About
Use this free online audio equalizer to boost bass, lift voices or soften a harsh treble. Load an MP3, WAV, M4A, OGG, AAC or MP4 file and move five sliders, each from -12 dB to +12 dB. Five presets give you a starting point: Flat, Bass Boost, Vocal, Treble and Podcast.
The five bands are 60 Hz (Sub Bass), 250 Hz (Bass), 1 kHz (Mid), 4 kHz (Presence) and 12 kHz (Treble). Lower the 60 Hz band to cut rumble, raise the 4 kHz band to bring speech forward, or lower the 12 kHz band to take the edge off a bright recording.
Export applies the settings to the whole file and saves a new copy with -eq added to its name, so the original stays as it was. You can export MP3 or WAV.
