This is the second day of my participation in Gwen Challenge

When dealing with audio formats, you need to download various audio processing software (there are fees for professional software). Those of us who know Python know that Python can do everything (ha ha ha, just kidding). Audio format lossless conversion in Python

Pydub supports conversion between audio formats. The demo looks like this (only 3 formats are shown here, and various common audio formats are described below) :

01 Install the PyDub library

Install the Python library -Pydub with the following command

pip install pydub

Copy the code

Once installed, introduce PyDub into Python

from pydub import AudioSegment


Copy the code

02 This section describes common audio formats

Here are some common audio formats, each with its own characteristics. Let’s start converting between audio formats programmatically.

1. Mp3 -> WAV, OGG, flag, etc

from pydub import AudioSegment
    
# transform function method
   
def trans_mp3_to_wav(filepath,hz) :
    
song = AudioSegment.from_mp3(filepath)
    
song.export("Python researcher."+str(hz), format=str(hz))
    
Parameter 1: audio path, parameter 2: converted format
    
trans_mp3_to_wav("Light music.mp3"."wav")
    
trans_mp3_to_wav("Light music.mp3"."ogg")
    
trans_mp3_to_wav("Light music.mp3"."flac")

Copy the code

Transformation results:

Convert light music. Mp3 to WAV, OGG, FLAC, and name it Python Researcher. After the conversion are lossless high tone quality, without any distortion.

Wav, OGG, FLAC ->mp3

song = AudioSegment.from_wav("Python researcher. Wav.")
   
song.export("Python researcher _wav-mp3.mp3".format="mp3")
    
song = AudioSegment.from_ogg("Python researcher. Ogg")
    
song.export("Python researcher _ogg-mp3.mp3".format="mp3")
    
AudioSegment.from_file("Python researcher. Flac")
    
song.export("Python researcher _flac-mp3.mp3".format="mp3")

Copy the code

‍

After testing, WAV, OGG and FLAC can also be successfully converted to MP3, proving that direct conversion between different audio formats is possible.

03 summary

Here is only a demonstration of MP3, FLAC, WAV, OGG these four formats, the rest of the other formats we can start to try, here is not repetitive repetitive.
