VolumeHub

VolumeHub's Live Audio Meters bring real-time visualization of each app's audio output, showing dynamic level bars that indicate which applications are actively playing sound and how loud they are. This feedback is essential for quickly identifying unexpected noise sources or confirming that an app is muted. The meters respond instantly, reflecting even transient sounds, and work alongside the per-app sliders to give you full awareness of your audio landscape. Complementing this is the Output Device Picker, a one-click menu bar control that lets you switch between audio interfaces—internal speakers, headphones, USB DACs, or Bluetooth devices—without navigating System Settings. Instead of interrupting your flow to dive into Sound preferences, you simply select your desired output from the VolumeHub dropdown. For users who frequently move between a desk setup and mobile work, this fast routing saves time and eliminates the frustration of lost audio when connecting or disconnecting peripherals. Together, these features provide a complete monitoring and routing suite that keeps you in the loop and in control.

Beyond basic volume, VolumeHub offers a Per-App Equalizer with a 10-band graphic EQ and 17 built-in presets such as Rock, Jazz, or Vocal Boost, plus the ability to create and save your own custom curves. This means you can shape the tonal character of each app individually—boost bass in a music player, enhance clarity for a conferencing tool, or tame harshness in a video. The Focus Audio feature takes automation further by automatically ducking the volume of other apps when a call or a designated focus source is active. For instance, when you join a Zoom meeting, all non-essential audio dims to a preset level, ensuring you stay immersed without touching a slider. VolumeHub also caters to different user maturity with Simple and Pro modes. Simple mode offers a clutter-free volume-only interface, while Pro mode unlocks EQ, meters, Focus Audio, and device routing. This tiered approach welcomes casual users while giving power users the full toolkit they demand.

VolumeHub is implemented as a native SwiftUI app that lives in your menu bar, appearing as a compact icon that expands into a popover window. It does not run background daemons; all processing happens on demand and uses Apple's Audio Tap API to intercept and adjust audio streams at the system level without injecting any code into apps. The app supports three view densities—Compact, Comfort, and Full—so you can tailor the interface to your screen real estate and preference. Compact mode shows only slider handles, Comfort adds app names, and Full reveals the entire control suite including EQ and meters. Switching between modes is instant and remembers your layout. Crucially, VolumeHub collects zero data: no analytics, no telemetry, no tracking, and no third-party SDKs. It never makes a network request, ensuring your audio habits remain completely private. This privacy-first, performance-native design represents a clean break from bloated audio managers that rely on kernel extensions or cloud connectivity.

Consider a remote worker named Alex who starts the day with a video standup. While presenting, background music from Spotify threatens to overpower his voice. With VolumeHub, he simply opens the menu bar and drags Spotify's slider down to 20%, keeping the meeting crisp. Later, as a designer, he switches to reference tracks for inspiration, using the Full mode EQ to tweak the sound signature of his reference app. When a client call comes in, Focus Audio ducks all music automatically, letting him concentrate on the conversation without scrambling. A musician uses VolumeHub to separately adjust the levels of a metronome app and a guitar amp simulator, routing both through an external audio interface via the output picker. Each scenario illustrates how precise, per-app audio control eliminates distractions and streamlines multitasking. Users report saving minutes daily by avoiding system setting dives and feeling more in control of their digital workspace.

VolumeHub is made for anyone on macOS who manages multiple audio sources: remote workers juggling Zoom and media, content creators who need reference tracks, musicians with audio production apps, designers, and privacy-focused users who refuse to trade data for convenience. It runs on macOS 14.2 Sonoma and later, working seamlessly on both Apple Silicon and Intel Macs, with no architecture-specific limitations. The app is distributed exclusively through the Mac App Store, ensuring secure installation and auto-updates. While pricing details are not specified on the site, the download is available to all compatible Macs. In a market filled with intrusive or legacy-dependent audio tools, VolumeHub stands out by delivering per-app volume control Mac users have long desired, packaged in a clean, native interface that respects your privacy and system stability. It's the missing piece of macOS audio management that finally gives every app its own voice.
