Audio Tools
"Too quiet" has several different causes, and each one has a different fix. Raw gain solves one of them. These tools cover the rest — evening out inconsistent levels, lifting a specific frequency range, or making speech cut through. Each page runs a genuinely different processing chain, all locally in your browser.
Which tool do you need?
Match the symptom to the chain.
- The whole file is just quiet
- Use the audio amplifier — clean gain with limiting.
- Some parts are loud, some are inaudible
- Use the audio normalizer. Gain will not fix inconsistency, only compression will.
- Speech is buried under music or noise
- Use the voice booster to lift the intelligibility range.
- It sounds thin on small speakers
- Use the bass booster — though small drivers have hard physical limits.
- It sounds muffled or dull
- Use the treble booster to lift the high end.
- You want control over specific frequencies
- Use the equalizer for five-band adjustment.
- It needs to be competitively loud
- Use the loudness enhancer, which trades dynamics for level.
- Music specifically needs more punch
- Use the music booster preset chain.
- You want a general lift
- Use the audio enhancer, which combines a gentle shelf pair with light compression.
One engine, different chains
All of these tools share the same underlying audio engine — a Web Audio graph built from a source node, a set of filters, a compressor, a soft-clipper and an analyser. What changes between pages is which nodes are inserted and how they are configured.
That matters for a practical reason: the tools behave consistently. The fader means the same thing everywhere, the headroom meter reads the same way, and the keyboard shortcuts do not change as you move between pages.

- Audio AmplifierStraight gain with a limiter — the tool for files that are uniformly too quiet.
- Audio NormalizerAnalyses peak level and evens out recordings where some parts are loud and others inaudible.
- EqualizerFive-band parametric EQ for shaping specific frequency ranges rather than the whole signal.
- Bass BoosterA low-shelf filter that lifts everything below the cutoff — weight without muddiness.
- Treble BoosterA high-shelf filter for muffled recordings — clarity rather than volume.
- Voice BoosterLifts the 2–4 kHz intelligibility range and compresses, so dialogue cuts through.
- Audio EnhancerA gentle shelf pair plus light compression — the general-purpose improvement chain.
- Loudness EnhancerHeavy compression plus makeup gain — raises average level, not just peaks.
- Music BoosterA shelf pair and limiter tuned for songs — weight and sparkle, not just level.
