Music equipment appears one after another in our lives, such as MP3s, Walkmans, stereos, amplifiers, etc., which makes us somewhat dizzying. It is their existence that makes Our spiritual world and entertainment life have become more colorful. Friends who like music probably know what a mixer is. A mixer is another advanced musical equipment after the power amplifier, but its function is not fully understood by everyone. This article will give you a comprehensive analysis and introduction.
1. The basic functions of the reverberator:
1. It can change the reverberation time of the hall and reprocess the "dry" signal to increase the sense of space and improve the sound. The fullness of the system.
2. You can artificially create some special effects, such as the echo effects of valleys and caves, etc.
3. By adjusting the ratio of reverberation sound and direct sound, the distance and depth of the sound can be reflected.
2. The sound effects of the three basic sound effects of the mixer
1.? Sound field effect
The sound field effect is to imitate different sounds under on-site conditions. Sound field effect under conditions. Such as Room (room) reverb, Hall (hall) reverb, Church (teaching) reverb, Studio (studio) reverb, KaraOK (karaoke OK) reverb and other sound field effects. Mainly used in live sound reinforcement systems. The main adjustment parameters are reverberation time, attenuation of the reverberation spectrum, delay, and the mixing ratio of "dry" and "wet" sounds. Digital signal processors mainly use DSP processing chips.
2.? Special effects? Special effects sound is mainly used for background effects in theater sound reinforcement, sound processing during live band performances, special sound effects processing for movie recordings and studio recordings, etc. There are many types of special effect sounds, such as Chorus (chorus) effect, Echo (echo) effect, Pitch (pitch) effect, Gate (gate) effect, and the illusive sound effects formed by the superposition and combination of the above effects. The following introduces the principles of several typical special effects sound production.
(1) The Pitch pitch change (pitch transposition) effect uses 440Hz as the benchmark and moves the spectrum of the music signal up or down one octave, which will move the pitch of the music one degree.
(2)Echo echo effect? ??Echo adjusts the delay of the reverberation spectrum to more than 100ms. The longer the delay time, the longer the echo interval.
(3) Chorus chorus effect? ??If the music spectrum is modulated with an ultra-low frequency of 0.1Hz~10Hz, so that the original music spectrum moves repeatedly with the modulation frequency, the periodicity of the tone can be produced change.
3. Sound source processing effects
Perform effect processing on various sound source signals to create specific sound source effects. The effect device is specially equipped with MIDI interface for electronic musical instruments, drum machines (electronic beat machines) and percussion instruments.
The above content is a carefully prepared introduction to the function of the mixer. In fact, there are many types of mixers, and their functions and applicable occasions are also different, but their most critical function is Covering up the shortcomings and shortcomings of people's singing skills when singing and making up for it, just like "cheating", so that even if a group of people are singing karaoke, they don't have to worry about being laughed at if they sing poorly. This is also There is an important reason why the mixer is favored by everyone. Friends who are interested in it can buy one and give it a try. You will definitely make unexpected discoveries.
