Every podcast episode you've ever enjoyed started as a rough recording. The version you heard was shaped by a sound editor: someone (or something) that removed dead air, trimmed rambling tangents, balanced audio levels, eliminated background noise, and arranged the recording into a listenable show.
For B2B marketers launching a podcast, understanding what audio editing involves, and who or what should handle it, is essential to making good production decisions. This guide covers what sound editing actually does, which tools handle the work, and how to think about editing as part of a larger content operation.
A sound editor works on recorded audio to prepare it for distribution. For a podcast, that typically includes:
Structural editing: Removing false starts, long pauses, off-topic tangents, repeated filler words, and any content that was cut by mutual agreement with the guest. This is the judgment-intensive part of editing. Good structural editing improves the listener experience and respects the listener's time.
Noise reduction: Removing background noise, echo, room tone, clicks, pops, and other artifacts that distract from the spoken content. Remote interview recordings frequently have noise issues because you can't control the guest's recording environment.
Level matching and normalization: Ensuring that the host and each guest are at comparable volume levels and that the overall loudness of the episode meets podcast distribution standards (typically -16 LUFS for stereo).
EQ and compression: Adjusting the frequency balance of voices to make them sound clear and full, and applying compression to reduce dynamic range so the episode sounds consistent across different listening environments.
Music and intro/outro: Inserting intro music, outro music, episode intros, and any ad reads into the correct positions with proper transitions.
Export and delivery: Outputting the final mix in the correct file format (MP3, AAC) at the correct bitrate for podcast distribution.
Done well, this process is invisible. Listeners don't notice good editing; they notice bad editing.
The terms sound editor and audio editor are often used interchangeably, but there's a distinction worth knowing.
In broadcast and film, "sound editor" refers specifically to a post-production professional who handles dialogue, effects, and music in a multi-track project. In the podcast world, the same person or role is often called an audio editor.
For this guide, we're treating them as the same thing: the person or tool responsible for taking raw recorded audio and turning it into a finished, distribution-ready episode.
There are two categories of tools used for podcast audio editing: DAWs (digital audio workstations) and podcast-specific editors.
DAWs are the professional standard for audio editing across music, broadcast, and podcast production. They offer complete control over every aspect of the audio but have steeper learning curves.
Audacity: Free and open-source. Works on Mac, Windows, and Linux. Capable for basic podcast editing, adequate noise reduction, and handles multi-track projects. Not the most intuitive interface but hard to argue with the price.
GarageBand: Free on Mac. Good for beginners and intermediate producers. Handles the full editing workflow for podcast production competently. Limited to Mac.
Reaper: Low-cost ($60 for a discounted license, $225 commercial). Extremely capable, highly customizable, and used by professional podcast editors and audio engineers. Steeper learning curve, but the depth is there for complex production.
Adobe Audition: Subscription-based. Industry-standard for broadcast audio editing. Strong noise reduction tools, good multi-track workflow, integrates with Adobe's creative suite. Appropriate for teams already in the Adobe ecosystem.
Logic Pro: $199 on Mac. Professional-grade audio production. Excellent for teams that want depth beyond GarageBand without a subscription model.
These tools sacrifice some control for significantly better ease of use and faster production workflows.
Descript: Text-based editing. You edit the transcript, and the audio updates to match. Removes words, corrects errors, and can even synthesize new audio from text using a cloned voice. Purpose-built for podcast and video workflows. Strong AI noise removal. One of the most significant shifts in podcast editing in recent years.
Alitu: Designed for podcast beginners. Automated leveling, noise removal, and chapter building. Less control than a DAW but much faster for straightforward shows.
Hindenburg Journalist: Purpose-built for spoken word. Good for teams doing interview-heavy content where the editing focus is structural rather than technical.
The audio editing landscape has changed significantly with AI tools. Several functions that required manual work and a trained ear can now be automated with high quality:
Noise removal: Tools like Adobe Podcast Enhance, Krisp, and built-in features in Descript and Riverside handle background noise removal in seconds.
Silence removal: Automated tools identify and remove long pauses, reducing editing time substantially on raw interview audio.
Leveling: AI-powered loudness normalization handles level matching automatically, producing results that previously required manual track-by-track adjustment.
Filler word removal: Automated detection and removal of "um," "uh," and similar filler is now available in several tools and works well on clean audio.
These capabilities have reduced the time required for a standard podcast episode edit and made it more accessible for non-specialists. They haven't replaced experienced human editors for complex structural editing, but they've taken a significant portion of the manual labor out of the process.
Most B2B marketing teams face a practical decision: learn to edit in-house or outsource the function.
In-house editing makes sense when: your team has existing audio production skills, your volume is low, your episodes have a simple format (e.g., solo content with minimal guests), and you have time in the workflow to dedicate to it.
Outsourced editing makes sense when: your team doesn't have production skills, you're running a regular editorial calendar, your episodes feature multiple guests with complex audio, or your team's time is better spent on strategy and content rather than post-production.
For most B2B teams, outsourcing is the correct call. Audio editing is a skilled function. An inexperienced editor working in a DAW for the first time will spend several hours producing results that an experienced editor would achieve in 30-45 minutes. That time cost compounds across every episode.
Sound editing sits in the middle of a production workflow that starts with recording and ends with distribution. The quality of the editing depends heavily on the quality of the raw recording: clean audio is significantly faster to edit than noisy, poorly-leveled audio from a problematic recording setup.
This is why professional podcast production teams typically own the full stack from recording configuration through final delivery, rather than editing in isolation. When the same team controls recording setup, editing standards, and delivery specs, quality is consistent and time spent on remediation is low.

If you're evaluating a done-for-you podcast production service, the editing function is one of the clearest quality indicators. Questions worth asking:
Specific, confident answers to these questions signal a team with real production process. Vague answers signal the opposite.
