.BWG File Extension

Audio file used by BrainWave Generator (BWG), a program that uses sound and visual stimulation to try and help users relax, meditate, and focus better; saves audio in the form of a "binaural beat," which attempts to change brain frequencies toward a desired state.

BWG files can be converted to .WAV files using BrainWave Generator. Open your binaural beat, choose Wave → Play Into WAV File..., and then choose your output location.

NOTE: The BWG software was last updated in 2005.
