It’s been a while since I saw any topics on what to use to “slow down the speed” of an mp3 for transcribing. I’m wondering what’s out there now?

I’ve tried a couple of software programs, but the sound always ends up muddy. Windows Media Player has an adjustment to slow down playback, but that also gets muddy. Tascam has a hardware product called the “Instrumental Trainer/Recorder” which I’ve haven’t been able to hear.

Is anyone using either software or hardware and still getting a very clear sound when slowing the speed of a recording (for transcribing).

I think Audacity should do the trick and it's free.
