How to efficiently convert a Flask FileStorage object to a format Whisper API accepts?

API
1

I have a simple Flask endpoint for transcribing audio that a user sends:

@app.route('/transcribe', methods=['POST'])
def endpoint_transcribe():
   if 'audio' not in request.files:
      return jsonify({"error": "No audio file provided"}), 400
      
   audio_file = request.files['audio']
   try:
      # save a temporary instance of the file to satisfy the API
      audio_file.seek(0)
      temp_path = "./temp_audio.webm"
      audio_file.save(temp_path)
      with open(temp_path, "rb") as file:
         transcription = client.audio.transcriptions.create(
            model="whisper-1",
            file=file
         )
      # clean up
      os.remove(temp_path)
      
      return jsonify(transcript=transcription.text)
   except Exception as e:
      print(e)
      return jsonify({"error": str(e)}), 500

This works fine, but I’m writing and reading the file to disk each time a user makes a request. Is there a better way?

I have not tested it yet but others seem to have made it working:

Not quite what I’m looking for. I’m not using a buffer.
