Install SoX and you can generate noise without using any data at all. Even without internet access. Imagine that.

  play -n synth 60:00 whitenoise
  play -n synth 60:00 pinknoise
  play -n synth 60:00 brownnoise

Or make your own wav files:

  sox -n whitenoise.wav synth 60:00 whitenoise
  # Also works with pinknoise/brownnoise

I wouldn't use lossy compression to compress these. There's no redundant data in noise so lossy compression will just make it less noise-y. I can only imagine that noise on streaming services sounds weird.
