CouldntDecodeError: Decoding failed. ffmpeg returned error code: 1

[udita1903]

I have about 3000 audio files all of whose extensions were changed to .wav.
I tried using pydub to load the audio file using 'from_file' and 'from_file_using_temporary_files` but it hasn't worked so far

This is the error that it keeps throwing

CouldntDecodeError Traceback (most recent call last)
Cell In[8], line 2
1 # sound = AudioSegment.from_file(src)
----> 2 sound = AudioSegment.from_file_using_temporary_files(src)
3 sound.export(dst, format="wav")

623 if p.returncode != 0:

625 "Decoding failed. ffmpeg returned error code: {0}\n\nOutput from ffmpeg/avlib:\n\n{1}".format(
626 p.returncode, p_err.decode(errors='ignore') ))
627 obj = cls._from_safe_wav(output)
628 finally:
