I was able to convert base64 string directly to wav : import base64 encode_string = base64.b64encode (open ("audio.wav", "rb").read ()) wav_file = open ("temp.wav", "wb") decode_string = base64.b64decode (encode_string) wav_file.write (decode_string) First encode it into base64. Then create a file in wav format and write the decoded base64 Python convert wav to mp3. 0. Playing audio through audio tag in a Django application. 25. Python convert mp3 to wav with Pydub. 1. How to map an audio file with librosa.output.write_wav¶ librosa.output.write_wav (path, y, sr, norm=False) [source] ¶ Output a time series as a .wav file. Note: only mono or stereo, floating-point data is supported. For more advanced and flexible output options, refer to soundfile.

Here's an example that worked for me. If you put the recorded audio into a speech_recognition AudioData object, there are methods available for converting to various audio formats (e.g., get_wav_data(), get_aiff_data(), get_flac_data(), etc.). See here: speech_recognition AudioData

2. When you write. subprocess.call ("sox" + filename + "-c 1 -r 16000" + new_filename, shell=True) what's actually going to be executed for an exemplary TEST.WAV file looks like this: soxTEST.WAV-c 1 -r 16000converted_TEST.WAV. So you're missing the spaces in between. A nice solution using Python's f-strings ( Formatted string literals) would trIYT.
