Free Stock Sounds for Videos, Games and Apps
The NineNifty Sound Effects Library is a free collection of royalty-free sound effects across twelve categories: UI & notifications, alarms & phones, 8-bit game sounds, sci-fi, nature & weather, household, transport, cartoon & comedy, music & instruments, impacts & whooshes, horror & cinematic and human & body.
Unlike most sound sites, nothing is streamed from a server. Each effect is synthesised live in your browser, so you can preview instantly, change the pitch to make it deeper or brighter, and download a WAV file (16-bit, 44.1 kHz) ready for Premiere Pro, DaVinci Resolve, CapCut, Audacity, Unity, Godot, PowerPoint and more.
Use them in YouTube videos, podcasts, TikToks, school projects, mobile apps, games and presentations, all free.
Frequently Asked Questions
Are these sound effects free to download?
Yes. Every sound effect in the library is free to preview and download as a WAV file, with no sign-up and no limits.
Can I use the sounds in YouTube videos, games or commercial projects?
Yes. The sounds are original and generated by our synthesizer, so you can use them in videos, podcasts, apps, games, presentations and commercial projects. Credit to NineNifty is appreciated but not required.
What format are the downloads?
Each sound downloads as an uncompressed WAV file: 16-bit PCM, 44.1 kHz, mono. WAV works in every video editor, DAW and game engine.
How are the sounds made?
Every sound is generated live in your browser by a built-in synthesizer using oscillators, filtered noise, plucked-string models and reverb. No audio files are loaded from a server, so the page is fast and private.
Can I change the pitch or volume before downloading?
Yes. Use the Pitch and Volume sliders. The download uses the same settings you hear in the preview, so you can make a sound deeper, higher, shorter or longer.
Why can't I hear anything on my iPhone?
On iPhone, web audio can be muted when the ring/silent switch is set to silent. Flip the switch to ring mode, turn up the volume and tap Play again.
Does it work on mobile and offline?
Yes. The library works on Android, iPhone, iPad and desktop browsers. Once the page has loaded, sounds are generated on your device, so it keeps working without an internet connection.
