Using reverb
Natural reverb occurs when sound waves bounce off a surface and reflect back at a listener. The timing and amplitude of the reflected audio exhibit some variation compared to the original. Over time, the amplitudes and frequencies in the sound wave decrease and the sound dissipates.
You can think of reverb as making your sound feel further away. The more reverb you add, the further away your sound will feel and the larger the space the sound will appear to exist in. Reverb is actually a separate sound that is played (you can play just the reverb of a sound without hearing the original source), but our ears get tricked and interpret the original and the reverb as if they are connected as a single sound.
In general, reverb is the last effect you want to apply in the signal chain to your sound.
There are two kinds of reverb: algorithmic digital reverb and convolution reverb. Let’s take a look at each of these.
