Abstract: A sound and light machine (SLM) produces sound and light pulses at brain wave frequencies so as to induce a particular state of consciousness in a user, while simultaneously providing music. The SLM includes light emitting diodes (LEDs) and headphone speakers. A microcontroller runs firmware to control the LEDs and headphone speakers so as to produce a plurality of dominant brainwave frequencies. Binaural voices produce a melody of music without interfering with the brainwave frequencies. Each note of the melody is sounded at a specific pitch based on information in a Tone Object, which includes a state variable index holding the note's current position within a waveform array and a state variable step, which is an amount by which to increment the state variable index at each iteration. The index is set to 0 at startup and the step is calculated from the initial note desired.

Abstract: A sound and light machine (SLM) produces sound and light that pulses at brain wave frequencies. The SLM is programmed to induce a particular state of consciousness in a user. The SLM includes a left and a right light emitting diode (LED) (3). The LEDs (3) are configured to be placed in front of the user's left and right eyes, respectively, and are programmed to pulse light at a frequency that helps induce the particular state of consciousness in the user. The SLM has a left and a right headphone speaker (4). The speakers (4) are configured to play different tones into right and left ears to produce binaural beats that match the LED pulse frequencies. The SLM also has a microcontroller (5) on circuit board that runs firmware to control the LEDs and headphone speakers.
