VolumeHub is a macOS application that enables users to control the volume of individual applications independently. Built on Apple's native Audio Tap API, it provides per-app volume control without requiring any kernel extensions or audio drivers, ensuring compatibility and stability.

The application features per-app volume adjustment from 0-100%, live audio meters showing real-time sound visualization, and an output device picker accessible from the menu bar. It includes a 10-band per-app equalizer with 17 built-in presets and custom save options, Focus Audio that automatically ducks other apps during calls, and three view modes: Compact, Comfort, and Full density layouts.

VolumeHub operates using Apple's native Audio Tap API, eliminating the need for third-party drivers or kernel extensions. It offers Simple mode for basic volume control and Pro mode that unlocks advanced features like EQ, audio meters, Focus Audio, and device routing capabilities.

The benefits include maintaining optimal audio levels across different applications simultaneously, staying focused during calls with automatic audio ducking, and having granular control over sound output. Use cases include adjusting music volume during video calls, managing audio levels for streaming or recording, and customizing sound profiles for different applications.

Target users include macOS users who need precise audio control across multiple applications. The app is built with native SwiftUI, supports 7 languages, requires macOS 14.2 Sonoma or later, and works on both Apple Silicon and Intel Macs. It collects zero data with no analytics, telemetry, tracking, or network requests.
