Changing Tempo with SoX

You will recall that Sox stands for "Sound eXchange," and it is
"the Swiss Army knife of audio manipulation." Changing tempo means
changing the length of a sound clip without speeding it or slowing
it down. This is useful for when a specific word count must fit
into set amount of time, such a radio spot or training slide. In
this episode, we'll explore the command line options to get the
results you and your clients need.
