Audio, Video processing
Audio signal processing, sometimes referred to as audio processing, is the processing of a representation of auditory signals, or sound. The representation can be digital or analog. An analog representation is usually electrical; a voltage level represents the air pressure waveform of the sound. Similarly, a digital representation expresses the pressure wave-form as a sequence of symbols, usually binary numbers.

Yet Another Time Machine
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 based on the SoundTouch library 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.
