VolumeHub is a macOS application that enables per-app volume control, addressing a long-standing limitation of the operating system. It allows users to adjust each application's volume independently from 0-100% directly from the menu bar, eliminating the need to navigate through System Settings.

The application features per-app volume sliders, live audio meters showing real-time audio output visualization, an output device picker for quick audio switching, and three view modes (Compact, Comfort, and Full) to match different workflows. It includes a 10-band per-app equalizer with 17 built-in presets, Focus Audio that automatically ducks other apps during calls, and both Simple and Pro modes for different user needs.

VolumeHub is built on Apple's native Audio Tap API, which means it requires no kernel extensions, audio drivers, or background processes. This native integration ensures compatibility and stability while maintaining system security.

The primary benefit is precise audio control across multiple applications simultaneously, such as turning down music while keeping communication apps loud during calls. It helps users stay focused by automatically managing audio levels during important activities.

The application targets macOS users who need granular control over their audio experience, particularly those who frequently use multiple audio applications concurrently. It's built with SwiftUI for native macOS integration and supports 7 languages while collecting zero user data.
