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).
