You don't need to spend money to edit a podcast on a Mac. Several free tools can handle everything from basic trimming and noise reduction to multitrack editing and effects processing, well enough for professional-quality output.
But "free" covers a wide range. Some tools are genuinely capable. Others are stripped-down versions of paid software designed to frustrate you into upgrading. And a few are simply not built for podcast workflows.
This guide covers the best free sound editing software for Mac reviewed from a podcast production perspective, what each tool does well, where it falls short, and which type of producer it's actually suited for.
Before diving into specific tools, here's what actually matters for podcast production:
Multitrack support. If you're recording multiple speakers or layering in music and sound effects, you need a multitrack editor. Single-track tools (waveform editors) are fine for cleanup but limited for full episode production.
Noise reduction. Background noise is the enemy of professional-sounding audio. A capable noise reduction tool can save a recording made in a non-ideal environment.
Export options. You need to export MP3 (for distribution) and sometimes WAV or AIFF (for archiving). Not all free tools support all formats without plugins.
Stability and performance. A tool that crashes during a long edit session is worse than no tool at all. This matters especially on older Mac hardware.
Learning curve. For a solo podcaster or B2B marketing team handling their own production, the interface needs to be learnable without a week of tutorials.
Audacity is the default recommendation for a reason. It's genuinely full-featured, handles multitrack editing, and has one of the deepest plugin ecosystems of any free audio tool. The Mac experience has historically been rougher than Windows, but the 3.x release series improved stability significantly.
Strengths:
Limitations:
Best for: Podcasters who want a full toolkit and are willing to invest time learning the interface. It handles 90% of what a B2B podcast production workflow requires.
GarageBand comes pre-installed on every Mac and is massively underrated as a podcast tool. It's technically a music production app, but it works well for recorded audio, especially if you're doing interviews with clean source audio.
Strengths:
Limitations:
Best for: Mac users who want a polished experience out of the box. Great for beginners. Handles interview-style podcasts well if the source audio is clean.
ocenaudio is a lightweight, single-track waveform editor that's particularly strong on Mac. It's not a full DAW, but for simple podcast editing, trimming, leveling, basic noise reduction, it's fast and reliable.
Strengths:
Limitations:
Best for: Producers who need to clean up a single-track recording quickly. Works well as a companion to a more complex tool.
Reaper isn't free, but it deserves mention because the license is $60 (discounted) and the trial version has no functional limitations; it just reminds you to buy it. For B2B teams on a budget, Reaper is effectively free until you're ready to pay.
Strengths:
Limitations:
Best for: Serious podcast producers who want a pro-grade tool without a subscription. Many professional podcast editors use Reaper as their primary DAW.
Tenacity is an open-source fork of Audacity that was created in response to privacy concerns about Audacity's data telemetry. Functionally nearly identical, with a slightly cleaner interface and more active community development.
Strengths:
Limitations:
Best for: Anyone who wants Audacity's capability without the privacy questions.

The honest answer: most professional B2B podcast production teams don't rely exclusively on free tools. They use Adobe Audition, Logic Pro, or Hindenburg, paid tools built for high-volume, consistent-quality production.
But free tools absolutely have a place:
If you're evaluating whether to handle production in-house or outsource, free software is one factor, but it's not the most important one. The bigger question is whether your team has the time and expertise to use these tools to produce consistently high-quality output. For more on the tradeoffs, see our guide to launching and producing a company podcast.
Free audio editing software handles production, but for B2B teams, editing is just one piece. Once your episode is produced, you also need:
These steps are often handled by separate tools or services, especially for teams running multiple shows or high-volume content programs. For a broader look at the toolchain, see our overview of B2B podcast content strategy.
For Mac-based podcast production, Audacity is the most capable free option. GarageBand is the best starting point for beginners. Reaper is the best path to a professional-grade workflow without committing to a subscription.
None of these tools will hold you back if you know how to use them. The constraint isn't the software; it's the time and expertise to use it well. If you're managing a B2B podcast program alongside other marketing responsibilities, that's the tradeoff worth thinking through.
