I like SBaGen for a binaural beat white noise generator. It’s pretty cool, and cross-platform, and lets you put other soundfiles in the background. (If you’re commandline-phobic and run Windows, I used to use Raindrop for the same reason.) But SBaGen is FAR more configurable, with all sorts of scriptable options.
Do I buy the brainwave stuff? Hell, I don’t know. But I do know that it’s a fantastic tool to help with concentration and block out outside noise and distraction. Give it (or Raindrop) a try while wearing headphones.
But. I started having problems when firing it up on my 64-bit Debian Jessie (#!) system… especially since the venerable padsp trick stopped working. I managed to get it working flawlessly again, but I’ve put this here for my own reference and to help anyone else dealing with this problem:
PulseAudio is the newer system of sound servers for linux, but some older programs try to write directly to sound devices the “old way”. Padsp is a wrapper script that lets the old programs use the new sound interface.
Until 64 bit systems came along, and the old programs wanted a 32-bit sound library. Then you get this error:
Copy libpulsedsp.so to /usr/lib32/libpulsedsp.so
Edit /usr/bin/padsp so that the line “while getopts” now reads:
Before the line starting with *), add these lines:
if [ x”$LD_PRELOAD” = x ] ; then
shift $(( $OPTIND – 1 ))
Now change your script to call padsp -i /path/to/sbagen
