DJ apps
Scratching, sync, decks, the full DJ kit. Built for a DJ app.

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×).

Lowest-latency paths on x86 and ARM64 — for vibecoders and hardcore audio devs alike
OS audio stacks are a maze. You want interactive sound in the app now — not three months of callback spaghetti, unexplained glitches, and “works on my phone.” Yuby is the C++ / JavaScript / WebAssembly library that keeps the buffer honest.
One API. First-class Intel64 and ARM64. Plus WebAssembly in the browser. Harder, better, faster, stronger when every sample counts.

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.

Virtual instruments
Synths, samplers, and playable apps that can’t afford mushy note-to-sound delay.
Music & creative apps
Loopers, DJ tools, karaoke, effects toys — player + FX without reinventing the DSP basement.
Stem separation
On-device. Plug in AudioShake, Demucs, or the one you already use. Ultra, in the Player.
VoIP & comms
Calls, walkie-talkie, party chat — AEC, dynamics, and clean capture/playback pipelines.
VR / AR / spatial
Immersive apps where audio has to stay locked to motion without torching the CPU.
Embedded & automotive
SBCs, appliances, in-car systems — predictable realtime on ARM64 (and x64 where you still ship it).
Streaming & players
Decode, play, stretch, analyze — 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.
Xcode, Visual Studio/MSVC, Android NDK, Clang, GCC.
