Turn back time? Yes! Intermission lets you pause and rewind live audio
on your computer. Streaming audio will never be the same!

With Intermission, you can jump back and replay something you missed,
then resume live playback. Use it to pause any audio while you take a
call, answer the door, or use the restroom. You can even pause
streaming audio on services like Pandora, iTunes Radio, or Spotify to
build a buffer, then skip right past the ads and songs you don't want
to hear!
