Companion Studio · Closed Beta

The EasyDAW Engine, on your desktop.

The browser is where you create. Companion Studio is the native audio engine that unlocks low-latency recording and monitoring, professional audio interfaces, and local processing — while your project stays exactly where you left it in EasyDAW.

Release notes
  • First public Companion Studio beta release.
  • Native low-latency audio engine (PortAudio backend when installed, JS DSP fallback).
  • Automatic browser pairing via secure short-lived link + QR code.
  • Device preferences: input, output, sample rate, and buffer size persist across launches.
  • Real round-trip latency measurement via physical loopback (unfabricated).
  • Local recording cache with cloud sync queue and offline replay.
  • Live Studio Sessions, Engineering Journal, AI Mix Coach, and R2 storage all compatible.
  • Hotfix (2026-02-16): repackaged macOS + Windows bundles include the corrected VST3 backend require path so the app boots on first launch. Linux AppImages were unaffected. Re-download if you hit `Cannot find module '../vst3-host'` on start.
Known limitations
  • This beta is not code-signed. Windows SmartScreen and macOS Gatekeeper will show a first-run warning — see the installation guide.
  • VST3 hosting requires a licensed Steinberg SDK build and is disabled in this beta.
  • ASIO drivers on Windows require Steinberg's ASIO SDK; the Companion falls back to WASAPI-friendly buffer sizes.

Why am I seeing a security warning?

EasyDAW Companion Studio is currently part of our Closed Beta. As an independent software company, we've prioritized engineering, stability, and performance before purchasing Apple and Microsoft code-signing certificates.

Because of this, Windows SmartScreen and macOS Gatekeeper may display a warning the first time you install the application. These warnings are expected for unsigned beta software. Code signing and notarization are planned before public launch.

Verify the SHA-256 checksum above matches the downloaded file for extra peace of mind.
Download safely
Always download Companion Studio directly from easy-daw.com. Do not install Companion Studio from third-party websites — we don't distribute anywhere else. Future releases will always be announced through the official EasyDAW website.
