPCM) aP8921A 512K bits aP8910A 256K bits
Example Voice Block Combination Assume here have three voice files, they "How You?", Sound Effect Music. Each voice file divided into number fixed length Voice Block stored into memory. Voice File "How You?" stored Voice Block B12. Voice File Sound Effect stored Voice Block B15. Voice File Music Voice Block B40. Voice Blocks grouped together using Voice Table form Voice Group playback: Group Group Group Group Group Voice Group contents "How You?" Sound Effect "How You?" "How You?" Music Music Voice Table Entries
Voice Data Compression
Voice File data stored on-chip EPROM either 4-bit ADPCM 8-bit format. Voice data stored 4-bit ADPCM provides data compression which save memory space. other hand, voice data stored 8-bit format means data compression employed voice playback quality will better.

both Trigger Mode Parallel Trigger Mode, user select different trigger functions output signals sent from pins OUT1 OUT2. Options affect Voice Group playback called Whole Chip Options. Options only affect playback individual Voice Group called Group Options. Whole Chip Options Parallel Trigger Mode. Ramp-up-down enable disable: When COUT used playback, Ramp-up-down should enabled. This function
eliminates `POP' noise beginning voice playback. When VOUT1 VOUT2 used drive speaker directly, Ramp-up-down should disabled.
