GNAural was created in 1998 by Dr. Larry Lohm of the Stanford Neuropsychology Laboratory. GNAural allows you to build complex musical compositions by superimposing several different recordings, each called a "voice." Each voice is a binaural beat, isochonic pulse, pink sound, isochronic wave, or any other custom sound file. The frequency of the sounds can be adjusted by adjusting "frequency data points" on four levels. Once the frequencies are all combined in a "basket," each voice is mixed with the next and so on until the whole recording is combined into a single piece.
To create the music, each of the voices is "trained" by playing a complex mathematical equation. In simple terms, it's similar to playing a piano but you don't have to learn music theory. In the music recording industry, GNAural beats are often used in conjunction with other types of digital audio processing. The audio files are processed using a series of digital filters and then are played back in a different order using an audio server (PC) such as the Linux-based PCA Music Server. The final output is then transferred to a CD. Audio streaming is becoming a popular method to transfer GNAural beats to a computer through the Internet.
Free GNAural beats are available for download through an online website. You may need to search for these manually, though, because each free GNAural file is usually only available in its entirety in one format (MP3). This can result in some of the beats being mislabeled as being available for free, if the file you want isn't available as a WAV file. There are also instances when files that are available as free downloads are made available with limited rights, making it more difficult for others to modify them. If you want to download free GNAural beats, you may have to try several online sources to locate them. This can take time and frustration, but the effort will be worth it in the end. once you finally have a free download available for you to use.
