White noise
I found a site that has free mp3’s of whitenoise. Download one, then in the shell
mplayer -loop 0 foo.mp3
That will loop over and over forever.
The only problem so far is when the file starts over there is some silence. That is distracting, however I am going to see if I can edit the file tonite, Or at least find a longer one.
Pink Noise > White Noise
This is the best pink noise generator.
That said, that mp3 doesn’t cost anything, so yeah. ;)
This is probably because of MP3’s internal block structure. If you can find the originals (wav or some other PCM) that don’t have a gap on the end you can use –nogap with lame to produce a better file.
Or use Ogg ;)
