Elk Audio OS is a fully-featured embedded Linux distribution optimized for low-latency audio applications. It is currently used by companies making professional audio products, audio enthusiasts building their own devices, and serves as the core of Elk's own Elk Live online music collaboration tool.
The core audio plugin host, Sushi, is also available as an independent application for macOS and Linux, and can be used as a flexible programming environment for building other kind of audio applications for those platforms.
Since the release of Elk Audio OS 1.0, we are focusing on giving open support only for Sushi and for the image running on Raspberry Pi 4 with HiFiBerry and the RPi audio hats. The previous documentation on other development kits and features (e.g. the Elk Pi board) is now available under the "Legacy Documentation" section in this page.
