What is the loudness setting on some speakers doing?
In: Technology
It usually boosts bass a lot and treble a bit too.
Our ears are less sensitive to bass and treble when listening to quiet sounds, so the boosts can help to compensate for this.
Usually it’s turning on some type of audio compression (not to be confused with data compression like mp3). Audio compression is another tool like eq that is used both on the creation and playback side.
Compression squeezes the waveform peaks, so that the loud parts are less loud and the quiet parts are less quiet. This allows you to then boost the whole signal up to a point that it’ll sound louder to the human ear.
