pyaudioconvert
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
Requirements
- At least py3x
- Have sox installed
Install
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
