Working with audio

Audio tools

Record, convert, trim and normalize audio directly on your device.

Are you familiar with the situation when you need to quickly record a voice note, glue parts of an audio recording or cut out an unfortunate pause, but you do not have the desire or time to install complex professional audio editors?

Our audio tools allow you to perform basic audio operations instantly and anonymously. All audio recording and processing takes place locally in your browser, protecting your conversations from network leaks.

Here you can convert tracks, speed up lectures, equalize volume, remove silence, and even visualize audio as a waveform for precise editing.
