    Nice...but this is better, (Arduino in Propeller forum?)

    Next up ... auto-tune and getting Elton John to sing falsetto again.

    .. looking for a voice changer made with a Propeller chip...

    Any examples of Open Stomp with a human voice input instead of guitar?

    It might sound impressive, but this stuff is really easy to do. It can be done in a single cog with much better sample rate than 40 kHz! (40 kHz might be impressive for an Arduino)
    I remember doing this in realtime at 50 kHz on a bog standard 7.14 MHz Amiga. (fun times)
    It's basically a ring buffer, one write pointer and one read pointer. By "manipulating" the read pointer in different ways, all kinds of weird effects can be achieved.

    A search for example code regarding ring buffers with write and read pointers didn't turn up anything. Is there any sample propeller code that can be used as a starting point? I found this object that samples the mic and plays it back on the headphones. http://obex.parallax.com/objects/57/

    hi, some time ago, I posted FunnyVoice. Done with PropBasic to get the speed. It is a lot of fun, to play with sound.

    The object "microphone_to_headphones.spin" in the Propeller Tool's "_Demos" folder can alter a human voice a little by using a slow sample rate.

    Here's a thread that's got some audio modification stuff in it:
