AudioFileSourceBuffer is an input source that simpy adds an additional RAM buffer of the output of any other AudioFileSource. This is particularly useful for web streaming where you need to have 1-2 packets in memory to ensure hiccup-free playback. ...

[MrRedBeard] wanted to play a particular song from an Arduino program and got tired of trying to hand transcribe the notes. A little research turned up that there was a project to convert Music XML (MXL) files to the Arduino. However, [MrRedBeard] wasn’t a fan of the language it use...

I loveMIDI Controllers! They are some of the coolest yet most powerful devices for controlling mixed media - traditionally used to connect to music software (likeAbleton Live) to play virtual instruments as well as control effects - but can also be used with VJ software (likeResolume), and ...
Here is a shield for Arduino 328's that solves this problem. It can play up to 22KHz 12bit uncompressed audio files of any length. It's low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of ...
