What is returned by scipy.io.wavefile.read()?
wavfile.read() returns two things:
data: This is the data from your wav file which is the amplitude of the audio taken at even intervals of time.
sample rate: How many of those intervals make up one second of audio.
I have never worked with audio before.
For a monophonic wav file read() returns an 1-D array of integers. What do these integers represent? Are they the frequencies? If not how do I use them to get the frequencies?
