I need to add a really short (1 1/2 seconds) of feedback noise to a scene - does anyone know how this can be achieved in Audition or does anyone know where I can get a wav clip of some feedback?
OK. No one has jumped in with a real answer...so...
Got a mic hooked up to your soundcard in the computer? Turn on a recorder (something on-board that will record a .wav) and bring the mic close to one of the speakers. You should get some howling feedback that way. Be careful not to overload the recorder or the sound will be clipped.
