Sanyo EP92H manual Sound Generator IC Midi, Audio Compression IC

*: 3D positioning function Function that can create a realistic impression of space even from cell phones that cannot provide an adequate speaker separation.

Sound Generator IC (MIDI)

SANYO has developed ICs that, in addition to support for even more sounds, also include new functions such as support for new standard melody formats and 3D audio.

Support for 24 hours of playback

Audio Compression IC

Although previous audio playback periods have been largely limited to 3 to 5 hours, it is now possible to achieve playing times of 24 hours or longer by adopting SANYO audio compression ICs.

Single-Chip Audio

LC82335X	Under
	development

The LC82335X ICs support MP3, AAC, and AAC+.

By implementing the MP3, AAC, and AAC+ decoding functions in a hardwired structure, these ICs achieve an ultralow power consumption that would be impossible in a DSP based structure.
