Complete Guide to Podcast Audio Editing!

Thinking about starting a podcast? When you hear "audio editing," does it sound complicated and time-consuming?

Podcasting is like internet radio that anyone can listen to easily on smartphones or computers. With the rise of individual creators in recent years, it's really gaining attention.

But here's the thing – no matter how amazing your content is, poor audio quality will drive listeners away. The main purpose of audio editing is actually to reduce "ear stress" for your listeners.

In this article, I'll walk you through the editing tasks and efficient workflows you need to create high-quality audio that keeps your listeners comfortable and engaged.

Why is Audio Editing So Important? Let's Think from the Listener's Perspective

Audio editing isn't just about making things sound better – it's actually the deciding factor in whether listeners can comfortably enjoy your show.

Most podcast listeners are multitasking – doing chores, driving, walking, or working on hobbies while listening. When the volume is too low or there's distracting noise, they'll think "this is hard to listen to" or "this is tiring" and eventually tune out.

For example, if you're targeting people who listen to podcasts before bed, you want to create a soothing, relaxing audio environment. Listeners come with curiosity – they want to "learn more" and "gain new perspectives" – so audio quality is crucial for meeting those expectations.

Unlike video content, audio is a medium where people understand by imagining what they hear. That's why it creates closer connections with listeners and builds deeper relationships. Providing easy-to-listen audio strengthens that bond even more.

6 Key Points for Editing

Audio editing mainly involves these 6 points. Just being mindful of these will make your podcast much more listenable:

1. Low-frequency Cut (High-pass Filter)
   • Even though we can't hear them, low-frequency noise actually puts strain on our ears. Cutting these frequencies makes the audio much clearer.
2. Preventing Audio Clipping
   • When volume is too high and creates that harsh "crackling" distortion, it's extremely unpleasant. Preventing this dramatically improves listening comfort.
3. Environmental Noise Removal
   • Air conditioning hum, traffic noise, room echo... these background noises from your recording environment distract listeners. Using a dynamic microphone can also help reduce noise.
4. Volume Consistency (Loudness Normalization)
   • When volume varies throughout an episode, listeners have to constantly adjust their volume controls, which creates stress. Major platforms like Spotify, Apple Podcasts, and Amazon Music have recommended loudness standards, so it's good to match those.
5. Sibilance Reduction
   • Sometimes "S" and "Z" sounds become harsh "shh" sounds that can be quite unpleasant for some people. These need appropriate treatment.
6. Lip Noise Removal
   • Those "smacking" mouth sounds are pretty distracting for listeners. They're hard to avoid during recording, so they need to be removed in editing. Plosive sounds (P, B sounds) can be reduced with a pop filter.

The Reality of Editing Time

When you actually start editing, expect it to take 2-3 times longer than your audio length. For a 30-minute show, you're looking at 1-1.5 hours of editing.

Of course, careful editing is important. But if you spend too much time on it, you'll get burned out and might think "editing is such a pain, maybe I should quit podcasting..." It's really a shame when someone stops podcasting just because editing becomes too burdensome.

For sustainable podcasting, you need to balance "audio quality" and "editing time." Many people want to spend more time on content and planning, so it makes sense to make editing as efficient as possible.

Audio Editing and Tools

Doing all this editing work manually every time is tough, but with the right tools and methods, even beginners can efficiently create high-quality audio.

1. Software for Recording and Editing

For smooth podcast production, I recommend tools that handle everything from recording to editing in one place.

• Logic Pro
  For serious editing and detailed sound design, Logic Pro is perfect. It's a paid Mac-only software used by professionals, with tons of features. Great for those who want to be really particular about audio quality and finishing.

• GarageBand
  If you're using Mac or iOS devices, why not start with GarageBand? It's free but can handle everything from recording to editing to adding background music. You might need some time to get used to the interface, but there are tons of tutorials online. When you're ready for more advanced features, upgrading to Logic Pro is easy.

2. Editing Workflow

1. Recording/Import: Import audio into your software or record directly
2. Cutting: Remove unwanted sections
3. Noise Processing: Use AI noise reduction and echo removal for problematic sounds
4. Mixing: Balance volume levels across different audio tracks
5. Export: Create distribution files in MP3 or M4A format

For high-quality content, professional software editing is really essential.
