Please see my previous post on installing software and stretching audio up to a billion times. Summary below.

PaulStretch 101

Easy how to on music track stretching

• Download and install PaulStretch-2.0 software, it runs on MacOSX, Windows and Linux (via WINE).
• Run the application and choose a track via File > Open
• Click play, wait and listen.
• [Optional] Hit the “Write to file” tab and then click “Render selection…”. Choose your filename and output format (Ogg/MP3/WAV).

If you want to show off your new rendering of Chitty Chitty Bang Bang slowed down a million times, or whatever music you’re into, then SoundCloud is as good a place as any to share it.

This was my first effort to stretch a music track following the howto of that post and using Audacity to truncate it.
