    Hi, does anyone know of a way to save audioclip data (captured via the microphone) into something other than wav using Unity? Like ogg or mp3?

    Hi!
    your question seems to imply that you have figured out how to save audioclip data to wav?

    Unity will give you the raw samples from the microphone. There are quite a few libraries that will translate that to various formats.

    There are also a few voice chat packages on the asset store. They usually use the very fast u-law or similar, which produce good performance and acceptable quality for voice, but isn't recommended for music and similar.

    Hi,

    A while back, I shared a writing to wav script here.

    Not tested in 4.0 beta, and written while I was even less experienced than I am now, but it certainly works in 3.5+.

    Wow, that's nice. Did you find a way to convert to ogg as well? So far I've been using the oggenc unix executable, but I'd prefer a c# solution.
