Repacer

Convert the pace of any music and create mixes that exactly fit your natural workout pace. Select the music you want and enter the pace you prefer, and the newly paced file is ready for your next workout. It supports the conversion of music from CDs (it includes CDDB support) and audio files (MP3, OGG, WMA, WAV, AIFF, AU). The program also features a customizable activity list so you can set different paces for different workouts. Clear documentation is included.

Version 1.5 adds support for reading and writing MP3 files and the ability to preview a repaced track before saving.
