Release notes — Mac Sound Manager

0.4.0

November 3, 2026

Output routing and system audio controls

Choose a separate output device for each app, or follow the system output
Remember device selections across launches and reconnect when devices return
Switch the system output, microphone and sound-effects destination, with hardware volume controls where supported
Use a cleaner detail panel with separate Output, Equalizer and Balance sections
Open System devices from the menu-bar mixer, with the main-window section collapsed by default
Use shorter, direct device menus and smooth section expansion
Avoid redundant app-list updates and stop periodic audio discovery while the mixer is off or asleep
Keep per-app volume up to 200%, mute, ten-band EQ, saved EQ presets, balance and launch-at-login options

A universal development build for Apple Silicon and Intel Macs running macOS 14.2 or later.

Installing this development build

Open the DMG, drag Mac Sound Manager into Applications, then launch it. Allow system audio recording when prompted to enable app processing.

This build is ad-hoc signed, not Developer ID signed or notarized by Apple. If macOS blocks it, review the source before using the app-specific Open Anyway option in System Settings → Privacy & Security.

What to expect

Controls apply to whole apps, not individual browser tabs. Turning processing off restores the app’s original output while keeping its saved settings. The start of playback can be audible before processing begins.

Bluetooth, simultaneous playback through multiple physical devices, long-running clock drift and capture recovery still need broader hardware testing. This remains a development prerelease.

Installing the app

Open the DMG and drag Mac Sound Manager into Applications. Launch it and allow system audio capture when prompted.

This development build is locally signed and is not notarized by Apple. If macOS blocks it, review the source before using Open Anyway in System Settings → Privacy & Security.

Still in development

The start of playback may be audible before processing begins. Bluetooth, output-device changes and capture recovery still need hardware testing. Controls apply to whole apps, rather than individual tabs or windows.
