The brand fountain design company has designed a movable music fountain for entertainment. The music fountain changes with the music, adding a beautiful visual and auditory feast to the people of the city at night. It is a fast-paced urban life. A rather romantic and leisurely entertainment project at night. So, how much do you know about music fountain design music playback?

Music fountain design tone and its extraction method:

Volume, pitch and timbre are three subjective quantities that reflect the characteristics of sound. They collectively reflect the human ear’s perception of the sound. The pitch reflects the human ear’s subjective perception of the pitch of the sound. Although the musical fountain design pitch is also related to other factors such as sound pressure, it mainly depends on the frequency. Therefore, the higher the frequency, the higher the pitch, and the lower the frequency, the lower the pitch.

The frequency determines the pitch, so the detection of the pitch is mainly the detection of the fundamental frequency, that is, the study of the pitch period. The design system of the brand fountain design company adopts the traditional autocorrelation fundamental frequency detection algorithm, which is an algorithm based on the time domain analysis theory, which has the advantages of simplicity and small amount of calculation, and can directly obtain the sampling value of the time domain signal from related functions. Users can write their favorite music programs in the editing interface. The playback system can realize the unified atmosphere of music, water and lighting in the design of the musical fountain, and the playback is synchronized.
