DSP is a shorthand for English (digital signal processing). Its working principle: the microphone collects external environmental noise, and then through the noise reduction system function inside the headset, it copies and generates a reverse sound wave equal to the external environmental noise to cancel the noise, so as to achieve Better noise reduction effect.
 
CVC is the abbreviation of English (Clear Voice Capture). It is a software noise reduction technology. Its principle is to suppress various types of reverberation noise through the noise cancellation software and microphone built in the earphone.
The difference between the two:
 
1, for the object is not the same, CVC technology is mainly for the echo generated during the call, DSP is mainly for the external environment of high and low frequency noise.
