Frequently Asked Questions
How do I add more bass to a song?
Upload your WAV file and raise the low-frequency bands (31 Hz, 62 Hz, 125 Hz) on the 10-band equalizer. Preview the result live and download once it sounds right — free, no software needed.
How do I boost the treble or vocals?
Lift the higher bands (2 kHz–8 kHz) to brighten a track and make vocals cut through. Cut the 200–500 Hz range slightly if the mix sounds muddy.
What is a 10-band equalizer?
A 10-band EQ lets you cut or boost sound at ten fixed frequencies (31 Hz to 16 kHz), so you can shape bass, mids, and treble independently.
What audio formats does the equalizer support?
This tool works on WAV files. Convert your MP3 or other files to WAV first using our free MP3 to WAV converter.
How much can I boost or cut each band?
Each band can be adjusted from -24 dB to +24 dB.
What does the Q value do?
Q controls how wide each band affects the frequency spectrum. Lower Q = wider, more musical adjustments; higher Q = tighter, surgical cuts.
