Podcast Audio Editing for Beginners — Get Clean, Professional Sound

Your Podcast Doesn't Need to Sound Like NPR

Let's get this out of the way: you don't need a $2,000 microphone, an acoustically treated studio, or a professional mixing engineer. A $60 USB mic in a quiet room, plus 20 minutes of basic editing, produces a podcast that sounds better than 80% of what's on Spotify.

The editing is what separates "I recorded this on my phone in a coffee shop" from "this person knows what they're doing."

The Minimum Viable Edit (15 Minutes)

If you're short on time, do just these four things:

1. Cut the bad parts — Trim the beginning, end, and any long pauses, stumbles, or tangents
2. Normalize the volume — Make it a consistent loudness throughout
3. Remove obvious noise — Apply basic noise reduction if there's a fan, hum, or hiss
4. Export correctly — MP3, 128 kbps mono or 192 kbps stereo

That's it. These four steps take a recording from "raw" to "totally listenable" in 15 minutes.

The Software: Audacity Is Enough

Audacity (free, Windows/Mac/Linux) is the de facto standard for podcast editing on a budget. It's not pretty, the interface looks like it was designed in 2003 (because it was), but it does everything you need.

Other options:

• GarageBand (free, Mac/iPhone) — Simpler interface, good enough for basic editing


• Descript (freemium) — Edit audio by editing a transcript. Revolutionary if your workflow is mostly cutting content


• Hindenburg ($12/mo) — Designed specifically for spoken-word audio


• DaVinci Resolve Fairlight (free) — If you're also editing video for YouTube episodes


• Adobe Audition ($23/mo) — Industry standard, but the cost is hard to justify for most podcasters

The Editing Process

Step 1: Import and Listen Through

Before cutting anything, listen to the entire episode with a notepad open. Mark timestamps where you need to:

• Cut a section (tangent, technical problem, "can you hear me?")


• Fix something (cough, phone notification, dog barking)


• Add something (intro music, sponsor read)

Step 2: Cut the Junk

• Trim silence from the beginning and end
• Remove full re-takes ("Actually, let me start over...")
• Cut extended "um" and "uh" chains (but leave short natural pauses — over-editing makes speech robotic)
• Remove off-topic tangents (save for outtakes if they're funny)

Step 3: Level the Audio

If one speaker is louder than another (common with remote recordings):

In Audacity: Effect → Normalize → set peak to -1 dB. Apply to each track separately first, then adjust relative levels so both speakers sound equally loud.

For more control, use Audacity's Compressor (Effect → Compressor) to reduce the dynamic range — it makes quiet parts louder and loud parts quieter, resulting in more consistent volume.

Step 4: Noise Reduction

Every recording has background noise — air conditioning, computer fans, room reverb. In Audacity:

1. Select a 2-3 second section of "silence" (where nobody is speaking, but the background noise is present)
2. Effect → Noise Reduction → "Get Noise Profile"
3. Select the entire track
4. Effect → Noise Reduction → Set reduction to 12-18 dB → OK

Don't overdo it — aggressive noise reduction makes voices sound hollow and artificial. A little background noise is natural and acceptable.

Step 5: EQ (Optional but Nice)

A simple EQ pass makes speech clearer:

• High-pass filter at 80 Hz — Removes rumble, plosives, and handling noise


• Slight boost at 2-4 kHz — Adds presence and clarity to speech


• Slight cut at 300-500 Hz — Reduces "muddiness" in male voices

In Audacity: Effect → Filter Curve EQ. Don't EQ more than ±3 dB — subtle is better.

Export Settings

Platform	Recommended Format	Bitrate	Sample Rate
Apple Podcasts	MP3	128 kbps (mono) / 192 kbps (stereo)	44.1 kHz
Spotify	MP3 or OGG	128-192 kbps	44.1 kHz
YouTube	WAV (they re-encode)	Lossless	48 kHz
Website download	MP3	128 kbps mono	44.1 kHz

Mono vs stereo: Solo podcasts should be mono (half the file size, no benefit to stereo). Interview podcasts can be stereo (left/right separation by speaker) but mono is also fine.

For quick format conversion after editing, MyPDF's Audio Converter handles WAV to MP3 with bitrate control.

Loudness Standards

Podcast platforms have loudness targets. If your podcast is too quiet or too loud relative to other shows, listeners constantly adjust their volume:

Standard	Target	Where Used
-16 LUFS	Apple Podcasts recommendation	Most common
-14 LUFS	Spotify	Slightly louder
-19 LUFS	Broadcast (EBU R128)	European standard

In Audacity, install the "Loudness Normalization" plugin to hit these targets automatically.

Common Mistakes

1. Over-editing silence — Some pauses are natural. Cutting every pause makes speech feel machine-gunned.
2. Ignoring room acoustics — Editing can't fix a highly reverberant room. Hang a blanket behind you.
3. Different mic quality per speaker — Remote interviews where one person has a $200 mic and the other uses laptop speakers sound terrible. Ask all guests to use headphones at minimum.
4. Forgetting metadata — Add title, episode number, and artwork to the MP3. Use a tag editor or your podcast host's upload form.
5. No intro/outro — Even 5 seconds of music into a brief intro makes a podcast feel professional.
