I’ve been doing interviews over a speaker telephone using both an iphone and a mp3 recorder / player to record. I’ve done 8 so far and three of them (all to the same person) have been murky and almost impossible to hear. The recording of my own voice is clear but that’s not of any use to me. Is there a way I can enhance his voice so that I can transcribe what he’s saying? I’ve been playing around a bit with noise reduction but I’m trying to finish my thesis and don’t have time to try and learn software. Can anyone help? Thanks. Manda.
