Guide

Audio Editing Guides

Use these guides when you want more than a button-by-button walkthrough. They explain the editing decisions behind common audio tasks so you can export a cleaner file the first time.

Start with the result you need

If you need a shorter clip, start with trimming. If the file is hard to hear, start with volume. If the recording is too fast or too slow, use the speed guide. If you are comparing output choices, read the format guide before exporting.

The guides link back to the relevant tools and to related explanations, so you can move between learning and editing without landing on empty pages.
