A-law algorithm

A-law algorithm is a type of computer program that helps make sound louder or softer. It works by reducing or increasing loud parts of the sound, and making quiet parts of the sound louder or softer. This means that the louder parts of the sound become less loud, and the quiet parts of the sound become louder or softer. This makes the sound easier to hear.
