Custom Mac sounds

Your clip.
Your Mac's moment.

Most searches for custom Mac sounds land on a library of WAV files to download. That's the easy half. The hard half — the reason those files sit in a folder forever — is that macOS gives you almost nowhere to put them. There's a slot for the alert sound and that's about it.

Noisy Laptop is the other half: a menu-bar app where every Mac event has a sound menu, and your own files sit in that menu next to the built-in packs. Your voice when the Mac wakes. A four-second sample when you plug in. A sound your friend sent you, on AirPods connecting.

Before you install anything

Hear your own clip, right here

Hear your own clip first

Drop an audio file here (or pick one) to hear how it lands as a one-shot. It stays in your browser: nothing is uploaded, and nothing is saved.

m4a, mp3, wav, aiff or caf.

This is the honest test: a sound that's funny once is torture on the fortieth plug-in. Play your candidate three or four times in a row. If you're still smiling, it's a keeper.

The file you picked stays in your browser — it's read locally and never uploaded. The Mac app works the same way: your clips are copied into its own folder on your disk and go nowhere else.

The practical bits

What the app accepts, and where it puts things

No conversion step, no naming convention, no manifest to edit. Drag the file in and it's there.

File formats, storage location and length guidance for custom sounds
Question	Answer
Which file formats?	`m4a`, `mp3`, `wav`, `aiff` (and `aif`) and `caf`. Anything else is refused with a message rather than failing silently.
How does it check?	Every file is played once on import. If macOS can't decode it, nothing is copied — the whole batch is refused, so you never end up with half an import.
Where do the files go?	Copied into `~/Library/Application Support/Noisy Laptop/CustomSounds/`. The original stays wherever it was. There's a “Show in Finder” button if you'd rather manage the folder yourself.
Two files with the same name?	The second is renamed rather than overwriting the first, so nothing you've already assigned disappears.
Deleting a clip	Moves it to the Trash, not straight to oblivion. If you change your mind, it's still there.
How long should a clip be?	The app suggests under three seconds, and in practice shorter is better: well under a second for anything you hear all day, up to about two for a charger sound. Past that it stops being a cue and becomes a jingle.
Does it leave my Mac?	No. Custom clips are never uploaded, synced or transmitted. Nothing about the app phones home except Pro licence checks.

Doing it

From a file on your desktop to a sound on an event

Four steps, and the only one that takes any thought is the last one.

Step 1
Trim it first
Any audio editor, or QuickTime's trim. Cut the silence off the front — a clip that starts 200 ms late feels broken rather than late.
Step 2
Open My Sounds
The main window has a My Sounds pane. Drag your files onto it, or use “Add sounds…”. They're listed with a play button each.
Step 3
Go to Triggers
Find the event you want. Open its sound menu — your clips are listed under the packs, by file name.
Step 4
Pick it, then live with it
Set that trigger's volume too. Give it a day before deciding; most people swap their first custom sound within about an hour.

The My Sounds drop zone, listing m4a, mp3, wav, aiff and caf as the formats it takes, with a Pro badge above it — The pane tells you the formats and suggests keeping clips under three seconds. Your imported clips appear below, each with a play button.

A trigger row labelled Custom, showing that this event plays a sound of its own rather than the selected pack's — Once a trigger points at one of your clips, its row is marked “Custom” instead of “Same as pack”.

What people actually use

Ideas that survive past the first day

Grouped by the kind of thing, with the event that suits it. The short ones win.

A voice

Someone in your house saying one word. Two syllables maximum. On wake, this is the single most-loved custom sound people report — and the one most likely to make you laugh at 8am.

Good on: Mac wakes up

A meme you're not sick of yet

The ones that last are short and percussive rather than a whole punchline. If it needs three seconds of setup, it's a video, not a trigger sound.

Good on: Charger connected

Something you made

A bar from a track you're working on, a synth patch you like, a drum you recorded. Hearing your own work on a plug-in is quietly motivating.

Good on: Charger connected

A real object

Record a lighter, a stapler, a can opening, your actual front door. Real foley sits into a room better than anything synthetic.

Good on: USB device in

A game sound from something you own

A pickup, a menu blip, a save chime. Nostalgic, tiny, and already designed to be heard a thousand times without wearing out.

Good on: AirPods connected

Deliberate silence

Not everything needs a sound. Leaving an event off is a legitimate choice, and the app is built on the assumption that most of them will be.

Good on: Anything

Matching sound to moment

Which events are worth a custom clip?

All 26 of them accept one, but they don't all deserve one. A rough guide, by how often you'll hear it.

How often each kind of event fires, and what sort of custom clip suits it
Event	How often	What works
Charger connected	A few times a day	Your most indulgent clip. This is the one you'll show people.
Mac wakes up	Several times a day	Very short and warm. A voice works here; a full sting does not.
AirPods connected	Several times a day	Something tiny and distinctive, so you can tell it from the charger sound.
Screen unlocked	Several times a day	Under half a second, or skip it — it lands while you're already typing.
Battery low	Rarely, but it matters	Louder and unmistakable. This is the one place a slightly irritating sound earns its keep.
Call started	A few times a day	Short and neutral. You'll hear this one on other people's calls too.
Hourly chime	Every hour, all day	Musical, quiet, and the fastest way to discover whether you like an idea or not.

If you'd rather not build a set one file at a time, the twelve sound packs already cover the moments they do best, with the free Classic pack filling in the rest — and you can mix: a pack for everything, your own clip on the one event you care about.

Mixing

Pack clips are worth stealing for the boring events

Custom sounds aren't all-or-nothing. The usual arrangement after a week or two: your own clip on the charger, and a pack handling the eight events you don't want to think about. The events below are ones that reward a well-made short sound more than a personal one — press them and see whether you'd really do better yourself.

Custom sound questions

What people ask

Can I use my own sounds?

Yes, with Pro. The app has a My Sounds pane: drop in m4a, mp3, wav, aiff or caf files and they show up in the sound menu for any trigger, alongside the packs. Clips are copied into ~/Library/Application Support/Noisy Laptop/CustomSounds/ and never leave your Mac. More on using your own audio.

Is Noisy Laptop free?

The download is free and stays free. Free covers Charger connected and Charger disconnected with the Classic pack — no time limit, no account, no nagging. Pro is a one-time $6.99 for the rest. What's in each.

Is it a subscription?

No. Pro is $6.99 once — a personal licence for the Macs you own, with free updates for version 1. No renewal, no account.

Will this get annoying?

It's built so it doesn't. Only 13 of the 26 events are on to start with, each has a cooldown, and device and network events are ignored for a few seconds after your Mac wakes — that burst is macOS reconnecting, not you.

There's also a whole Settings section for this. Meeting mode is on out of the box and keeps the app quiet whenever your camera or microphone is in use. Quiet hours silences it between times you set. Only play through headphones does what it says. And the menu bar has a mute and a pause.

How do I uninstall it?

Quit it from the menu bar and drag Noisy Laptop out of Applications. Its settings live in your preferences and your own clips in ~/Library/Application Support/Noisy Laptop/, which you can delete as well. If you have Pro and you're moving to a different Mac, deactivate the key from the License pane first.

Which versions of macOS are supported?

macOS 14 Sonoma or later · Apple Silicon or Intel. It's a universal build, so it runs natively on Apple Silicon and on Intel Macs. There's no version for macOS 13 or earlier.
