If the low end feels too heavy or the high end too sharp, start with one EQ band. Make a small adjustment so you can hear what it changes.

How It Works

Step 1Choose the part of the sound to change
Step 2Use the EQ knobs for one consistent adjustment

Choose the part of the sound to change

Choose one MP3, WAV, OGG, FLAC, M4A, AAC, or WMA file, up to 100 MB.

ControlWhere to start
BassAdjusts a band around 80 Hz. Try a small reduction if the low end feels too heavy.
MidAdjusts a band around 1 kHz. Use a small change when the middle of the sound needs more or less emphasis.
TrebleAdjusts a band around 8 kHz. Try a reduction if the high end feels too sharp.

Use the EQ knobs for one consistent adjustment

Under EQ, adjust Bass, Mid, or Treble. Each starts at 0 dB and ranges from −12 to +12 dB. If the bass feels too heavy, for example, try −2 dB before making a larger cut.

Use the EQ knobs throughout this pass and leave the separate Options sliders unchanged. The two sets of controls do not share the same settings.

Keep Format at MP3 and click Process Audio Equalizer. Compare the result with your original at a similar listening level: extra volume can make a change sound better even when the balance is wrong for your recording.

Choose Download to save the processed copy. The tool may also start the download automatically after processing.

Questions about audio equalizer

An equalizer changes selected frequency ranges across the recording. It can reduce an unwanted tonal emphasis, but it also changes useful sound in the same range. Use Audio Denoise when the main task is reducing background noise.

Try reducing low-frequency emphasis before boosting everything else. Make small adjustments and compare with the original at a similar volume. Equalization changes tonal balance; it does not separate a voice from overlapping speakers or background music.

Boosting several bands increases the overall level as well as changing tone, which can cause distortion. Use smaller boosts or cut frequencies that are too prominent. Check the output level after changing EQ.
