Generating tonally compatible, synchronized neural beats for digital audio files

A system comprising:

• a processor;
• and
• a memory storing instructions which, when executed by the processor, cause the processor to:
• receive a digital audio file and a beat frequency for a neural beat to be added to the digital audio file;
• extract a plurality of chromagram features of the digital audio file according to a plurality of parameters;
• combine the plurality of chromagram features to form primary chromagram features of the digital audio file;
• extract, from the primary chromagram features, dominant pitch classes at a plurality of timestamps within the digital audio file;
• select, based on the dominant pitch classes at the plurality of timestamps, a plurality of carrier frequencies for the neural beat;
• synthesize, based on the beat frequency and the plurality of carrier frequencies, a synchronized neural beat for the digital audio file;
• store in the memory at least one of (i) the synchronized neural beat and (ii) a combined audio track combining the synchronized neural beat and the digital audio file;
• and
• cause an audio output device to (i) play the combined audio track or (ii) play the synchronized neural beat in parallel with digital audio file.

A method, comprising:

• receiving at a server a digital audio file and a beat frequency for a neural beat to be added to the digital audio file;
• extracting a plurality of chromagram features of the digital audio file according to a plurality of parameters;
• combining the plurality of chromagram features to form primary chromagram features of the digital audio file;
• extracting, from the primary chromagram features, dominant pitch classes at a plurality of timestamps within the digital audio file;
• selecting, based on the dominant pitch classes at the plurality of timestamps, a plurality of carrier frequencies for the neural beat;
• synthesizing, based on the beat frequency and the plurality of carrier frequencies, a synchronized neural beat for the digital audio file;
• creating a combined audio track combining the synchronized neural beat and the digital audio file;
• and
• sending the combined audio track combining the synchronized neural beat and the digital audio file to a user device.
