Binaural Beats Dataset

This dataset lists tracks along with their metadata for the binaural beats for the five brainwaves. It is not exhaustive, but should be complete enough for most use cases, since it contains binaural beats mixed with isochronic pulses and solfeggios as well. You can use this dataset by downloading a release. Every track is from the YouTube channel FulLengthBinaurals because they have allowed the tracks to be redistributed in any way.

Documentation

Since system controls cannot manipulate browser audio playback unless it has a duration of at least five seconds, every track is at least five seconds long. Pure and isochronic tracks can be set to loop because even if they start in the middle of a sine wave, they end in the same position (which is why tracks with non-integral frequencies have durations ten times their frequencies). Solfeggio tracks can't loop because they are'nt monotonous.

The tracks directory contains the binaural beats in MP3 format. Solfeggio tracks are fifteen minutes long. Pure and isochronic tracks are at least five seconds long. The following conventions are used to name tracks, where <WAVE> is the brainwave, <FREQUENCY> is the track's frequency, and <SOLFEGGIO_FREQUENCY> is the solfeggio's frequency.

Type Format Example
Pure <WAVE>_<FREQUENCY>.mp3 Alpha_12_Hz.mp3
Isochronic <WAVE>_<FREQUENCY>_Isochronic_Pulses.mp3 Alpha_10_Hz_Isochronic_Pulses.mp3
Solfeggio <WAVE>_<FREQUENCY>_Solfeggio_<SOLFEGGIO_FREQUENCY>.mp3 Alpha_12_Hz_Solfeggio_396_Hz.mp3

data.json contains metadata on binaural beats (frequencies are measured in Hz). It contains five keys representing the five brainwaves: alpha, beta, delta, gamma, and theta, each having the following structure.

Key Optional Data type Explanation Example
minFrequency No number Starting frequency 0.5
maxFrequency No number Ending frequency 4
pure No array Metadata on pure binaural beats [{"frequency": 0.9, "effects": ["Euphoric feeling"], "name": "Delta_0.9_Hz.mp3"}]
solfeggio Yes array Metadata on the binaural beats mixed with solfeggio {"binauralBeatFrequency": 12, "solfeggioFrequency": 396, "effects": ["Designed to ease you into a state of mental awareness"], "name": "Alpha_12_Hz_Solfeggio_396_Hz.mp3"}
isochronic Yes array Metadata on binaural beats mixed with isochronic pulses {"frequency": 10, "effects": ["More intense meditation"], "name": "Alpha_10_Hz_Isochronic_Pulses.mp3"}
explanation No string What this range of binaural beats do "Delta brainwaves are considered the most relaxing brainwave frequency range."
benefits No array of strings Positive effects of this brainwave ["Having high amounts of self-control"]

The structures of pure, isochronic, and solfeggio are described below.
