VolumeHub: The Per-App Volume Control macOS Should Have Had Years Ago

2026-02-08 | Official Site | ProductHunt

30-Second Quick Judgment

What is it?: It lets you adjust the volume of each app individually from the macOS menu bar—turn down Spotify and turn up Zoom without digging through app settings.

Is it worth it?: If you multitask on your Mac (meetings + music + videos), the $0.99 price tag is a steal. This is a basic feature macOS has lacked for over a decade (Windows has had it since Vista). VolumeHub's biggest selling point is using Apple's native Audio Tap API—no drivers, no mess.

Three Essential Questions

Is it for me?

Target Users:

• Mac multitaskers (running meetings, music, browsers, and notifications simultaneously)
• Podcast/Video creators (needing precise control over audio sources)
• System purists (who refuse to install third-party drivers)

Am I the target?: If you're often annoyed by one app being too loud while others are too quiet, yes. If you only ever have one audio source playing, you probably don't need it.

Use Cases:

• During a Zoom call → Slack pings are too loud? Mute them individually with VolumeHub.
• Coding with lo-fi beats → A browser tab auto-plays a video? Lower its volume instantly.
• Recording a tutorial → Turn off system notifications while keeping the demo app's audio active.

Is it useful?

Is it satisfying?

The "Aha!" Moments:

• Zero Driver Install: Just download and open. Unlike SoundSource, it doesn't need the ACE driver or kernel access.
• Focus Audio: Automatically ducks other apps when you join a video call—a feature most competitors lack.
• Live Audio Meters: Seeing exactly which app is making noise is surprisingly intuitive.

For Developers

Tech Stack

How It Works

The core of VolumeHub is the Core Audio Taps API introduced in macOS 14.2 Sonoma. This allows an app to "tap" into the audio output streams of other processes after user authorization.

The Workflow: Create a CATapDescription for the target process → Call AudioHardwareCreateProcessTap → Route the tapped stream into an aggregate device → Use callbacks to process the audio buffer for volume and EQ.

Technical Hurdles: Documentation is scarce. While Apple provides basics, open-source projects like AudioCap and AudioTee are the primary references. Note: There is a known bug causing volume attenuation on multi-channel output devices, though built-in speakers and AirPods are unaffected.

Open Source Status

VolumeHub is closed source, but there are open-source alternatives:

• FineTune -- Free, open-source, and closest in features.
• Background Music -- GPLv2, features auto-pause for music, but hasn't been updated since 2022.
• BetterAudio -- Lightweight per-app volume control.

For Product Managers

Pain Point Analysis

The Core Problem: macOS lacks a system-wide volume mixer like Windows.

User Sentiment: "I switched to Mac in 2013 and my old Dell had this. It should be BASIC!" This is a long-standing grievance in the Apple Community forums. VolumeHub solves a high-frequency pain point for anyone using more than two audio-producing apps simultaneously.

Security & Privacy

• Data: 100% local, zero network requests.
• Privacy: No analytics, no telemetry, no tracking. The app literally does not connect to the internet.
• Advantage: This is a huge plus over competitors that require system-level drivers.

Conclusion

VolumeHub is the "Value King" of macOS audio control. It delivers 90% of SoundSource's power at 10% of the price, all while keeping your system clean of third-party drivers.
