What is impulse response in convolution?

The impulse response function is a useful transfer characteristic of a signal processing unit, since it allows us to estimate the expected distortion of a signal passing through it. Convolution.

Why impulse response is used in convolution?

Convolution allows you to determine the response to more complex inputs like the one shown below. In fact, you can use convolution to find the output for any input, if you know the impulse response. This gives incredible power. There are several ways to understand how convolution works.

What is impulse response in audio?

An impulse response is created by playing a sound, or an impulse, in a space. This impulse can either be a short, percussive sound (a starter pistol, a clapboard / slate, a balloon popping, etc.) or a more sustained sound like a sine sweep (a sine tone that pitches up through the audible frequency spectrum).
