Binaural player is an Android application to generate binaural beats <URL: http://en.wikipedia.org/wiki/Binaural_beats >.
It was mostly written by Nicolas George nicolas.george@normalesup.org.
It is based on SBaGen <URL: http://uazu.net/sbagen/ > by Jim Peters.

Start the application, select the file in the list, put the headphones and click on play.
Android interface
At this time, I am quite recent to Android development. Therefore,
expect a few glitches.SBaGen porting
SBaGen is originally a standalone program, which is not usable in an
Android application. It was necessary to turn it into a library, with
specific entry points. Most of the work was to replace turn the calls to
exit into a correct error-reporting scheme and remove memory leaks.
To make this work manageable, a lot of features had to be removed. This
version does not support mixing of input files, and only accepts simple
sequence files in start-to-end (-SE) mode.
This version of sbagen.c can probably be useful for applications in
other embedded contexts.Build and Makefile
This project does not use the official Android build system and
directory layout. It rather uses a simple Makefile (with GNU
extensions). It can be used as an example on how to build an Android
application step by step.
