Make audio louderQuiet audio is boosted so that its loudest point sits just below the distortion limit. For even more, add the compressor in the editor. Remove noiseThe DeepFilterNet neural network tells speech apart from the noise of fans, air conditioning, traffic or a keyboard and quiets the background. The voice stays natural. Background musicPut the voice and the music on separate tracks. The music automatically gets quieter every time you start talking and comes back up in the pauses.

Frequently asked questions

What is LUFS?

A unit of perceived loudness under the EBU R128 standard. Unlike the peak level, it takes into account how loud the audio sounds to the ear.

Why −16 LUFS?

It’s recommended by Apple Podcasts and most podcast platforms. Spotify and YouTube use −14 LUFS – the difference is small.

How is it different from making it louder?

Boosting to the peak only deals with the loudest point. Normalization evens out how loud the files sound – better for a set of recordings.

Are my files uploaded to a server?

No. Audio and recordings are processed right in your browser and never leave your device. Only the tool itself is downloaded from our server, the same for everyone. More in the privacy policy.
