Abstract
A device, method, and medium for integrating monaural and binaural beats into music are provided. The music is analyzed to determine key, root tone, and spectral range. It is then remixed with monaural beats and/or binaural beats at frequencies based on a desired entrainment frequency and the root tone and lowest dominant frequency range of the music. Additional harmonics of the beats in higher octaves may be integrated into the music as well using mixing and/or equalization.
Claims20
A processor-implemented method for integrating auditory beat stimuli into music, comprising:
- identifying a root tone frequency of an unmodified music signal;
- selecting a first beat frequency based on a desired brainwave entrainment frequency;
- generating a first beat component having a frequency equal to the root tone frequency;
- generating a second beat component having a frequency equal to the root tone frequency shifted by the first beat frequency;
- generating a first audio signal comprising a first portion of the unmodified music signal lying within a first frequency range, the first frequency range comprising a low-pass frequency range with a high-end cut-off frequency equal to a first filter frequency, the first filter frequency being equal to the root tone frequency shifted by the first beat frequency;
- mixing the unmodified music signal with the first audio signal, the first beat component, and the second beat component to produce a modified music signal;
- and
- presenting music via an audio output device driven by the modified music signal.

A device for integrating auditory beat stimuli into music, comprising:
- a root tone detector for identifying a root tone of an unmodified music signal;
- a first oscillator for generating a first beat component having a frequency equal to a root tone frequency, the root tone frequency being based on the root tone;
- a second oscillator for generating a second beat component having a frequency equal to the root tone frequency shifted by a first beat frequency, the first beat frequency being based on a desired brainwave entrainment frequency;
- an equalizer for applying a first filter to the unmodified music signal to generate a first audio signal comprising a first portion of the unmodified music signal lying within a first frequency range, the first frequency range being based on a first filter frequency, the first filter frequency being equal to the root tone frequency shifted by the first beat frequency;
- and
- a mixer for mixing the unmodified music signal with the first audio signal, the first beat component, and the second beat component to produce a modified music signal.
