The company, VLSI solutions offers many ICs with the ability to both decode and encode MP3 files, as well as audio in many other formats. A few of their ICs are compared below VS1011 The VS1011 is a basic MP3 and WAV decoder. It offers the following features: Decodes MP3 and WAV files; Up to 320 kbps MP3 quality; Streaming support for MP3 and WAV; Operates from 2.3V to 3.6V; High quality DAC converter; 5.5 KiB RAM on chip for user code; Low operation; Bass and treble controls; Serial control and data interfaces; 4 GPIO pins Costs ~$20 VS1063 The VS1063 is a more advanced audio codec. It offers the following features: Encodes (in mono or stereo) at 8-48 kHz the following formats: MP3; Ogg Vorbis; 16-bit PCM; IMA ADPCM; G.711 u-law and A-law; G.722 ADPCM; Decodes the following formats at up to 48 kHz: MP3; MP2; Ogg Vorbis; MPEG4 / 2 AAC-LC(+PNS), HE-AAC v2 (Level 3) (SBR + PS); WMA4.0/4.1/7/8/9 all profiles (5-384 kbps); FLAC lossless audio (up to 24 bits); WAV: 16-bit PCM, IMA G.711 u-law and A-law, G.722 ADPCM; Streaming support; Upto 96 KiB RAM for user code and data; Unique ID for code protection; I2S interface for external DAC; High-quality stereo A/D converter; Serial control and data interfaces; Can be used either as a co-processor or as a standalone processor; UART for debugging purposes; New functions may be added with software and 12 GPIO pins; Ear Speaker Spatial Processing;
