Title: "Binaural Beat Brain Wave Generation" and "Binaurals" MERGED
Post by: Greezael on July 24, 2010, 08:42:05 AM
Well, I've been using Rockbox for some time (thanks to God you finally managed to put it on the Nano 2G), and I think I've a good idea for it.

Some time ago, I discovered something called Binaural Beats. Perhaps you know them with the name of Digital Drugs, thanks to iDoser.com, although that's not their main function. They're sound which can alter the conscious state, very useful for meditation, astral projection, painkillers, and some weird and interesting stuff.

I write this because of Sbagen, which is a FREE binaural tones generator (not like that from idoser), which has been recently ported to Android.
http://www.normalesup.org/~george/comp/binaural_player/

Using the same modified code, the creator of the Android version told us that could be very easily developed in Rockbox. That would mean, as the doses can be more than half an hour long, using the standard .sbg files, which are only a few kilobytes big.

So, I would be very pleased to see my Rockbox player using my Binaurals, and so would most of the Sbagen community, i think.

The home of the project is http://uazu.net/sbagen/, and the programme itself runs on command line mode, so it would be just adapting a viewer for the files.




It would be a very interesting feature, which probably would help us to make Rockbox well known. I hope someone decide to do this little work (I just don't know how).

That source code has a lot of doubles in it, which means it'd have to be ported/rewritten to use integer math.  This is probably a lot of work.

What a pitty. Thanks anyway for your time.

Someday I will do it by myself! (I hope)

I would like this idea =P   I have heard of it from friends, and wondered what listening to it would be like ...It is a very cool idea indeed.

just came across SBaGen while looking into i-dosing; seems sbagen would make a killer app for rockbox.  :)

I don’t know about you, but I am (not) about to run out and experiment with the latest fad, known as “i-dosing,” a gimmick that supposedly uses binaural tones to create euphoria. “Simply put, i-dosing is the attempt to achieve a perceived drug ‘high’ from listening specially-engineered sounds and music,” reports Psychology Today.

Soap Edit:
Removed link because it was linked above and I'm a hair suspicious.

Gnaural is another GPL-licensed binaural beat generator:
http://gnaural.sourceforge.net/download/

It does seem to have a few floats and has some calls to calloc (just from a cursory glance), so it seems like this would be some work too.  I just wanted to provide this information in case someone decides they want to work on a binaural beat plugin.

Yeah but gnaural has small support.. And SBaGen is worth porting because I-Doser sound drugs use SBaGen format and this SBaGen data can be easily extracted to .sbg file, so when porting SBaGen, you port I-Doser (indirectly)

I had the same idea... I already use the iPod as (some sorto) of "mind machine" ... using soundfiles generated by Audacity...

but, the idea is to have the sound being generated (realtime, with parametric changes according to some script format) directly by the ¿sound engine? on the iPod (and maybe mixed realtime with some song?)

Could it be done with the library used for MIDI? (this is already in place and working)
just to use NOTES (with some instrument(or define a patch with sine wave)) instead of frecuency? as main parameter?
