I'm having the same problem. I found this command on a random site[1] which improves it a bit: play -n -n --combine merge synth '24:00:00' brownnoise band -n 750 750 tremolo 50 1 If possible I'd like to replicate the brown noise preset used on this[2] site. If you come up with anything please let us know. [1] https://www.cloudacm.com/?p=3145 [2] https://mynoise.net/NoiseMachines/whiteNoiseGenerator.php
I've settled on this over the years: play -c 2 --null synth brownnoise reverb bass 6 treble -3 It's close to the myNoise brown preset, IMO, if a little bass heavier.
play -c 2 --null synth brownnoise reverb bass 10 treble -6
Diagnosed around 40, concerta helps with focus but does not provide a calming effect.
Thanks for this eye opener!
`Brew install sox` for those wondering how to get this working on macos.
