Convert ogg audio to wav in python without ffmpeg

Question

I am getting oga file from javascript blob and I want to convert it to PCM compatible wav file in python. The approach I am using is as follow

AudioSegment.converter = r"C:/ffmpeg/bin/ffmpeg.exe"
AudioSegment.ffprobe   = r"C:/ffmpeg/bin/ffprobe.exe"
sound = AudioSegment.from_file("file.oga")
sound.export("file.wav", format="wav")

For this I have to download ffmpeg locally. Is there any way to convert oga file to wave directly.

This is how i am saving file

f = open('./file.oga', 'wb')
f.write(base64.b64decode(file))
f.close()

Answer 1

Try this:

import os
import soundfile as sf  # pip install pysoundfile

input_folder = 'ogg_files_folder'
output_folder = 'wav_files_folder'

if not os.path.exists(output_folder):
    os.makedirs(output_folder)

for filename in os.listdir(input_folder):
    if filename.endswith('.ogg'):
        input_file_path = os.path.join(input_folder, filename)
        
        data, samplerate = sf.read(input_file_path)
        
        output_file_path = os.path.join(output_folder, os.path.splitext(filename)[0] + '.wav')
        
        sf.write(output_file_path, data, samplerate)
        
        print(f'Converted {input_file_path} to {output_file_path}')

print('Conversion complete.')
