A free audio editor lets you cut, trim, clean up and export recordings without a subscription. Desktop editors suit regular podcast and voiceover work, browser editors suit quick fixes on any computer, and AI tools suit cleaning up rough speech. Check the licence too, because at least one popular free version is for home use only.
Most audio editing is simple: cut the false start, remove a cough, lower a loud breath, add a fade at the end. You don't need a professional studio for any of that, and the free tools here handle it well.
Below are ten free audio editors in no particular order, sorted alphabetically, from small open-source projects to well-known names. Each description comes from the tool's own website, re-checked today. If you're recording a show, my guide to starting a podcast covers the steps before editing.
Decide whether you need a waveform editor or a multitrack studio. A waveform editor is perfect for one voice or one clip, while a multitrack studio suits interviews with music beds and several speakers.

The home-use limit in one free version
Here's the catch worth checking. NCH Software's own WavePad page says the free audio editor is available for non-commercial use only, and that the free version doesn't expire. That's fine for family videos or personal projects, but a podcast with sponsors or client work counts as commercial use.
Open-source editors don't have that restriction, so if your recordings support your business, choose one of those or upgrade to a commercial licence. Read the terms before you build a weekly workflow around any free tool.

Editing jobs and the tools that suit them
- Trimming and fades: any waveform editor does this in seconds.
- Noise and echo: AI speech tools or noise reduction effects.
- Interviews: a multitrack editor to balance two voices.
- Music beds: multitrack timelines with volume automation.
- Quick fixes on a borrowed computer: browser editors.
A simple edit for a spoken recording
- Save a copy of the raw recording before you touch it.
- Cut long pauses, false starts and off-topic tangents.
- Reduce background noise with a light touch.
- Even out the volume so quiet and loud parts sound similar.
- Add a short fade in and out, then export the final file.
Recording habits that make editing faster
- Clap at the start: it gives you a clear mark to line up separate recordings.
- Leave a few seconds of silence: noise tools learn from it.
- Restart the sentence, not the recording: it's easier to cut a clean retake.
- Note the timestamps of mistakes: you'll find them in seconds.
Voice notes can be a goldmine of content once they're cleaned up, and my piece on a voice note content pipeline shows how to turn them into posts and articles.
Finally, keep your project files and your exported audio in separate folders. When a guest asks for a correction weeks later, you'll want the editable project, not just the finished MP3.
Do you make audio editing software? Tool makers can ask to be considered for a featured place on this list.
My plain advice on free audio editors
Spend more time on the recording than the editing. A good microphone position and a quiet room will save you hours of clean-up later, and no editor can fully fix a recording made in an echoey kitchen.
And don't over-edit. Removing every breath and um makes people sound robotic, so cut the distracting bits and leave the natural rhythm alone.
Frequently asked questions
What is the best free audio editor?
It depends on the job. Open-source multitrack editors suit podcasts, while browser editors suit quick trims.
Can I use a free audio editor for my business podcast?
Yes, as long as the licence allows commercial use. Some free versions are for non-commercial use only.
Is there a free audio editor online?
Yes. Several browser editors let you trim, fade and apply effects without installing anything.
How do I remove background noise for free?
Use a noise reduction effect in a desktop editor or a browser speech tool that cleans voice recordings.
What format should I export a podcast in?
MP3 is widely used for podcasts. Keep a lossless WAV copy as your master file.
Can I edit audio on a phone?
Yes, but a computer is much easier for anything longer than a short clip.
What's the difference between destructive and non-destructive editing?
Destructive editing changes the file directly, while non-destructive editing lets you undo changes later.
Do I need plugins?
Not to start. Built-in effects cover trimming, fades, compression and basic noise reduction.
How loud should my podcast be?
Aim for consistent, comfortable volume. Many podcast hosts publish loudness guidance you can follow.
