## Variable Documentation

const int MAX_VOLUME = 128 * 128`[static]`

The theoretical maximum volume for a single sound sample.

Multiple sound samples should not exceed this limit as it will sound too loud. It also stops overflowing when too many sounds are played at the same time, which causes an even worse sound quality.
