BROWN NOISE (SMOOTHED)
I like listening to smoothed brown noise to drown out background noise and focus.
It was created in Reaper using RCNoiseBuzz by RCJacH.
EQ: -2db Low Shelf @ 139hz, -3db Band @ 438hz, and -5db High Shelf @ 1835hz (frequencies chosen by ear), reverb, and a limiter were applied as well.
Exported in OGG Vorbis @ 48kbps (44100, linear interpolation resampling).
