Here are some binaural beat audio files that I made in case anybody else wants to try them also. Please save them to your computer if possible.
http://snodart.com/snodpublic/BinauralBeats/ The name of the file represents the tone used and the difference in hertz.
Example:
100_3_8.mp3 is a 100 hertz tone in one ear and a 103.8 hertz tone in the other ear. The result of course is a 3.8 hertz binaural beat.
440_4_2.mp3 is a 440 hertz tone in one ear and a 444.2 hertz tone in the other ear, resulting in a 4.2 hertz binaural beat.
Each file contains a mix of the binaural beat tone, the sound of ocean waves, and a small amount of white noise. All audio fades in very slowly (and out), so you will need to go to the middle of the track to set an appropriate volume level.
At about 2 minutes into each track there is a single bass tone. I use this as a reminder to begin quieting my thoughts and to let go of any intelectual chatter.
At around 35 minutes into each track the binaural beat tones fade. At around 36 minutes, there are three bass tones followed by a simple song. These tones are to help bring me back to full waking consciousness. The short song is to give me a few moments to reorient myself.
Anyway, use them as you wish. I don't have enough spare time to custom mix anything new, but I can easily export different frequencies and beat ranges within this same audio mix and layout.
