Flatten directory structure

v6.0.2

Release v6.0.2

Synchronize data.json with tracks/

The track Beta_14_Hz.mp3 was removed from data.json because it did not exist in the tracks/ directory.

Legalize

Previously, two of the tracks (Alpha_8_Hz.mp3 and Delta_4_Hz.mp3) were only allowed for redistribution for personal uses. This release has deleted those two tracks so that the dataset may be used even commercially.

Smaller file sizes and better metadata

• Improved documentation
• The keys pureRanges, solfeggioRanges, and isochronicRanges have been renamed to pure, solfeggio, and isochronic respectively.
• Tracks are guaranteed to be valid HTML ids. 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.
  • Pure: <WAVE>_<FREQUENCY>.mp3 (e.g., Alpha_8_Hz.mp3)
  • Isochronic: <WAVE>_<FREQUENCY>_Isochronic_Pulses.mp3 (e.g., Alpha_10_Hz_Isochronic_Pulses.mp3)
  • Solfeggio: <WAVE>_<FREQUENCY>_Solfeggio_<SOLFEGGIO_FREQUENCY>.mp3 (e.g., Alpha_12_Hz_Solfeggio_396_Hz.mp3)
• Pure and isochronic tracks have been shortened to one second each.
