Binaural sounds also known as LFA or low frequency audio (V5.3+)

In the main GUI

Binaural sounds are sounds that are perceived within the mind when listening to combinations of sound frequencies. The effects range from feeling alert through to very relaxed depending on the combination of frequencies being played. Binaural sounds are also often known as "low frequency audio" or "mind sync audio".

Panning and smooth start do not apply to to Binaural sounds and the volume is set at whatever the system volume is. It is therefore important to ensure that the system volume is set as low as possible before playing Binaural sounds. A slider to control the system volume has been provided (Windows 2000+).

To play a Binaural sound click on the "Wave" icon, select a file and click on OK. To stop playing a Binaural sound click on the round "Stop" icon. There are many sample files provided.
