Is it really necessary to use pink noise (the static-like sound) with the binaural beats?
It is recommended (by The Monroe Institute, etc) to mix binaural beats at a low level with some kind of background sound, e.g. pink noise. This is why pink noise is provided in sbagen. However, a better alternative would be to mix in some other kind of soundtrack. From version 1.4.0, SBaGen supports randomly-loopable OGG files, and two files of river sounds are provided. These can be mixed in using the -m option (e.g. -m river1.ogg). You can also create your own background soundtracks as MP3 or OGG files.
