Independent volume per app
Chrome too loud over Spotify? Pull its slider down. Zoundry detects every app playing audio: Chrome, Safari, Spotify, Zoom, Discord. Each gets its own slider. No setup required.

macOS native
macOS gives you one volume slider.
Zoundry gives you one for every app.
Apple's macOS lets you pick a single output device at a time. Switch to your AirPods and everything follows your Zoom call, your Spotify playlist, your YouTube tab in Chrome. There's no native way to lower just one app, or send a single app to a different output.
Zoundry is the per-application volume control for Mac that should have shipped with macOS.
Features
Everything your Mac's audio was missing
Route each app to a different output
This is the feature macOS has never offered. Send Chrome to your AirPods Pro, Safari to your headphones, and Spotify to your MacBook speakers, all at the same time.
Every audio device in one menu
AirPods, MacBook speakers, Bluetooth headphones, USB-C headsets, external DACs: all in one panel. Switch your default output with a single click. Skip System Settings entirely.
Lives quietly in your menu bar
One click to open, one click to close. No dock icon. No floating windows. No distractions. Zoundry stays out of your way until you need it, right where a Mac utility should live.
Per-app EQ and L/R balance
Shape bass, mid, and treble for each app individually, and nudge its stereo balance left or right, with a snap back to center. Dial in Music without touching Zoom.
Save and switch sound presets
Save any EQ setup as a preset, like Bass Boost or Vocal Boost, then switch between them per app in one tap. Build your own from scratch, or start from the built-ins.
Control every microphone, per device
Built-in mic, USB interface, or a virtual input like a stream mixer: pick and adjust any of them from the same panel, no more digging through System Settings.
Native, lightweight, Apple Silicon first
Built natively for macOS Tahoe on Apple Silicon. Minimal CPU, minimal memory. Maximum control.
Automate it with Shortcuts & scripting
Set or check any app's volume from Siri, the Shortcuts app, Alfred, Raycast, or Terminal. No setup, no toggle, it just works.

Remote workers on a call in one app while music plays quietly on a different device.

Content creators and editors who need reference audio on studio monitors and system alerts on headphones.
