vanishing point

This video illustrates the distance effect caused by reverb.

The filter as a “band pass” setting: the high and low frequencies were filtered out. The sound is thinned, which accentuates the effect of distance.

The sound [music box] has been installed in two tabs. In the first, it is untreated and at a higher volume.

They are both started at the same time and then gradually the volume of sound 1 is decreased, which gradually reveals the sound 2 (the treated version).
