Sanyo EP92H - Manual (Page 11)

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. 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.

● Capable of generating up to 128-voice polyphony in a full PCM sound generator
128 GM sounds + 47 drum sets + 32 sound effects sounds (conforms to GM1)
● Includes a 3D surround function and a 3D positioning* function that allows the specification of positioning information
that positions the generated sound at an arbitrary position in three-dimensional space.
● Supports not only the Mobile XMF new melody format but also a variety of other formats
● User Customized Sound function that allows the user to register arbitrary sounds
● Supports up to four songs worth of MIDI data and can play up to four channels of ADPCM (PCM) data at the same time
● Includes a 4-band parametric equalizer that can provide optimal equalization for the speakers used
● Supports karaoke and Java applications: JSR135, JSR2348. Supports special effects such as pitch bend, vibrato, delay,
reverb, chorus, Doppler, and compression.

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.
● Hardwired MP3, hardwired AAC, and hardwired
AAC+.
● Ultralow power consumption: 10 mW
● Buffer size: 10 KB
● Built-in YY filter
● SD interface
