Sound design basics

Creating great podcast audio isn’t just about recording voices. It’s about crafting an immersive experience that keeps listeners hooked. Let’s dive into the essentials.

Audio production toolkit

Here’s what you need to get started:

1. Microphones

Your mic is the foundation. You’ve got two main types:

Dynamic mics: Good for noisy rooms (Pyle PDMICR42SL, $79)
Condenser mics: Better sound, but pick up more noise (MXL 990, $99)

2. Headphones

Closed-back designs help you hear what you’re recording (Sony MDR7506, $98.45).

3. Recording devices

Your computer or phone works, but dedicated recorders can boost quality.

4. Software

For editing and mixing your audio.

Don’t break the bank. The Audio-Technica ATR2100x-USB ($79) is a solid budget mic. Want to step up? Try the RØDE Procaster ($166) for pro-level sound.

Sound design lingo

Get to know these terms to level up your podcast audio:

Term	What it means	Why you should care
Bit depth	Data in each audio sample	Higher = better quality. 16-bit is fine for speech
Bit rate	Data processed per second	96-160 kbps for speech, 192 kbps for music and speech
Clipping	Distortion from volume spikes	Ruins your audio. Watch those input levels!
Compression	Evens out volume	Makes soft and loud parts easier to hear
EQ	Adjusts specific frequencies	Makes voices clearer
Gain	Input volume	Set it right to avoid distortion
Noise floor	Background noise level	Lower = cleaner recordings

Master these basics, and you’ll be on your way to creating podcasts that sound amazing. The more you practice, the better you’ll get at using each element to make your show shine.

Key parts of podcast sound design

Clear voices and dialogue

Clear voices are the foundation of good podcast sound design. Here’s how to make sure your listeners catch every word:

Use quality mics and proper technique
Record in a quiet space
Cut out background noise
Boost voice frequencies with EQ
Even out volume with compression

Background sounds

Background sounds add depth to your podcast. Keep these tips in mind:

Use subtle ambient noise for atmosphere
Fade sounds smoothly
Keep levels low
Match sounds to your podcast’s vibe

Choosing and using music

Music can take your podcast to the next level. Here’s how:

Pick music that fits your show
Use short clips for intros and transitions
Fade music under dialogue
Watch your volume levels
Make sure you have proper licensing

“The only real rule is that it should sound good and engage your listener.” – Hannah Hethmon, Author at Better Lemon Creative Audio

Sound effects

Sound effects can bring your podcast to life:

Emphasize key moments
Create custom effects for a unique sound
Keep a library of common effects
Don’t go overboard – effects should enhance, not distract

Sound Effect Type	Example Use
Transition	Whoosh between segments
Emphasis	Bell sound for key points
Ambience	Ocean waves for beach scene
Foley	Footsteps, door closing

How to record good sound

Want great audio for your podcast? Here’s how to nail your setup:

Mic selection and placement

Pick a mic that works for you:

Type	Ideal For	Example	Cost
USB	Newbies	Samson Q2U	$50-$70
XLR	Pro sound	Shure SM7B	$300-$400
Lavalier	On-the-go	Rode Smartlav+	$50-$60

For the best sound:

Keep it 6-8 inches from your mouth
Angle it slightly to cut plosives
Use a boom arm to dodge desk noise

Room setup

Make your space quiet:

Pick a room away from noise
Use soft stuff to soak up sound
Skip small, empty rooms (they echo)

On a budget? Try these:

Hang blankets on walls
Put pillows around your mic
Record in a closet full of clothes

Gear essentials

You’ll need:

Audio interface (for XLR mics)
Pop filter
Headphones
Mic stand or boom arm
Recording software

“With just a basic mic and some gear, you can start recording fast.” – MusicRadar

Editing audio after recording

You’ve recorded your podcast. Now it’s time to make it shine. Here’s how to transform your raw audio into a polished podcast:

Removing noise and cleaning audio

First, cut out the junk:

Filler words
Long pauses
Mistakes
Background noise

Use a Digital Audio Workstation (DAW) to spot and remove these distractions. Some popular options:

DAW	Cost	For
Audacity	Free	Newbies
GarageBand	Free (Mac)	Mid-level
Adobe Audition	$20.99/month	Pros

Using EQ to improve voices

Equalization (EQ) shapes your audio’s frequency balance. Quick EQ tips for voices:

Cut lows: High-pass filter at 75-100 Hz removes rumble
Boost clarity: Slight increase around 3 kHz
Add air: High shelf at 8-10 kHz brightens voices

Stick to small tweaks (1-3 dB).

Balancing volume levels

Consistent volume is crucial. Here’s how:

Use compression to tame dynamic range
Normalize to match levels across files
Target -16 LUFS loudness for most platforms

Want a quick fix? Try Auphonic ($89). It levels your audio automatically.

Combining multiple audio tracks

Organize your podcast elements:

Host audio
Guest audio
Music
Sound effects

This makes it easier to adjust and apply effects.

When combining:

Use crossfades for smooth transitions
Keep timing relationships intact
Balance levels between sources

“Editing is where your story happens. It’s refining your story, crafting flow, and removing distractions.”

Adding music to podcasts

Music can make your podcast pop. It sets the mood, helps with transitions, and gives your show its own flavor. Here’s how to use it right:

Picking the right music

Match your music to your podcast’s vibe:

Sports podcast? Go for upbeat tracks.
True crime? Think eerie tunes.
Comedy? Light, playful melodies work well.

Keep it simple. Instrumental tracks often beat lyrics, which can distract listeners.

Music rights and licensing

Don’t get caught in legal trouble. Here are your options:

1. Royalty-free music

Pay once, use forever. Simple and straightforward.

2. Creative Commons

Free to use, but you’ll need to give credit.

3. Custom music

Hire a composer for a unique sound. It’ll cost you, but it’s all yours.

Music Source	Good	Not So Good
Epidemic Sound	Huge library, $9/month personal use	Pricier for commercial use
FreePD	100% free, no credit needed	Smaller selection
Custom composer	Unique to your show	Can hit your wallet hard

Blending music smoothly

Make your podcast sound pro with these tricks:

Fade music in and out slowly
Lower volume when talking (that’s “ducking”)
Use short musical breaks between segments

“Less is (usually) more. New to podcasting? Don’t go overboard with music in every episode.” – Kevin O’Connell, Product Specialist at Descript

Creating your own theme

A custom theme can make your podcast stand out. Try:

Music creation software (like GarageBand)
Hiring a freelance musician
Tweaking royalty-free tracks

Your theme should be:

Short (10-30 seconds)
Catchy
A good fit for your podcast’s style

Using sound effects well

Sound effects can spice up your podcast. But use them wisely. Here’s how:

Types of podcast sound effects

Podcasts use these sound effects:

Stingers: Short, punchy sounds (15 seconds max)
Sweepers: Brief voiceovers (under 15 seconds)
Transitions: Musical effects for segment changes
Ambient sounds: Background noises for scene-setting

When to use sound effects

Don’t overdo it. Sound effects should boost your content, not drown it out. Use them:

To set a scene (city traffic for urban stories)
For emphasis (a “ding” for key points)
To switch segments
In intros and outros

“The only real rule is that it should sound good and engage your listener.” – Hannah Hethmon, Better Lemon Creative Audio

Making your own sound effects

Want unique sounds? Create them:

Use everyday items (rustling paper for fire)
Record with your phone or portable recorder
Edit in your podcast software
Test different versions

Mixing effects with voices and music

Balance is crucial:

Lower effect volume during speech
Use audio ducking for background sounds
Place effects carefully
Test your mix on different devices

Sound Effect Source	Pros	Cons
The Free Sound Project	Free, user-uploaded	Quality varies
ZapSplat	76,000+ free sounds	Needs attribution
Soundly	Free tier available	$15/month for full access
Custom creation	Unique to your show	Takes time

Advanced sound design methods

Want to take your podcast audio to the next level? Here are some cutting-edge techniques to try:

3D and spatial audio

3D audio mimics real-world sound, making your podcast more immersive. It lets sounds come from specific directions and distances.

“I’ve always maintained that I think 3D Audio will eventually do to stereo what stereo did to mono.” – Michel Lafrance, 3D Audio Producer

To create 3D audio:

Use special software for directional sound
Apply HRTF to mimic how sound interacts with ears and head
Position sounds in a 360-degree space

“One of the best ways to know what is being recorded, is to listen in while recording.” – Anonymous

Making all episodes sound similar

Try these tricks:

Record in the same spot every time
Keep your mic 6-8 inches from your chin
Use the same voice effects each time
Make audio templates in your editing software

Axel Kacoutié from The Guardian says: “Sound design is one of the most important aspects of your podcast.”

What to Check	How to Fix It
Volume levels	Use a compressor
EQ settings	Apply the same EQ to all voices
Noise floor	Use noise reduction
Music levels	Set a standard dB for background music

Fixing common sound problems

Podcasters often face audio issues. Here’s how to spot and fix them:

Finding and fixing audio issues

Common podcast sound problems:

Background noise
Uneven volume
Poor audio quality

How to address them:

1. Identify the issue

Listen to your recording on different devices. Use headphones, speakers, and your car stereo.

2. Isolate the problem

Zoom in on problematic sections in your editing software.

3. Apply targeted fixes

Use specific tools for each issue:

Background noise? Use noise reduction plugins
Uneven volume? Apply compression or volume automation
Poor audio quality? Adjust EQ settings

Fixing uneven volume

Uneven volume makes podcasts hard to listen to. Here’s how to fix it:

Use compression to even out volume
Apply volume automation manually
Normalize audio to set all peaks to the same level

Pro tip: Aim for -16 LUFS loudness for most podcast platforms.

Getting rid of background noise

Background noise distracts listeners. Here’s how to minimize it:

1. During recording:

Use a dynamic microphone (like the Samson Q2U)
Record in a quiet space
Use sound-absorbing materials
Get close to the mic (6-8 inches)

2. In post-production:

Use noise reduction software
Apply a noise gate
Use EQ to cut problematic frequencies

“If you’re quiet, you’ll have to boost your voice up in the production and editing phase. With that comes the background noise.”

Capture high-quality audio from the start. Remember: “Garbage in, garbage out.”

Problem	Solution
Plosives	Pop filter or ERA6 Plosive Remover
Mouth noise	ERA 6 Mouth De-Clicker
Wind noise	Fuzzy pop filter or iZotope RX9 Dialogue Isolate
