The embedded build, licensed per unit.
The same engine as the hosted API, compiled for your board and running inside your audio callback. No network round trip, no allocation, no variance between one call and the next.
What has been proven
HORN SXTN (lab build, not for sale) v1, five pitch-shifted voices plus chord detection and tracking, ran on a stock Elk Stomp development board at an average of 0.82 ms per block against a 1.333 ms deadline, worst block 1.11 ms.
- SoCSTM32MP157, dual Cortex-A7
- Clock800 MHz, performance governor
- Audio48 kHz, 64-sample buffer
- HostElk Audio OS 1.2.2, Sushi 1.3.0
- PluginHeadless JUCE 8 VST3
The desktop plugin from the same engine, THIRI VST (beta, macOS), is a VST3 tested in Ableton Live 11 and free during the beta. Join the beta.
Cortex-A7 at 800 MHz is close to the floor for this class of work. If it fits there, it fits on the part you are shipping.
How licensing works
Per unit, on the hardware you ship. The engine is delivered as a static library plus a thin integration layer for your host, with the golden-vector suite so you can prove the port is faithful on your own target rather than taking our word for it.
Evaluation builds are available for pedal makers, instrument manufacturers, and anyone putting a real-time harmony layer into hardware.
