Three bands cover what most recordings need: bass around 100 Hz for weight, the middle around 1 kHz where voices live, and treble around 8 kHz for air and clarity. Each can be raised or cut by up to 15 dB.
Presets give a starting point, from a clear-voice curve for muddy speech to the "small radio" sound. The overall level is lowered automatically when you boost, so the result does not distort.
How to use the Audio Equalizer tool
- Add the recording.
- Choose a preset or move the three sliders.
- Download and listen; adjust and run again if needed.
Popular uses
- Making a muffled voice recording clearer
- Taming harsh, hissy treble
- Adding weight to thin laptop-microphone audio
Tips for the best result
- Cutting what is too loud usually sounds better than boosting what is too quiet.
- For speech, try bass −3, middle +4, treble +2.
