The VS1053b + VS1000 HiFi Recorder is a multi-format media player and recorder device that can play almost any audio files and record with several qualities from mono wideband speech at 49 kbit/s to stereo linear HiFi PCM at 1.5 Mbit/s. A clear OLED display offers playback and recording information as well as a menu system.

The idea behind the player is for it to act as a reference design for an "MP3 player" and high quality recording device. To help with customization, the full source code for the VS1000 controller application will be made available for free use to anyone wishing to modify the device.


The software binary is available. 


For new projects that require OggVorbis or MP3 encoding, we recommend either VS1063 or VS1005 device.
