I'm impressed with the sound quality. Great little utility. I was unsatisfied with the sound quality of the open source utilities I'd found.

MP3 Speed Changer enables you to speed up audio files (MP3, WMA and many others) – podcasts, audiobooks without changing the pitch. Batch processing feature and easy-to-use user interface make MP3 Speed Changer valuable tool for audio listeners and authors who want to save time.

You can speed up your audio in a few moments, just select the files you want to speed up and choose the new tempo. Files will be automatically speeded up and converted to MP3 so you can move them right to your portable MP3 player or open in your favorite software MP3 player.

You can also save time with video. MP3 Speed Changer enables you to extract the audio track from video file, speed it up and save as MP3.

At the 150% tempo you save 20 minutes for every hour of audio material you listen to. Your mind can easily handle the faster tempo, since you can think far faster than anyone can naturally talk.

I had an audio-book that was too slow and with MP3 Speed Changer, I've changed its tempo to 139 and it's normal speed. Great!
