Yuby is the full DJ kit: scratching, sync, and decks.
root@yuby:~# cat MANIFEST.txt
Check one, two.
Fastest and lowest latency audio engine. Same audio on macOS, iOS, Windows, Android, Linux, and web.
Intel64 + ARM64. Same features, quality, performance.
Instruments, DJ apps, realtime audio. Same library on Intel64 and ARM64. On Intel64, 2–10× faster than Superpowered on the same callback / FX chain (reverb ~10×, FFT ~2×).

No time stretch, pitch shift, or stem separation. That’s Pro / Ultra.
FLAC is new. ALAC on every OS, not just Apple.
Plug in AudioShake, Demucs, or yours. Open-source Demucs path coming out of the box.
// why move
- A real library you link — effects, player, recorder, DSP primitives in C++ / JS / WASM. No cloud round-trip, no DAW host required.
- Same kit on Intel64 and ARM64 — hard realtime on both, not best-effort media playback.
- Drop it into the audio path you already have. No new host. No new runtime.

How do you join the waitlist?
Early access is for people shipping audio in-app. Do you copy? Drop dates, SDK notes, a seat when private beta opens.
// built for these products
Building a virtual instrument?
Yuby is for synths, samplers, and playable apps that can’t afford mushy note-to-sound delay.
Building a music or creative app?
Yuby is player and FX for loopers, DJ tools, karaoke, and effects toys, without reinventing the DSP basement.
Need on-device stem separation?
Stem separation is on-device in the Player on Ultra. Plug in AudioShake, Demucs, or the one you already use.
Building VoIP or comms?
Calls, walkie-talkie, and party chat get AEC, dynamics, and clean capture/playback pipelines.
Building for VR, AR, or spatial?
Immersive apps keep audio locked to motion without torching the CPU.
Shipping embedded or automotive?
SBCs, appliances, and in-car systems get predictable realtime on ARM64, and on x64 where you still ship it.
Building a streaming player?
Yuby decodes, plays, stretches, and analyzes to build media experiences without bolting five libraries together.

Same library in C++ or JS/WASM across ship targets. No ARM-only science project. No abandoned Intel64.
// integration · C++ / JS / WASM
Yuby ships as a native C++ library — headers + lib, any C++ flavor —
or on the web as a .wasm + .js. JavaScript or TypeScript. Works in Node too.

// faq
What is Yuby?
Yuby is a high-performance C++ audio library you link, not a DAW and not a cloud API. Same library on Intel64 and ARM64 for games, virtual instruments, DJ apps, and realtime audio. In-library latency is 0 ms. Round-trip still depends on the OS and hardware audio path.
How fast is Yuby versus Superpowered on Intel64?
On Intel64, 2–10× faster than Superpowered on the same callback / FX chain (reverb ~10×, FFT ~2×). Yuby is new IP, not a fork. There is a C++ compatibility layer for an almost-drop-in Superpowered replace. Superpowered left Intel behind. Yuby puts Intel64 on par with ARM64.
Which operating systems ship the same library?
Same audio on macOS, iOS, Windows, Android, Linux, and web, in C++ or JS/WASM. iOS, iPadOS, and tvOS are ARM64. Android, macOS, Windows, and Linux ship Intel64 and ARM64. WebAssembly runs in the browser and in Node. No ARM-only science project. No abandoned Intel64.
