Description
Technical field
The present invention relates to acousto-optic control correlative technology field, particularly a kind of full-color acousto-optic conversion control method and system.
Background technology
Existing market LED music lamp mainly is to utilize range value to control the variation of LED lamp, and the LED lamp is mainly the control that white lamp or red/green/Lan Sanse separates.And some LED music lamp is that the control of music and LED light is controlled respectively by two files.
Because not contact between the color, it is narrow that the LED lamp changes colour gamut, and the LED variation is only relevant with rhythm, and the frequency-independent with music makes that the variation of music is more stiff.Separately the LED lamp of control need/colourity bright according to the LED of music making response change file, very dumb, if real-time sound (singing as speech, applause, acute cappela), this mode just has no idea to finish the LED variation effect synchronous with sound.
Sound has height, power, length, four kinds of character of tone color.The height of sound is to be determined by object vibration number (frequency) within a certain period of time.The vibration number multitone is just high, and the few sound of vibration number is just low.The audiorange that common people's ear can be heard is about the 30-17000 hertz.The length of sound is because determine the perdurabgility of vibration, and vibration long perdurabgility is just long, and vibration minor perdurabgility is just short.The power of sound is because amplitude (amplitude) is big or small decision of amplitude of object vibration scope.The big sound of amplitude is just strong, the little sound of amplitude just a little less than.Tone color (timbre or tone color) is to be determined by the pronunciation harmonic wave (harmonic wave) that object produced, character, the shape difference of pronunciation object, and the harmonic wave that is produced is also different, thereby tone color is also different.
The problem that prior art exists is that the variation of LED lamp is only relevant with rhythm, has only reflected the power and the length of sound by light, and change in color is irrelevant with the height and the tone color of sound.The different pitches and the single-tone of different durations just constitute melody continuously, that is to say that the melody of it and music is irrelevant, and melody is the soul of music, is the basis of music, its embodies the whole thoughts or the main thought of music.The LED music lamp of prior art can't offer the sensory experience of people's vision and sound sensation harmony, let alone can allow the deafness can experience magic of music.
