Epson will be showing off its latest audio decoder chip, the S1V30220, at 3GSM in Barcelona. Through support for MPEG-4 AACPlus version 2 (Enhanced AACPlus) this chip can turn any mobile phone into an ace music player.
The S1V30220 is a single chip solution and supports AACPlus, AAC, MP3 and MIDI content. It also handles post-processing functions such as loudspeaker equalisation, digital volume control and stereo to mono down mix.
This chip also offers an MMC/SD Card interface and FAT file system, allowing for stand-alone audio decoding without the need for a host processor. A complete PC-based development/evaluation kit is available.
The actual donkey work for the incorporation of AACPlus into the S1V30220 was done by a Swedish company, Coding Technologies, which is typical of the kind of small company exhibiting at 3GSM 2006.
