You know, I thought about it but I am used to transcribing with a foot pedal to start and stop and trying to do it on an MP3 file won't work with my software so you have to stop and start manually and if you need to go back you have to scrub and I was having a hard time getting close to the time stops. I got about 3 minutes transcribed and I had to take a break.
if someone knows how I could do it with better control I would consider giving it a try.
