Audio equaliser. Bass, mid, treble.
Add weight, lift a voice out of a muddy recording, or take the hiss off an old tape. Three bands in decibels — and unlike a volume control, moving one leaves the others where they were.

Common questions
How is this different from turning the volume up?+
A volume control moves everything together. An equaliser moves one part of the sound and leaves the rest where it was — turning the bass up should not make a cymbal louder. Each band here is two octaves wide around its centre frequency, which is what keeps them independent enough to be useful and wide enough to sound natural.
What do the three bands actually cover?+
Bass is centred on 100 Hz — weight, warmth and rumble. Mid is centred on 1 kHz, where most of a speaking or singing voice lives. Treble is centred on 6 kHz: air and detail, and also tape hiss and sibilance, which is why pulling it down is the usual fix for a harsh recording.
How much is too much?+
The range is ±15 dB, which is far more than most material needs. Cutting generally sounds better than boosting: if a recording is muddy, taking a few dB out of the bass usually beats adding treble, because boosting raises the noise along with the signal.
Will it clip or distort?+
Boosting adds energy, so a track already mastered close to full scale can be pushed into clipping by a large boost. If the result sounds crunchy, use a cut on the bands you don't want instead of a boost on the one you do — the balance is the same and the level stays under control.
