S18E9: Getting Started ~ Your Own SFX Library with Simple Gear: iPhone + Zoom H2n

Check out how I can help You

A great way to train your ears to the nuance of sound is to collect sound. If you’re going to do this, do it with intention. Surprisingly, having a plan, a travel plan and an open mind will get you quite an array of sounds. Sounds we have all been hearing yet filtering out suddenly leap back to life.

That’s why I recommend podcasters, or podcasters to be, create their own sound effects libraries—collections of recorded sounds you can use, reuse and even license to others. The best part? You don’t need a professional studio or expensive equipment to start.

In fact, with an iPhone using the Rode Reporter app and/or a Zoom H2n handheld recorder, you’ve already got everything you need to capture clean, compelling sounds.

Here’s how to get started.

Why Build Your Own SFX Library?

Before we get to gear and process, let’s look at what makes a personal SFX library worth the effort:

Creative control: You get to capture exactly the sounds you want—tailored to your projects.
Creative Excitement: You get to “discover” sounds you didn’t know existed.
Time saved: No more scouring royalty-free sites hoping someone else recorded what you need.
Licensing potential: If you capture useful, high-quality SFX, others might pay to use them too.
Uniqueness: Your recordings are original. They can help your work stand out and you can avoid overused stock sounds.

Plus, recording sound gets you out in the world, listening deeply. It adds art and practice to the Way of The Podcast.

iPhone + Rode Reporter App: Pocket Recording Power

Don’t underestimate your phone. The iPhone, paired with the Rode Reporter app, gives you:

Uncompressed WAV recording
Simple, intuitive controls
Metadata entry (naming, notes)
Easy file export via email, cloud or AirDrop

Record with the phone mic in airplane mode for spontaneous moments

Pro tips: 1. Put the phone on a soft cloth or foam pad to avoid contact noise when capturing ambient sound.

Use an old but clean sock as a windscreen across the base of your phone.

What it’s great for:

Indoor ambiences (cafés, kitchens, bedrooms
Close-up effects (typing, taps, drawers, light switches)
On-the-go inspiration (“Hey, that fountain sounds amazing…”)

Zoom H2n: Field Recorder Workhorse

The Zoom H2n has been a budget-friendly favorite among podcasters and audio journalists for years—and for good reason.

What makes it special for SFX:

5 built-in mics with multiple recording patterns (X/Y, MS, surround)
Battery powered, compact and quiet
Records to SD card—just plug and go
Built-in gain control and limiter

Its stereo mode is perfect for ambient soundscapes, while MS (mid-side) mode lets you adjust width later in post.

What it’s great for:

Outdoor ambiences (parks, streets, beaches)
Room tone and nature beds
Capturing space, atmosphere and depth

Keep it on a tripod or mini stand for best results and use a dead cat windscreen if you’re recording outside.

I know I go on about the H2n ad infinitum but it really is a great piece of tech. Mine’s over a decade old and still going strong. The latest update after more than a decade from Zoom is the H2essential but I really can find a reason to swap out the H2n for H2e despite all the reading and listening I’ve been doing. Maybe one day, maybe. If you are about to purchase an H2 something, I’d still lean towards the “n” because of the lower price nowadays compared to the essential. As ever, the choice is yours. You can’t really go wrong with either.

Building a Habit: When, Where and What to Record

Your SFX library won’t build itself. Developing a habit of “listening with intent,” you’ll find opportunities everywhere. Just hit record! I went back and junked just about every tape from the first month of recording but I needed to record those to learn the basics of the craft and the H2n in its natural environment.

Here’s a simple framework to guide your recordings:

Environmental Ambience

Park, forest, city street, library, office
Capture long loops (2–5 minutes) at different times of day
State where you are and what time at the start of the tape and then set a timer, sit still and listen!

Action Sounds

Keys jingling, door knocks, footsteps on different surfaces
Try multiple takes from different angles
Creating sounds is fun, capturing existing sounds seems miraculous, in the beginning.

Household Sounds

Kettle boiling, toaster popping, dishwashing, fridge hum
Water is everywhere in the western world, it sounds differently in each context
Quiet, isolated environments work best here

Human Sounds

Breathing, coughing, laughter, clapping
Chatter from groups without distinct words being audible is useful too
Not always a pleasant sound but snoring is an option
Always get consent if other people are involved

Machines and Objects

Printer, coffee grinder, bicycle gears, fan oscillating
Get close but be careful with mic placement to avoid distortion
This takes practice, a contact mic may be useful in your future.

Every sound can be a future asset—just be intentional and label your recordings clearly.

Organizing Your SFX Library

A disorganized SFX library is frustrating. Get into the habit of:

Use UCS: The Universal Category System is available at this link: https://universalcategorysystem.com/
Naming files clearly: e.g. UCS CATId followed by your description ~ FEETHmn_ Footsteps_Gravel_Slow_001.wav
Storing by category: The UCS link allows you to download a folder structure matching the UCS CATId. Use that!

Tip: Save both raw and edited versions of each sound. Process, trim and fade where needed—but keep the original for flexibility.

Monetizing Your Library

Once you’ve got a few dozen high-quality sounds, you may want to share or sell them.

Some options include:

Stock platforms: Pond5, Soundsnap, AudioJungle
Patreon or Ko-fi: Share curated packs with supporters
Your own site or Gumroad store: Sell by theme (e.g. “10 Rainy Day Loops”)
Collaborations: Trade sounds with other creators to expand your collections

Make sure your sounds are properly licensed (preferably royalty-free with attribution optional) and consider bundling for value.

Use It to Feed Your Own Projects

Even if you never sell your sounds, your future self will thank you.

Having your own SFX on hand speeds up editing, enhances production quality and gives your work a personal sonic fingerprint.

For podcasters, these recordings can:

Smooth transitions between segments
Add realism to fiction or storytelling
Create an atmosphere in interviews or solo episodes
Serve as unique intro/outro elements

The more you collect, the more options you’ll have—and the less time you’ll spend searching.

A word of caution! Less is definitely more. I listen to two podcasts that have music constantly, at low level, bouncing along under the voice. It’s very annoying. It serves no purpose to enhance the narrative, it seems to be a hangover from the home video game world and judging by the ages of the voices, probably a learned behaviour. Only add SFX when they enhance the voice!!! (Rant over)

Final Thoughts: Start Small, Stay Curious

You don’t need a studio to start creating meaningful, usable sound effects.

With just your phone and the Rode Reporter app or a Zoom H2n in your bag, you can build a rich audio library that grows over time. Add a few free editing tools (like Audacity or Ocenaudio) and you’ve got everything you need to start capturing the world around you—one sound at a time.

So next time you hear a creaky gate, a distant thunder roll or the click of your coffee maker—record it.

That sound might be exactly what your next project (or someone else’s) needs.

Let’s keep the mics warm and the stories flowing. 🎙️
