Which audio tool to choose
To edit a recording, Trim audio removes the start, the end or a section, and Merge audio joins several files into one with fades. To make a voice or a podcast sound better, use the equalizer and its presets.
For song versions there are ready-made effects: 8D, slowed + reverb, nightcore, bass booster or 432 Hz. And if you need the text of an interview or a voice note, Transcribe audio produces it with timestamps.

Frequently Asked Questions
Which audio formats are supported?
The tools accept the most common audio formats, such as MP3, WAV and M4A, and download the result as MP3 or WAV.
Are my audio files uploaded to a server?
No. The effects, trimming, merging and transcription are processed in your browser, so the file never leaves your device.
Does changing the speed change the pitch of the voice?
Not with Change speed: it speeds up or slows down from 0.25× to 3× while keeping the pitch. If you want to change the pitch without changing the speed, use Change pitch.
