Jiangsu Shenguang Electronic Technology Co., LTD. 's "drive sound head" concept may have different meanings in different fields.

First, in the field of music

Definition and interpretation

In percussion, the head is the instant state at which a sound begins. Driving the sound head is to emphasize the sense of power and push of this initial moment, so that the sound can be very impact at the initial stage, in order to drive the rhythm and atmosphere of the entire music. For example, in drum performance, when the drummer beats the drum or the floor drum to open a rhythm pattern, through the explosive force of the wrist and arm, the moment the drumstick hits the drum face produces a clear and powerful sound, which is like adding a strong starting engine to the rhythm train of music.

For some wind or string instruments, the driving head is also important. In the case of the trumpet, the player uses the tension of the lips and the instant burst of breath to make the first note of the trumpet have enough energy, and the intensity and texture of this initial note can guide the whole passage. In string playing or pizzicato, as at the beginning of a forte, the initial movement of the fingers or bow is fast and strong, producing a driving head.

Application scenarios and effects

In rock music, a strong driving head is an important part of its rhythm. For example, in the strong force and string playing of the electric guitar, the guitarist plucks the strings hard to make the starting note of each string very prominent. This driving sound head combined with the strong drum rhythm can create an exciting and powerful musical atmosphere, so that the audience is easily driven by the energy of the music.

In some grand movements of classical music, such as the beginning of the timpani rolling in a symphony, or the beginning of the chorus of brass instruments, the driving head can show the majesty and magnificence of the music, laying a solid foundation for the development of the entire musical work.

Second, in the field of audio technology

Definition and interpretation

From the signal processing point of view, the driving sound head may involve the processing of the initial stage of the audio signal. When recording or synthesizing sound, the head is enhanced or modified in order to make the sound more attractive at the beginning of playback or more suitable for a particular auditory effect. For example, through devices such as compressors and limiters, the dynamic range of the initial stage of the audio signal can be adjusted so that the sound head can be more prominent. The compressor can compress the signal in accordance with the set proportion when the signal exceeds a certain threshold, so that in the sound head part, if there is a momentary high level signal, it can be properly compressed to make the sound head tighter, while increasing the overall volume without overloading distortion.

Application scenarios and effects

In electronic music production, many electronic drum timbre or synthesizer timbre designs focus on driving heads. The producer controls the driving characteristics of the soundhead by adjusting the synthesizer's envelope parameters, such as the Attack parameter. If the Attack parameter is set to a short value, the sound will quickly rise to a peak, producing a sharp, powerful soundhead suitable for the production of strong rhythmic electronic dance music. This processed driving head can penetrate through complex electronic music mixes, making rhythms and melodies more audible.
