Summary: Stumbled upon a little gem in the audio conversion for `SummaryWriter.add_audio()`: two Python `for` loops to convert a float array to little-endian int16 samples. On my machine, this took 35 seconds for a 30-second 22.05 kHz excerpt. The same can be done directly in numpy in 1.65 milliseconds. (No offense, I'm glad that the functionality was there!) Would also be ready to extend this to support stereo waveforms, or should this become a separate PR?
