The reverberator synchronously transmits the tonic of the microphone. After attenuation, it takes a part of the amplitude of the tonic, A/D converts it into digital quantity, and delays it (the time length can be adjusted), then takes a short segment, and then D/A converts it into analog sound, and then sends it back to be superimposed on the tonic, and the tonic will continue to be superimposed in a cyclic delay way. This creates an effect similar to the echo in the lobby in reality.

There are two adjustable parameters, one is the amplitude returned by superposition. One is the length of delayed return. Reverberation in nature is a phenomenon that sound waves are repeatedly reflected or scattered by indoor interfaces or obstacles after indoor sound sources stop sounding.

Extended data:

A sound system usually includes:

1, audio equipment: (listed as: DVD, CD, MP3, MP4, computer, mobile phone, microphone and other audio output equipment)

2. Audio signal dynamic processing equipment (voltage limiter, effector, mixer, audio processor, equalizer and other audio signal processing equipment).

3. Audio signal amplification equipment (analog power amplifier and pre-stage power amplifier, post-stage power amplifier, digital power amplifier and other equipment).

4. Sound reproduction equipment (full range speakers, ceiling speakers, pillars, linear array speakers, array speakers, tweeters, subwoofers, etc.). The development history of technology can be divided into four stages: electron tube, transistor, integrated circuit and field effect tube.
