    Am playing around with a bit of a personal assistant app, that includes letting people record smallish audio notes/sound clips, etc., and am currently using pyAudio to handle recording - relatively simple/easy, etc., but, one small issue seems to be that if I use something like winsound to beep just before start recording, to sort of notify user that recording is about to start, this seems to possibly cause input/output stream issues.

    In other words, possible to avoid/work around, but, just wondering what guys would recommend looking into for simple little bits of audio recording of sound clips, etc.?

    TIA
