Trueness lineHeadphone correction + crossfeedShipping

Level

Hear your headphones honestly.

Flattens a headphone's measured response by inverting its curve, then adds Bauer-style crossfeed so a mix translates the way speakers would. The signal comes out measurably corrected, honest before anything else.

We’ll email you the download, and let you know when this beta updates. Unsubscribe any time; nothing is shared.

Installing the beta

This beta isn’t notarized by Apple yet, so macOS shows a one-time “unidentified developer” warning the first time you open the installer. It’s safe to allow. Here’s how:

  • macOS 15 (Sequoia) and later: double-click the downloaded .pkg. When macOS blocks it, open System Settings → Privacy & Security, scroll down, and click Open Anyway.
  • macOS 14 and earlier: right-click the .pkgOpenOpen.

Installs to /Library/Audio/Plug-Ins/Components/Level.component (AU), …/VST3/Level.vst3 (VST3), and /Applications/Level.app (Standalone). Relaunch your DAW afterward so it rescans. A notarized build with no warning ships once the Warren Labs developer account is approved.

Don’t see your headphones?

The library grows by request. Tell me the make + model and I’ll add a measured correction curve.
