Upload an audio file, adjust ten frequency bands from 31 Hz to 16 kHz, compare the change with Bypass, then export a WAV or MP3 file.
Adjust Frequencies in an Audio File
An audio equalizer changes the level of selected frequency ranges in a recording. Use it when bass is too prominent, a voice needs a different balance, or the treble needs adjustment.
This online audio equalizer gives you ten sliders from 31 Hz to 16 kHz. Upload a track, choose Flat, Bass, Vocal, or Bright, and adjust the curve before you download it.

Reduce bass under dialogue
Lower low-frequency bands in a music bed when the bass competes with spoken audio in a finished video.
Improve speech clarity
Use the Vocal preset or adjust middle-frequency bands for narration, an interview, or a voice-led track.
Reduce sharp high frequencies
Lower upper bands when cymbals, vocals, or other details make the track sound sharp.
Prepare Audio for Its Next Use
This audio equalizer works with the recording you already have. Adjust the EQ for a music demo, a video soundtrack, or a spoken clip, then export the version you want people to hear.
The tool keeps the choice simple: choose a preset or move the bands yourself, use Bypass to compare, then download WAV or MP3.

Use Bypass to Check Each Change
Bypass temporarily turns off the EQ while the loaded audio keeps playing. Use it at the same point in a song, video soundtrack, or voice clip to hear what the adjustment does before you export.
Choose the Frequency Range to Adjust
Name what you hear first, then work on the part of the EQ that affects it. The ten bands make it possible to change low, middle, and high frequencies separately.
When bass feels too heavy
Lower low-frequency bands when bass leaves too little room for a melody, vocal, or spoken words.
When a voice needs adjustment
Adjust middle-frequency bands when a vocal, narration, or lead part needs a different balance.
When treble sounds dull or sharp
Raise or lower high-frequency bands to change the amount of detail and sharpness in the track.
Pick a Starting EQ Curve
Each preset changes the same ten frequency bands in a different way. Choose the curve closest to your goal, listen to it on your track, and edit any slider that needs work.
Start with a bass EQ curve
Use Bass when a music track needs a low-frequency starting curve. Preview the result, then change any of the ten bands to match the recording.
