I'm looking a prosumer audio editing application that works with macs. I'm looking to edit out some of the umms and ahhs out of an hour long interview that i have. I can't afford Pro Tools but I don't want to use quicktime pro. I'm looking for a basic program that I can cut out audio from the waveform. So far I have found Bias Peak but I'm not sure if this is the program that would be good for me. Anyone have any ideas?
