A small package to convert audio files

Project description


Simple utility to convert audio from one form to another (via sox). We will use Sox until we find a fast and efficient way to convert reliably in python


  1. At least py3x
  2. Have sox installed


  1. pip install pyaudioconvert

Example Usage

Converting Single WAVs

#let's start with a 24bit 48kz audio wav 2 channel wav
>>> soxi example_24bit_48k_2ch.wav 

Input File     : 'example_24bit_48k_2ch.wav'
Channels       : 2
Sample Rate    : 48000
Precision      : 24-bit
Sample Encoding: 24-bit Signed Integer PCM

#we prefer 16-bit 16kz mono for our systems, let's use python
>>> import pyaudioconvert as pac
>>> pac.convert_wav_to_16bit_mono('example_24bit_48k_2ch.wav', 'example_16bit_16k_1ch.wav')
Out[2]: 'example_16bit_16k_1ch.wav'

#let's check the new file...
>>> soxi example_16bit_16k_1ch.wav 

Input File     : 'example_16bit_16k_1ch.wav'
Channels       : 1
Sample Rate    : 16000
Precision      : 16-bit
Sample Encoding: 16-bit Signed Integer PCM

Converting Directory of WAVs

Maybe I have a whole folder of WAVS that need converting... this will create a _16k.wav version.

(py36) rob:~/example_test$ ls
1.wav  2.wav  3.wav  4.wav
