VS1053 is a single-chip MP3/AAC/WMA/MIDI audio decoder and ADPCM encoder. It contains a high-performance, proprietary low-power DSP processor core VS_DSP4, working data memory, 5 KiB instruction RAM and 0.5 KiB data RAM for user applications, serial control and input data interfaces, upto 8 general purpose I/O pins, an UART, as well as a high-quality variable-sample-rate mono ADC and stereo DAC, followed by an earphone amplifier and a common buffer.
VS1053 features special Headphone Sound Externalization feature (EarSpeaker) that processes the decoded audio to provide more natural sound in headphone listening conditions. It widens the stereo image and positions the sound sources outside the listener's head.
