If you’re on a pc, check out this suite of audio utilities, including a conversion utility that will transcode between most audio formats. It’s one of the few that handles FLAC, SHN and Monkeys Audio. Until I found this I was using a host of small utilities to handle the live music I am always grabbing, it’s a huge time saver. Plus the portable audio tool is great if you’re using a portable MP3 player but don’t like the software that’s needed to move music onto the device (but check to see if your device is compatible first). All of it is free to try, some of it requires licensing in the $20 range after 30 days.
