Audio Freezer

Keep your DAC at its best sample rate — automatically.

A tiny macOS menu-bar app that keeps your USB DAC (or any audio device) locked to its highest supported sample rate, re-applying it the instant the device reconnects or macOS resets it.

Highlights

• Locks each device to its highest rate, or a rate you pin
• Re-applies automatically on reconnect or wake
• Shows the live format reaching your DAC, with a bit-perfect indicator
• Menu-bar only, event-driven, and fully sandboxed
