Overview

Editing without a desktop DAW

Trim narration, concatenate interview segments, split long captures, tame file size before email, bounce between WAV and compressed formats, and even out perceived loudness—patterns mirror our image and PDF hubs so onboarding stays trivial.

Processing targets FFmpeg WASM in modern Chromium-class browsers; very large originals should be shortened upstream when RAM is tight.

Pair with video when you remix

Strip troublesome soundtracks from video clips on the Video hub, finesse WAV or MP3 here, then remux downstream in tools your team already trusts.

Treat Master recordings as authoritative—heavy lossy chains stack artifacts—and keep legal clearance for samples you concatenate.

Using this tool

Audio Tools uses the same Merge AI Audio Tools pattern: add files, adjust the settings that matter for your export, then download results. Placement of controls matches our other utilities so screenshots and onboarding docs stay consistent.

Review the output before you send it externally. When you need a follow-up step—compress after convert, merge after split, run an ATS check on a résumé—use the related links on this page instead of searching for another vendor.

Frequently asked questions

Will every codec export on my device?
Depends on the bundled WASM codecs; WAV is the most reliable fallback. Try Convert if one format errors.
Does Merge AI keep my uploads?
Flows aim for browser-side work; confirm policy on shared workstations.
