I'm working with audio files in a Jupyter notebook, loading/processing with Librosa and playing audio back with IPython.display. I can use np.multiply(audio_file, 0.25) to change the amplitude of the audio array, but IPython.display's Audio plays it back at exactly the same volume regardless. The following also does not work to change the playback volume:
audio_file_softer = audio_file * 0.25
Audio(audio_file_softer, rate=sr)
It seems pyaudio no longer works with Python. How can I alter the volume of the playback audio? Any better libraries for playing back audio from within a Jupyter notebook?
