Audio equalizer
Add background music or recording files and adjust the balance from bass to treble with presets or the frequency and gain for each band. Compare tracks with overly strong bass or material whose treble needs adjustment against the original audio, and save the adjusted audio in your chosen format. If clipping occurs, lower the gain and check again.

Adjust by frequency band11 controls · 0 dB
At 0 dB, this control leaves the volume unchanged. Positive values boost it, and negative values reduce it.
Normally, leave the overall control at 0 Hz. Selecting a preset also resets the frequencies to their standard values.

About frequency and gain
Frequency is the range to adjust
Lower Hz values correspond to lower sounds, and higher Hz values to higher sounds. Adjust band frequencies from a preset if needed.
Gain is the strength of that band
Positive dB increases the level and negative dB decreases it. 0 dB means that item does not change the volume.
How it differs from overall volume adjustment
An equalizer changes the balance of individual bands. To increase or decrease the entire audio uniformly, use the audio volume changer.
Preview if you boost too much
Boosting several bands may cause distortion. Lower the gain while checking the result.
