wav-to-pcm

This contains python scripts for converting wav files to pcm data for further processing.

Requirements

• pyaudio
• wave

Usage

First record audio using 'audio_record.py' --> This will output a 'output.wav' file

Now if you run 'check-output1.py' it will print out..

• Number of frames

• Array containing all the frames

• Rate of the Frame capture : 44100

• Total Time recorded : 5

(Both can be changed in 'audio_record.py')

• Bit length of each Frame : 16

If you just want to use array of pcm data, Just include pcm_channels.py in your code and call "pcm_channels" by passing the name of the audio output file.

Function "pcm_channels" will return a tupple containing [pcm_data, sample_rate]
