Thanks Grumpy_Mike & jackrae.

I think I'll look into the MIDI option.

Hello,

I'd like to submit a project that I recently completed.

This project uses a laser pointer and a couple of motors with attached mirrors to display patterns (lissajous figures) that are in sync with music. The audio data is processed by a Python script that extracts frequency information, converts that to motor pulses and send it to the Arduino (clone) via the serial interface.

I have a complete write-up here, which also has a video:

3  Using Arduino / Project Guidance / Playback of multiple sounds (wav files) simultaneously using Arduino on: December 05, 2012, 09:23:04 pm
I would like to play multiple pre-recorded audio samples (up to 5 wav files) simultaneously. These are in response to some sensors can be are triggered independently.

So the files can start and stop playing at any time - the output should be a mix of all these sounds.

What is a good approach for playback of multiple sounds simultaneously using Arduino? Do I need external hardware?

I was also considering generating MIDI. I don't know much about it - is it possible to create a MIDI file with multiple channels of data which keep changing?

Thanks & Regards
