Bass boosting raises the lower part of the frequency spectrum to give drums, bass lines, sound effects, and thin recordings more weight. This tool opens with a balanced bass preset while keeping all ten equalizer bands available for fine adjustment.
The preset emphasizes 31, 62, and 125 Hz, then tapers through the low mids so the result is fuller without simply making the whole file louder. Reduce 250 or 500 Hz if extra bass makes the mix sound muddy.
Use the live Original and Equalized controls to judge the change at the same playback position. Moderate boosts usually translate better across headphones, phones, car speakers, and small Bluetooth speakers than pushing every low band to its maximum.
Clipping protection is enabled by default because bass-heavy peaks can exceed the available headroom. You can also choose Voice, Podcast, Treble Boost, or Flat and use this page as a complete 10-band audio equalizer.
