Arduino WaveHC Library

Newer! Better! Sparklier! Download the WaveHC library by clicking here

For information how to use and install libraries, see our tutorial! Then check out the examples for how to use it.

This library pretty much requires a '328 Arduino, see our upgrade tutorial if you have a '168 Arduino.

Download the latest library here (currently: Feb 18, 2008 which now supports the 328P and arduino v13 under mac and windows & probably linux).

Before you try to play audio, you'll want to free up some Arduino RAM, so that you don't end up with a nasty stack-overflow. Follow these instructions on how to get more RAM by reducing the input Serial library buffer.

The library is based off of Roland Riegel's AVR FAT16 code, but pared down quite a bit to reduce flash and RAM usage. There are also some strange optimizations to make it play audio better.

Demo waves

If you need some audio to test with, here is a synthesized voice saying "Hello world."

Here is the collection of numbers for the pispeak example!
