I ripped a mixcloud stream using a great free MediaHuman app (Youtube to Mp3). I now need to rip the desired 6 minute song (in m4a format) from a 2 hour stream. The trouble is: I can't seem to find a decent app to do it.

I tried using a couple of online apps but the file was too large to upload, and I can't seem to find a decent app to use for my iMac anymore.

Do you know of an easy-to-use and/or free music trimmer/cutter app?

thanks
