    Options

    Air-conditioning hiss, electrical hum, café chatter, the reverb of an empty room: this audio noise remover targets the sounds that make a recording tiring to listen to, even when the voice itself is perfectly audible.

    The processing relies on a neural network trained on speech, running on our own server. In our measurements, a recording at a 5-decibel signal-to-noise ratio gains close to 7 decibels — nearly three times what a classic spectral filter achieves.

    The level is then normalized to −16 LUFS, the value podcast platforms expect: your episode will be neither louder nor quieter than the others.

    Frequently asked questions

    How long does processing take?

    About a third of the length of the file. An hour of recording takes around twenty minutes; you can close the tab and come back later.

    Does it alter the voice?

    Far less than conventional noise reduction, which hollows out the highs and leaves a metallic timbre. In aggressive mode on a badly degraded recording, a slight effect can remain — try normal mode in that case.

    Do I need an account?

    No, the tool works right away. An account is only needed to lift the daily limits.

    Does the result carry a watermark?

    Never. We add no mark of any kind to the files we produce, including on the free plan.
