Wonderful concept. I've been using a conceptually similar program, FasterAudio, for going on two years. I *love* being able to listen to AudioBook Summaries at between 200 and 230 percent.
BUT . . . I'm beginning to formulate a theory about these programs.There seems to be a particular speed at which their sped-up versions become garbled. For FasterAudio, that tipping point is at 200 percent. Everything sounds pretty normal (just very fast!) up to 200 percent. At 201 percent, one starts to hear some pretty significant sonic distortion, weird "echo"-y background noises, and clippy/choppy sound. As indicated above, even with the best quality original, I can't make out what the speaker is saying above about 230 percent; the distortion is just too great.
I have been looking for something to do a better job than FasterAudio.
MP3 Speed Changer isn't it. At least not at its present state of development (7/25/09). Its tipping point seems to be somewhere in the mid-100s percent--perhaps at 150, where the creators have it pre-set at startup. I didn't waste my time trying to figure out exactly where its sound goes to pieces. I "just" did some quick testing and realized 200% was useless, and 160% was really bad. Even with an untrained "ear," I BEGAN my compressions at 180% on FasterAudio.

Sorry.
Clarity suffers on FasterAudio
