Adjusting audio parameters

During your exploratory data analysis, you may find some of the parameters of your audio files differ or are incompatible with speech recognition APIs.

Don't worry, PyDub has built-in functionality which allows you to change various attributes.

For example, you can set the frame rate of your audio file calling set_frame_rate() on your AudioSegment instance and passing it an integer of the desired frame rate measured in Hertz.

In this exercise, we'll practice altering some audio attributes.
