AudioLaunch — mobile music studio + Resonara

A mobile music studio with a custom native Rust audio engine, plus Resonara: a gamified world that teaches sound design while you play. Eight years solo-built — from the first concept in 2018 to today's public open beta. Until recently this listed here under Stealth; the name is off now.

Two sides

Studio is the serious side: multi-track recording up to 24-bit/96kHz, live editing, FX chain, MIDI, sample import, synths, mixer, master chain. Runs on a custom native Rust audio engine for low-latency real-time DSP on Android (NDK + JNI + React Native FFI).

Resonara is the other side: a story-driven world that teaches sound design through missions. Vibes, worlds, level pacing, missions and skills as progression mechanics — the play is the curriculum.

Eight years, one problem space

Year	Phase
2018	Concept + vision
2020	First sketches
2022	Mobile pivot
2024	Production tier
Now	Live · public open beta

Three concept pivots and several rebuilt iterations happened in between. Not a straight line, but a consistent thread: the same problem, held for eight years.

Stack

Audio engine

Rust, FFI-bridged via JNI on Android. Custom DSP graph, real-time scheduler, sample-accurate timing.

App shell

React Native (Expo), TypeScript, Kotlin native modules

Cloud

Supabase EU (auth, storage, postgres), Vercel (web)

Privacy

recordings stay on-device by default; cloud storage and publishing are EU-hosted and only happen after the user explicitly opts in

Pricing

Tier	What
Free	Full Studio creation tools (recording, multi-track, FX, MIDI, sample import) — never credit-taxed
Founder	€139 one-time, available during the entire beta window (≥12 months from Play Store launch). Founder badge, beta-window access, never-expiring
Pro	Subscription, post public launch

Status

Live in public open beta at audio-launch.com — play in the browser or grab the Android build. Not yet on the regular Play Store listing; that's the next step. Build philosophy: SOTA-or-cut — features that can't ship at SOTA quality are cut from v1.0 rather than shipped half-baked.

Sister project: audiolab.tools, a public browser-side audio toolkit — a separate product, also by me.
