Bass booster onlinewith controlled headroom

Open the file, let the browser decode it, and the low shelf starts at +6 dB with a −6 dB preamp already applied. Move the bass control until it sits where you want, compare against the original, and export. Nothing is uploaded and no account is needed.

Listen at the loudest part rather than the chorus you like. If the low end starts to sound loose instead of fuller, or the rest of the track seems to duck behind it, you have gone past what the material carries. Most recordings take 3 to 6 dB comfortably; 12 is a deliberate effect.

No. Equalization can emphasise low-frequency content that is already there, but it cannot recreate fundamentals removed by the microphone, by filtering, or by heavy compression. Boosting silence gives louder silence.

Boosting a frequency range raises peaks. The negative preamp creates headroom before the boost arrives, so the file does not clip the moment you start.

Small drivers cannot move enough air to reproduce the lowest frequencies, so the boost is there in the file and inaudible on that speaker. Judge it on headphones, and remember that a boost you cannot hear on a phone can still distort it.

It is a conservative guide based on the settings, not a measurement of the rendered file. Source spectrum, phase and overlapping filters all affect the real peak, so listening and a final peak check still matter.

Almost always the peak went past full scale. Lower the boost, or keep it and reduce the overall level with the volume tool, then export again. Distortion that was already in the recording will only become more obvious with more bass.

A low shelf cornered at 320 Hz, which lifts everything below it rather than one narrow band. For a specific region instead — a room resonance, say — use the equalizer, which offers 3, 10 or 20 fixed bands.

This page is the equalizer with one job set up for you: a low shelf, a preamp for headroom and a clipping estimate. Go to the equalizer when you want to shape more than the bottom end, or when you want to cut something while you lift.

Yes, and the export formats are the ones those platforms accept. Keep in mind that heavy boosting plus platform loudness normalisation often ends up quieter overall, not louder.

Common audio and video containers are accepted; the editor tries native decoding first and falls back to a local FFmpeg build. Exports are MP3 from 64 to 320 kbps, 16-bit PCM WAV, M4A/AAC at 192 kbps, and FLAC.

No. The audio is decoded and boosted in this browser tab and is not sent to the application server. The page itself still loads site resources and consented analytics.
