How to convert Telegram voice in a wave file in python

问题:

I'm trying to save a Telegram voice file in a wave audio file using soundfile library:

def ReceiveVoice(bot, update, user_data):     voice = bot.getFile(update.message.voice.file_id)    voice.download('file.ogg')    data, samplerate = sf.read('file.ogg')    sf.write('file.wav', data, samplerate) 

But I'm receiving the following error:

File "C:\Python27\lib\site-packages\soundfile.py", line 257, in read subtype, endian, format, closefd) as f: File "C:\Python27\lib\site-packages\soundfile.py", line 624, in __init__ self._file = self._open(file, mode_int, closefd) File "C:\Python27\lib\site-packages\soundfile.py", line 1179, in _open "Error opening {0!r}: ".format(self.name)) File "C:\Python27\lib\site-packages\soundfile.py", line 1352, in _error_check raise RuntimeError(prefix + _ffi.string(err_str).decode('utf-8', 'replace')) RuntimeError: Error opening 'file.ogg': File contains data in an unimplemented format. 

回答1:

You could try to use ffmpeg to convert from ogg to wav by executing the following command line using python's module subprocess.

import subprocess src_filename = 'captured.ogg' dest_filename = 'output.wav'  process = subprocess.run(['ffmpeg', '-i', src_filename, dest_filename]) if process.returncode != 0:     raise Exception("Something went wrong") 

回答2:

Try this

import soundfile as sf data, samplerate = sf.read(input_ogg) sf.write(output_wav, data, samplerate)
