Manipulating (almost) Live Radio Streams?

    Sep 27 2013 | 12:44 pm
    I'm trying some things out for a potential installation piece. I want the audience to be able to interact with a live radio broadcast but I want to incorporate time stretching and playback position randomisation so using actual live audio is out of the question.
    I was thinking that a way around this would be to record the audio to an .aiff and then having it load into a buffer a minute or 5 minutes after the live broadcast. Is continually updating an audio file without interrupting the sound possible? I can't work it out.
    I realise that I could save myself a lot of trouble by just recording an hour of radio and using that, but using actual live broadcasts would be such much more satisfying
