Embodiment 1

[0023] A kind of double-frequency music production eliminates the method for the influence of background music on the frequency difference, it comprises the following steps:

[0024] S1, first delete background music and the same frequency part as the base frequency for generating dual-frequency music;

[0025] S2, then reduce the volume of the background music that overlaps with the base frequency by more than 15 decibels;

[0026] S3, then the stereo background music processed by S1 and S2 becomes monophonic;

[0027] S4, then the background music processed in the above 3 steps is mixed with the prepared dual-frequency music;

[0028] S5, then output the synthesized dual-frequency music with background music;

[0029] S6. When outputting, select the Wave waveform format to store, and then convert it into MP3 or other formats.

[0030] The part of background music without frequency difference that affects the basic frequency of dual-frequency music is shielded, and after t...

Abstract

The invention discloses a method for eliminating the influence of background music on frequency difference in double-frequency music production, and relates to the technical field of music therapy. The method comprises the following steps of: deleting a frequency part with the same basic frequency as background music and generated double-frequency music; reducing the volume of the background musicafter the background music is deleted to be overlapped with the basic frequency by more than 15 decibels; changing the background music of the stereophonic sound processed in the step S1 and the stepS2 into a single track; mixing the background music processed in the three steps with the prepared double-frequency music; outputting the synthesized double-frequency music with the background music;during output, selecting a Wave waveform format for storage, and then converting the waveform into an MP3 or other formats. By processing the background music, after the background music is added, the frequencies of the left channel and the right channel of the double-frequency music are kept constant, and the frequency difference still exists, so that the uncomfortable feeling of the single double-frequency music in use is eliminated, and the application of the double-frequency music in the health field is quickly popularized.

Description

technical field [0001] The invention relates to the technical field of music therapy, in particular to a method for producing dual-frequency music to eliminate the influence of background music on frequency difference. Background technique [0002] Dual-frequency music means that the frequencies of the left and right channels are inconsistent and constant, so there is a frequency difference (the frequency difference between the left and right channels). Physicist Heinrich Dove discovered that when the frequencies of the left and right sound channels are not equal, the brain will detect the frequency difference, and simultaneously form brain waves equal to the frequency difference in the left and right brains. For example, the base frequency of the left channel is 190 Hz, the base frequency of the right channel is 200 Hz, and the frequency difference is equal to 10 Hz. After 10 minutes, the brain will form a brain wave of 10 Hz (the brain wave is synchronized with the frequen...
