Introduction price is available for a short time. We have harnessed Apple’s cutting-edge hardware and native programming frameworks to create an Audio Unit that is truly unparalleled. From floating-point vector registers and Metal Performance Shaders to shared memory between the Audio DSP kernel and the GPU... However — since all of this might sound a bit too technical — we didn't simply use these technologies as a means to an end; instead, we wrapped them in a musically meaningful and beautiful concept. JAX 'Walking On A Rainbow' is our answer to classic frequency analysis tools — featuring a consistently musical implementation designed for real-time processing, imbued with a certain imaginative charm. The songs we composed specifically for this purpose serve to underscore this very concept: ‘Open your mind and you'll find it's like magic. When you take a step. Oh I'm walking on a rainbow. Walking on a rainbow!’ WE ARE FRONTIERS. You can expect more to cone and - you are welcome to join us. Technical Note: The AudioUnit is smaller than 8 MB and consumes less than 1% of CPU power on an Apple M4 chip. No bloated third-party frameworks were used; this is a native development aligned as closely as possible with Apple's latest hardware (silicon).
