Pulse Master slows down music without affecting pitch, so musicians can easier understand words, transcribe songs or transpose music key according to their needs.

Independent control of music speed and pitch is made in real-time by playing it from a CD, MP3, WAV, WMA, Ogg Vorbis file.

Besides some purely fun program implementations like:

• Morning coffee substitution with 30% faster song you found appropriate
• Having sex with your favorite song which loops and gradually increases its speed in background
• Prank with your friend's favorite singer or group you don't like so much
• Letting your kids play with "chipmunk" and "bear" voices

Pulse Master is also used seriously as flexible dictation machine, coreographers' and dancers' music speed adjusting tool, music teachers' didactic mean, singers' tool to change the music key to match their voice range or understand words in foreign languages.
