A personalized music binaural difference frequency sleep aid method
By using a method based on Hilbert transform and complex exponential frequency shift, the user-selected music is processed by binaural difference frequency to generate binaural difference frequency auditory stimulation with a frequency difference of 0.5-2 Hz. This solves the problems of shallow music fusion and inaccurate difference frequency control in existing technologies, and achieves personalized sleep aid and synchronization effects.

AI Technical Summary
Existing binaural frequency difference sleep aid technology lacks deep integration with music, has imprecise frequency difference control, and is difficult to synchronize with slow-wave sleep waves, which may produce a mechanical or unnatural listening experience. In addition, users need to switch to pure tone or separate sleep-inducing sound sources.
Using a method based on Hilbert transform and complex exponential frequency shifting, the music signal is processed by binaural difference frequency to generate a binaural difference frequency auditory stimulation signal with a frequency difference of 0.5-2 Hz. Combined with the user's favorite music, personalized sleep aid is achieved by using frequency shifting technology while maintaining the original duration and rhythm of the audio.
It achieves deep integration with the user's favorite music, personalized sleep aid effect, improved ease of use and compliance, and can maintain synchronization with slow wave sleep waves throughout the process, providing stable binaural differential frequency stimulation.
