Simply put, Viper Sound 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 kind of audio processing software or hardware is sometimes called "convolver" or "reverberator". With it, you can almost do whatever you want-you can even let your favorite singer sing for you in your bathroom.
