When listening to recordings of human speech (like audio books, conference recordings, ...) it can be useful to have the ability to adjust the playback speed without changing the pitch of the recording. This simple command line program can do this for you. Playing a audio book at 150% of its original tempo is still intelligable and saves time, therefore the name of the program.

Currently the following audio encoding formats are supported:

• Ogg Vorbis
• Ogg Speex
• MPEG
