Free cash register sounds, and one for every sale Here are the two cash-register sounds I put in Slap Alert 1.6.4. Press play. Wow, that bell! They're real recordings, not synth beeps, and they're CC0, so download them and use them in your video, game or slideshow. No sign-up, no strings. If you sell online, there's a second option: hear one every time you make a sale. Slap Alert is my little Mac app. A pixel monkey swings down and slaps a sticky note on your screen with who paid and how much, plus the sound you pick. These two recordings are in the slapalert.com download. ## Play the cha-ching sound A drawer rattle, then a bright bell ching. 1.2 seconds.

It's a sharp crack and a low thump, and the app picks from four slightly different takes. You hear it when the monkey slaps the note. This button plays one of them. Slap is made by the app itself, so it's here to hear, not to download. Play Sound description: a sharp crack and a low thump. About 0.2 seconds, no speech. The Slap Alert Connect your sales window with a yellow New sale! test note for Test Monkey (Banana Co.), $49.00, slapped on top ## Pop and Off: the quiet options Pop is the macOS system Pop sound. You already have it. On a Mac, open System Settings → Sound and pick Pop under Alert sound to hear it. I don't host that file. Off is no sound at all. The note still slaps. ## Can I download these sounds for free? Yes. Cha-ching and Register are [CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/), so download the MP3 or the WAV above and use them. No sign-up. The originals are on Freesound: [Cash Register Fake.wav by CapsLok](https://freesound.org/people/CapsLok/sounds/184438/) and [Vintage cash register by Tompalompa](https://freesound.org/people/Tompalompa/sounds/475915/). Slap is generated in my app, so it's here to hear, not to download. Pop is a macOS system sound, so that one is a description only. ## Can I use them in a video, game or app? Yes. CC0 means no permission and no credit are required. A credit to the original recordists is a nice touch. The licence text is the [CC0 deed](https://creativecommons.org/publicdomain/zero/1.0/). ## How do I hear a cha-ching every time I make a sale? Setup takes about two minutes. Connect [Stripe](https://slapalert.com/stripe), [Paddle](https://slapalert.com/paddle), [Polar](https://slapalert.com/polar), [Dodo Payments](https://slapalert.com/dodo), [RevenueCat](https://slapalert.com/revenuecat) or [Shopify](https://slapalert.com/shopify), or the [App Store](https://slapalert.com/app-store) as one note each morning. Then choose Sound → Cha-ching. Only sales made after you connect get a slap. More on the Stripe sound is in [Stripe payment notification sound on your Mac](https://slapalert.com/blog/stripe-payment-notification-sound). ## Can I get a cha-ching for Etsy or eBay sales? No. Slap Alert doesn't connect to Etsy or eBay, and it doesn't connect to Gumroad or PayPal. [Shopify](https://slapalert.com/shopify) does. The free JSON Inbox can take a sale from your own script, but I don't have an Etsy or eBay recipe. ## Questions Is the volume adjustable? Not in the app. Playback is fixed at 0.85, so use your Mac's volume. Which sound is the default? Slap. Cha-ching, Register, Pop and Off are the other choices, in the slapalert.com download from 1.6.4. ## Get Slap Alert Slap Alert is a one-time purchase, currently US$19, with a 7-day free trial.
