How to Edit Your Own Voiceover Recordings at Home

EXCERPT: A complete home editing workflow for voice actors who want clean, polished, client-ready audio without hiring an engineer, covering cleanup, processing, and delivery specs.

---

You booked the job, recorded a read you're proud of, and now there's a raw file on your desktop that sounds nothing like the spots you hear on streaming ads or audiobooks. That gap is editing, and it's a skill every home studio voice actor has to own. The good news: you don't need an engineer or expensive gear to close it. You need a repeatable process you can run on every file the same way.

Here's the workflow I teach my coaching clients for how to edit voiceover recordings at home and deliver audio that holds up next to studio work.

Pick One Editor and Learn It Cold

The software matters less than your fluency with it. Voiceover audio editing rewards muscle memory, so settle on one tool and stop shopping.

For most actors I recommend one of three:

• Audacity is free, runs on everything, and handles every task in this post. It's the best place to start if you've never edited.
• Reaper costs about $60 for a personal license and gives you a full digital audio workstation with batch processing and saved effect chains. This is what I use day to day.
• TwistedWave (Mac and iOS) is a favorite among working VO talent for its speed and clean interface.

Whatever you choose, learn the keyboard shortcuts for cut, fade, zoom, and play. You'll edit far faster, and editing is where home studio actors quietly lose hours every week.

Run a Cleanup Pass Before You Touch Any Effects

Always edit content before you process it. Trying to EQ and compress a file that still has mistakes and mouth noise in it just bakes problems into your audio.

Start by listening through once and cutting the obvious stuff: flubbed lines, false starts, the count-in where you snapped your fingers. If you recorded multiple takes of a tricky line, this is where you pick the best one and delete the rest.

Next, handle breaths. New editors tend to silence every breath, which makes a read sound robotic and unnatural. Instead, lower the volume of distracting breaths by 8 to 12 dB rather than deleting them, and only cut the loud gasps that pull focus. A natural breath before a key line is part of a believable performance.

Then deal with mouth clicks and lip smacks, those little tick sounds between words. Zoom in until you can see the click as a sharp spike, select just that spike, and apply a short fade or use your editor's repair function. RX from iZotope automates this if you do enough volume to justify the cost, but manual cleanup is completely doable on a typical 60-second script.

Set Your Noise Floor With Room Tone

A quiet background is what separates amateur uploads from professional delivery. Before noise reduction, the real fix is at the source: record in a treated space, kill your air conditioner, and silence your computer fans.

For the cleanup itself, record two or three seconds of silence at the top of every session. That's your room tone. In Audacity or Reaper, select that silent clip, sample it as your noise profile, then apply noise reduction to the whole file. Use a light touch. Reducing 6 to 10 dB usually clears hiss without that underwater, swirling artifact that comes from cranking the reduction too hard. If your read suddenly sounds like it's coming through a tin can, you've overdone it.

Process for Polish: EQ, Compression, De-Essing

This is the stage that makes a voice actor editing tutorial worth following, because it's where raw audio starts to sound finished. Apply these in order:

High-pass filter. Roll off everything below about 80 Hz. Your voice doesn't live down there, but rumble from trucks, foot stomps, and your desk does. This single move cleans up more mud than anything else.

EQ for clarity. A gentle boost of 2 to 3 dB around 3 to 5 kHz adds presence and helps consonants cut through. If your voice sounds boxy, try a small cut around 300 to 500 Hz.

Compression. Compression evens out the gap between your loud and quiet moments so the listener never has to reach for the volume knob. A ratio around 2:1 to 3:1 with a medium attack is a safe starting point for narration and commercial reads. Pull the threshold down until you see 3 to 6 dB of gain reduction on the loudest words.

De-essing. If your S sounds are harsh and sharp, add a de-esser targeting the 5 to 8 kHz range to tame them. Many condenser mics exaggerate sibilance, so this step earns its place in most chains.

Once you dial these in, save the chain as a preset. Next time you edit voiceover recordings, you load it in one click instead of rebuilding from scratch.

Master to Spec and Deliver the Right File

Clients and platforms have technical requirements, and missing them gets your files rejected no matter how good the performance is. Audible's ACX platform, for example, publishes clear audiobook standards: RMS level between -23 dB and -18 dB, peaks no higher than -3 dB, and a noise floor at -60 dB RMS or quieter. Those numbers are a useful target even for non-audiobook work.

For commercial and narration delivery, normalize your peaks to around -3 dB so the file has headroom and doesn't clip. Then export to the format the client asked for. WAV at 44.1 kHz, 16-bit is the safe default when nobody specifies; MP3 at 192 kbps or higher works when a client requests a smaller file. Name the file clearly with the project and your name, and give it one final listen start to finish on headphones before it leaves your computer.

Build the Habit, Then Build the Speed

Polished home audio comes from running the same steps in the same order every single time: cut the content, clean the noise, process for polish, master to spec, deliver. Do it ten times and it stops feeling like a chore and starts feeling automatic. That consistency is what lets you say yes to fast turnarounds without sacrificing quality.

If you want a second set of ears on your edited audio, or you'd rather have your demo produced to broadcast standard while you focus on performance, that's exactly what I help voice actors with through one-on-one coaching and demo production at votrainer.com. Send me a sample of your edited work and I'll tell you the one change that will move it closest to professional.
