Available now at the app store.
I produced all custom sounds for App Camelots’ Deep Relax and is now one of their most successful apps. I wanted to design audio that is non intrusive to the listener especially on headphones and could be listened to for hours. In order to design smooth and soothing audio we had to design sounds that where harmonious to the ear, sounds that where not overly repetitive and jarring. A lot of the sounds where created from my personal field recordings I have built up over the years.

The app is great in that it can be customized by mixing together multiple sounds and saved as your own template. It also contains binaural beats with three different alpha stages.


Binaural beats have been widely studied in cognitive and neurological research and are said to influence functions of the brain in ways besides those related to hearing. A variety of states of consciousness are said to be induced as well as, decreased anxiety, help people memorise and learn, stop smoking, help dieting, tackle erectile dysfunction, improve athletic performance, recovery of repressed memories, create the effect of recreational drugs, and in this case help to relax and enhance meditative focus.

Using headphones, two coherent sounds of nearly similar frequencies are presented to each ear. The brain integrates the two signals, producing a sensation of a third sound, sub-frequency pulsations called the binaural beat.

The effect on the brain depends on the difference in frequencies of each tone: for example, if 200 Hz was played in one ear and 210 in the other, then the binaural beat would have a frequency of 10 Hz.

Perceived human hearing is limited to the range of frequencies from 20 Hz to 20,000 Hz, but the frequencies of human brain waves are below about 40 Hz.

When the perceived beat frequency corresponds to the delta, theta, alpha,beta, or gamma range of brainwave frequencies, the brainwaves move towards the beat frequency.

Beta (13-26 Hz) Alert concentration and problem-solving
Alpha (8-13 Hz) Alert relaxation
Theta (4-7 Hz) Deep relaxation and increased learning
Delta (1-3 Hz) Deep sleep
