Abstract

A method for incorporating brain wave entrainment into an audio composition by selectively modulating musical elements within the composition. The invention provides a way to specify and modulate individual frequency components in an audio composition, according to the desired brain wave state, allowing brain wave entrainment to be easily and subtly incorporated into an audio composition by disguising the modulations as natural instrumental qualities such as vibrato or reverberation.

Claims

1. ) A method for altering an audio composition for use in achieving brainwave states and stimulating the brain, comprising the acts of:

a) selecting an audio composition, the audio composition comprising a plurality of frequency components;

b) selecting a brainwave protocol, the brainwave protocol comprising the desired brain wave frequencies across a timeline of the audio composition;

c) separating the audio composition into a plurality of signals;

d) modulating at least one of the plurality of signals according to the selected brainwave protocol; and

e) remixing the signals to produce a final output.

2. ) The method according to claim 1, wherein the audio composition is in digital format.

3. ) The method according to claim 1, wherein the act of separating further comprises a band pass filter.

4. ) The method according to claim 1, wherein the act of separating further comprises a band stop filter.

5. ) The method according to claim 1, wherein the plurality of frequency components are categorized by musical instrument.

6. ) The method according to claim 1, wherein the act of modulating further comprises amplitude modulation.

7. ) The method according to claim 1, wherein the act of modulating further comprises the act of stereo panning.

8. ) The method according to claim 1, wherein the act of modulating further comprises frequency modulation.

9. ) The method according to claim 1, wherein the final output is in a digital audio format.

10. ) The method according to claim 1, wherein the brain wave protocol comprises a chart representing time horizontally and desired brain wave frequency vertically.

11. ) A method for altering an audio composition for use in achieving brainwave states and stimulating the brain, comprising the acts of:

a) selecting an audio composition having a plurality of frequency components;

b) selecting a brainwave protocol, the brainwave protocol comprising the desired brain wave frequencies across a timeline of the audio composition;

c) filtering at least one of the frequency components independently from the other frequency components;

d) modulating the filtered frequency component according to the brainwave protocol; and

e) remixing the signals to produce a final output

12. ) The method according to claim 11, wherein the act of modulating comprises a band pass filter.

13. ) The method according to claim 11, wherein the brain wave protocol comprises a chart representing time horizontally and brain wave frequency vertically

14. ) A method for producing an audio composition for use in achieving brainwave states and stimulating the brain, comprising the acts of:

a) generating a plurality of frequency components;

b) selecting a brainwave protocol comprising brain wave frequencies across a timeline of the audio composition;

c) modulating at least one of the plurality of frequency components according to the brain wave protocol wherein at least one of the plurality of frequency components is modulated independently of the others; and

d) mixing the modulated frequency components with the non-modulated frequency components into a final sound output.

15. ) The method according to claim 14, wherein the plurality of frequency components are categorized by musical instrument.

16. ) The method according to claim 14, wherein the act of modulating further comprises amplitude modulation.

17. ) The method according to claim 14, wherein the act of modulating further comprises the act of stereo panning.

18. ) The method according to claim 14, wherein the act of modulating further comprises frequency modulation.

19. ) The method according to claim 14, wherein the final output is in a digital audio format.

20. ) The method according to claim 14, wherein the brain wave protocol comprises a chart representing time horizontally and desired brain wave frequency vertically.
