The VS1053b + VS1000 HiFi Recorder is an example of a product that can be built by using the VS1053b multi-codec chip and the VS1000 controller IC. It is one of the most versatile "MP3 players" around: it can play back music in MP3, AAC, WMA, Ogg Vorbis, FLAC, MIDI and ADPCM formats. It can also record either in high-quality Ogg Vorbis or lossless PCM formats. Its measured dynamic range is better than 90 dB. The VS1000 controller application is available in binary format, and source code will be made available later so that the board can be customized for different applications.
