Noise Gate & De-Esser

Remove background noise and soften harsh vocal frequencies instantly.

Online Noise Gate & De-Esser Tool

Enhance your voice recordings by eliminating unwanted room noise and taming sharp "S" and "Sh" sounds.

What is it?

This is an advanced audio processing utility combining two powerful studio tools. The Noise Gate automatically mutes the track when the volume drops below a certain level, effectively removing background hiss, fans, or room echo when you stop speaking. The De-Esser specifically targets and reduces harsh high-frequency sounds (sibilance) in vocals. Our tool supports popular audio formats including .mp3, .wav, .ogg, .m4a, .aac, and .flac. Everything is processed securely in your browser's memory without uploading files to any external server.

How to use it?

Upload your audio file and start playback using the preview button. Adjust the Noise Gate Threshold so that it cuts out background noise during silent parts but keeps your actual voice clear. Then, tweak the De-Esser Frequency and Threshold to smooth out piercing high-frequency sounds. Once you find the perfect balance, click the export button to download a polished .wav file.

Who uses this tool?

Podcasters, streamers, YouTubers, and vocalists use this tool to clean up their microphone recordings, delivering a professional, broadcast-ready sound free from distractions and ear-piercing peaks.
