Description

How to change the action as the music transitions

The present invention relates to a method for changing the action with the transition of music, in particular, an electronic device first performs Fourier series transformation on the sound signal emitted by at least one musical instrument to obtain a rhythm diagram of the sound signal, and the intensity of the rhythm diagram is equal to that of the sound signal. When the intensity of the waveform graph of the sound signal and the size of the spectrogram drop to a preset percentage at the same time, the action device will execute the action, so that the music can change the action at the time of transition.

Press, with the rapid development of science and technology, pure listening enjoyment has been difficult to meet people's sensory needs, so more and more music equipment will visually entrust the audience with more experience to provide the audience in the process of listening to music. However, most of the music and lighting interactive devices are controlled by lighting manufacturers through system presets, for example: in the program in advance with the music playing, or It is to adjust the color and brightness of the light through the style and rhythm of the music, and it can be broadcast at the same time when the performance is on.

However, this pre-set method cannot make the combination of music and lighting achieve the optimal effect, and may also make the sensory experience unsatisfactory, so as to reduce the live music atmosphere, and if the number of music is too large At this time, lighting manufacturers will spend a lot of time and effort, so most of them will not provide a lighting interaction for each piece of music. Moreover, at present, lighting manufacturers are based on the size of the sound and the conversion position of the frequency. brightness However, through the above two methods, the interaction of the lights will be too disordered, which will cause discomfort. However, people feel that the combination of music changes because of the rhythm in the music, and the rhythm is the time, sequence, and strength of the music. The rhythm will make the music progress in an orderly manner.

However, at present, when music is played or broadcast, the background sound and light effects remain unchanged. When the music (such as a symphony) transitions, the tracks will be replaced. If the background sound and light effects do not change, the audience will feel the visual effect. If it is not good, the sensory experience of the live music is not good and boring, which in turn affects the audience's willingness to watch it again.

Therefore, how to automatically extract the rhythm from the music and produce the action effect in accordance with the rhythm is the direction that the relevant industry in this industry is eager to study and improve.

Therefore, in view of the above deficiencies, the inventor collects relevant information, evaluates and considers from various parties, and uses years of experience in this industry, through continuous trial production and modification, to design such a movement that changes with the transition of music. The invention patentee of the method.

The main purpose of the present invention is that the electronic device can first perform Fourier series transformation on the sound signal emitted by at least one musical instrument to obtain a rhythm diagram of the sound signal, and use the electronic device to analyze the rhythm diagram and intensity waveform in the sound signal. If the intensity of the rhythm graph, the intensity of the waveform graph, and the size of the spectrogram decrease to a preset percentage at the same time and maintain the preset time, the time point will be regarded as the rhythm paragraph point, at this time, the sound signal of the music will disappear, and the electronic device will transmit an action signal to the action device at the rhythm paragraph point, and after the action device receives the action signal, it will execute the phase according to the action signal. The corresponding action can enable the action device to perform the action according to the rhythm played by at least one musical instrument, so that the music can change the action at the transition time, thereby improving the music The overall purpose of performance viewing.

[Fig. 1] is a rhythm diagram of the present invention.

[Fig. 2] is a flow chart of the present invention.

In order to achieve the above objects and effects, the technical means and structures adopted by the present invention are described in detail with reference to the preferred embodiments of the present invention, and the features and functions are as follows, so as to be fully understood.

Please refer to Figures 1 and 2, which are rhythm diagrams and flow charts of the present invention. It can be clearly seen from the figures that the following steps are included:

(A) The electronic device can first perform Fourier series transformation on the sound signal emitted by at least one musical instrument (such as guitar, drum, bass, piano, cymbal or other musical instruments) in music to obtain a rhythm diagram of the sound signal, which is The rhythm diagram represents the intensity change of at least one frequency in the sound signal over time.

(B) The electronic device then performs the rhythm segment point 1 capture action on the rhythm graph, the intensity waveform graph and the spectrogram in the sound signal. When the percentage is set and the preset time is maintained, this time point will be regarded as the rhythm segment point 1. At this time, the sound signal of the music will disappear, and the electronic device will transmit the action signal to the action segment at the rhythm segment point 1. device.

(C) After the action device receives the action signal, it will execute the corresponding action according to the action signal, so as to complete the use of the present invention.
