VS1063 MP3 Encoder and Audio Codec Chip

VLSI Solution introduced the VS1063 audio codec chip. The VS1063 can encode many audio formats: MP3 and Ogg Vorbis to G.711 u-law, G.711 A-law, G.722 and 16-bit PCM. The MP3 and Ogg Vorbis encoders are optimized for the highest possible audio fidelity for high-quality audio streaming or recording. The VS1063 audio codec chip can play back MP2, MP3, WMA, OGG, LC-AAC, HC-AAC, FLAC, IMA, G.711 u-law, G.711 a-law, G.722 and WAV PCM formats. Samples of the VS1063 IC will available in June 2011. Mass production of the devices are expected to begin in September 2011.
