What is the principle of viper sound effect?

Simply put, Viper is an audio processing software based on the so-called "convolution". It is based on the principle that the output of a linear system can be obtained by convolving its input signal with the impulse response of the system. Many things can be regarded as a linear system-from Beats headphones to China Grand Theatre Concert Hall; -) Obviously, it can also be a completely artificial listening environment (such as an oversized subwoofer). This audio processing software or hardware is sometimes called "convolver" or "reverberator". With it, you can do almost anything you want-you can even let your favorite singer sing for you in your bathroom.
