title: Joining .wav files without writing on disk in Python
body: <p>I have a list of .wav files in binary format (they are coming from a websocket), which I want to join in a single binary .wav file to then do speech recognition with it. I have been able to make it work with the following code:</p>
  
  <pre><code>audio = [binary_wav1, binary_wav2,..., binary_wavN] # a list of .wav binary files coming from a socket
  audio = [io.BytesIO(x) for x in audio]
  
  # Join wav files
  with wave.open('/tmp/input.wav', 'wb') as temp_input:
      params_set = False
      for audio_file in audio:
          with wave.open(audio_file, 'rb') as w:
              if not params_set:
                  temp_input.setparams(w.getparams())
                  params_set = True
              temp_input.writeframes(w.readframes(w.getnframes()))
  
  # Do speech recognition
  binary_audio = open('/tmp/input.wav', 'rb').read())
  ASR(binary_audio)
  </code></pre>
  
  <p>The problem is that I don't want to write the file <code>'/tmp/input.wav'</code> in disk. Is there any way to do it without writing any file in the disk?</p>
  
  <p>Thanks.</p>
