Empower your next game or VR project with an immersive audio solution
A fully-featured, cross-platform audio engine designed with the needs of games in mind. Spatialize, occlude, reflect and drive every sound from gameplay.
Scroll to step through five of Amplitude's features, or pick one directly. Each scene is a simplified model of what the engine computes for your sources every frame.
Attenuation Models simulation on a field of dots: Fade each source with distance inside a sphere, box, capsule or cone attenuation shape.
An entity-based architecture and an optimized API let you integrate Amplitude in your game without hassle.
Assets are authored as JSON files. Write them, and let Amplitude do the rest of the magic for you.
Amplitude runs on Windows, macOS, Linux, iOS and Android, with web and console targets on the way.
Entity management and audio processing are fast: Amplitude makes extensive use of SIMD-optimized operations internally.
Amplitude is extensible. Create custom plugins to add new filters, codecs and more to the engine.
Amplitude follows the concepts of audio programming for games. Even without experience, you get started quickly.
Play physically accurate Ambisonics sources from first to third order, spatialized in real time with your HRTF asset.
Take full control of how the engine renders audio, with one pipeline you shape across all platforms.
Apply effects such as echo and gain to whole environments in real time, and build your own through plugins.
Build, package and distribute your project as a single bundle file with all your audio files included.
Create, build and release your Amplitude projects from the terminal or from a dedicated app. Pick the workflow that fits the way you work.
The official command-line tool to manage your Amplitude projects, local resources and licenses. Developed in the open, and growing in features.
The official project authoring tool for Amplitude Audio. Manage your projects, edit your assets, build and release them for your game, with all the tools in between.
Start from the C++ SDK in your own engine, or drop in an official integration for O3DE or Flax Engine. Godot and ezEngine are next.
