Manage Individual App Volumes on Your Mac With Third Party Solutions

MacOS does not include a built-in volume mixer that allows for individual application audio control. Unlike the Windows operating system, which features a native mixer accessible from the taskbar, Apple’s macOS is designed to manage audio at a system-wide level. When a user presses the volume keys on a MacBook or an Apple keyboard, the adjustment affects the master output of the entire machine rather than specific active programs.

To achieve granular control over sound—such as lowering the volume of a web browser while keeping a Spotify stream at full strength—users must rely on third-party software. This requirement stems from Apple’s long-standing design philosophy, which prioritizes a simplified user interface and centralizes audio management through its proprietary Core Audio framework.

The Philosophical Gap Between Windows and macOS Audio Management

The absence of a native volume mixer on macOS is a frequent point of contention for users migrating from Windows. In the Windows environment, the "Volume Mixer" has been a staple for decades, allowing users to move individual sliders for every open application. This provides a high degree of flexibility for gamers, streamers, and office workers who often juggle multiple audio sources.

Apple takes a different approach. The macOS design language assumes that if an application needs volume control, that control should exist within the application itself. For instance, YouTube, Spotify, and VLC all have internal volume sliders. Apple’s perspective is that a system-level mixer adds unnecessary complexity to the menu bar and settings, potentially leading to situations where a user cannot hear an app because its individual slider was accidentally muted deep within a sub-menu.

However, this philosophy fails in several modern scenarios. Many applications, such as Slack, Microsoft Teams, or certain web-based games, do not offer robust internal volume controls. Furthermore, managing ten different sliders across ten different app windows is significantly less efficient than having one centralized control panel in the macOS menu bar.

Essential Features to Look for in a Mac Volume Mixer

When searching for a solution to fill this functional gap, several criteria determine the quality and reliability of a third-party mixer.

First, the software must integrate seamlessly with the macOS menu bar. The primary goal of a volume mixer is quick access. If the tool requires opening a heavy application window every time an adjustment is needed, it fails to provide the convenience users expect.

Second, support for both Apple Silicon (M1, M2, M3 series) and Intel-based Macs is crucial. Because Apple changed how the system handles kernel extensions and system extensions, older audio drivers often fail on newer hardware. A reliable tool should use modern Apple-sanctioned methods for audio intercepting.

Third, look for features beyond simple volume sliders. Many top-tier mixers also offer audio routing (sending specific app audio to different output devices), per-app equalizers, and the ability to boost volume beyond the 100% hardware limit.

Professional Grade Control With SoundSource

SoundSource is widely regarded as the most polished and powerful solution for per-app audio control on macOS. Developed by Rogue Amoeba, a company with decades of experience in Mac audio software, SoundSource provides a comprehensive suite of tools packed into a compact menu bar interface.

In practical testing, SoundSource excels at handling complex audio environments. For example, a user can set their music player to output to high-quality external speakers while routing a Zoom call to a Bluetooth headset, all while muting annoying notification sounds from Safari.

One of the standout features of SoundSource is its per-app effect processing. It allows users to apply a 10-band equalizer to a specific application. If a podcast in a web browser sounds too thin, the user can boost the bass for just that browser tab without affecting the pristine audio quality of a lossless music player running in the background.

The "Magic Boost" and "Overdrive" features are also highly effective for MacBook users. If a movie file has a quiet audio track that is hard to hear over the fans or ambient noise, SoundSource can amplify the signal without introducing significant distortion. While it is a paid application, its stability on the latest versions of macOS Sonoma and Sequoia makes it a preferred choice for professionals.

Comprehensive Audio Processing With eqMac

For users who want a balance between a volume mixer and a professional-grade equalizer, eqMac is a formidable contender. It serves as an all-in-one system audio processor. While the basic version provides essential volume and balance controls, the professional tier unlocks the per-app mixer functionality that many users seek.

The user interface of eqMac is modern and highly customizable. It offers various levels of complexity, ranging from a basic 3-band EQ to an "Expert" mode with a fully parametric equalizer. In our experience, eqMac is particularly useful for users with high-end headphones who want to apply specific frequency corrections (using the built-in AutoEQ integration) while simultaneously managing the volume of different apps.

A unique advantage of eqMac is its remote control capability. Users can control the volume and EQ settings from an iOS or Android device as long as they are on the same local network. This is incredibly useful for users who use their Mac as a media center and want to adjust audio levels from across the room.

Lightweight and Open Source Options

Not every user needs a professional suite of audio effects. For those seeking a simple, free way to control app volumes, two open-source projects stand out: Background Music and FineTune.

Background Music

Background Music is a classic utility in the Mac community. Its primary function is to provide a simple list of volume sliders in the menu bar for every running application. It also includes a clever feature that automatically pauses your music player when another app starts playing audio and resumes it once the other app stops.

However, being an open-source project maintained by volunteers, Background Music can sometimes lag behind macOS updates. Installation on newer Mac hardware often requires more technical steps compared to paid alternatives. Users might encounter issues where the app needs to be reinstalled after a major OS update, but for a completely free tool, its utility is hard to beat.

FineTune

FineTune is a newer open-source project designed specifically to be a lightweight alternative to the more bloated audio suites. It focuses on doing one thing well: providing a clean interface for per-app volume and routing. In our testing, FineTune felt snappier than many other free tools, though it lacks the advanced EQ and effect features of SoundSource or eqMac.

Specialized Tools for Producers and Streamers

For a subset of users, such as podcasters and live streamers, a simple volume mixer is not enough. They need to "hijack" audio streams for recording or complex routing.

Audio Hijack

While not a traditional volume mixer for daily casual use, Audio Hijack is the ultimate tool for controlling where audio goes and how it is recorded. It uses a visual block-based interface to build audio pipelines. A user can pull audio from a browser, pass it through a noise-reduction filter, adjust its volume, and then send it to both a recording file and a streaming application like OBS.

Boom 3D

Boom 3D approaches audio control from an enhancement perspective. Its primary selling point is the 3D surround sound virtualization, which makes audio feel more immersive on standard headphones. Alongside these effects, it includes a robust volume mixer. It is an excellent choice for gamers who want to enhance the spatial awareness of their games while keeping a background Discord chat at a lower, manageable volume.

The Technical Reality of Audio Routing on Apple Silicon

Installing a volume mixer on a modern Mac involves more than just dragging an app to the Applications folder. Because these tools need to intercept the audio signal between the application and the hardware, they require deep access to the system's audio stack.

On Macs with Apple Silicon, this often necessitates the installation of a "System Extension." By default, Apple’s security policy prevents the installation of third-party extensions that modify the kernel or low-level system functions. To use tools like SoundSource or eqMac to their full potential, users often have to:

1. Shut down the Mac.
2. Hold the Power button to enter Recovery Mode.
3. Navigate to the Startup Security Utility.
4. Change the security policy to "Reduced Security" and check the box to allow "user management of kernel extensions from identified developers."

While the term "Reduced Security" sounds alarming, it is a standard procedure for professional audio and video hardware drivers. It does not leave the Mac vulnerable to general internet threats; it simply allows the user to authorize specific, digitally signed drivers from reputable developers.

How to Choose the Best Tool for Your Workflow

The "best" volume mixer depends entirely on the user's specific needs and technical comfort level.

For the Professional or Power User, SoundSource is the clear winner. The reliability, customer support, and feature density justify the price tag. It is the tool that most closely mimics the "it just works" experience that Mac users value, despite the initial security setup.

For the Audiophile, eqMac offers the best equalization tools. The ability to use professional EQ presets for specific headphone models while managing app volumes makes it a specialized tool that enhances the overall listening experience.

For the Casual User or Student, Background Music is the best starting point. If the goal is simply to turn down a loud advertisement in a browser tab without spending money, this open-source utility provides the necessary functionality without unnecessary bells and whistles.

For the Gamer, Boom 3D provides the most value. The combination of 3D spatial audio and volume mixing creates a more immersive gaming environment, allowing for better focus on in-game sounds like footsteps or distant gunfire.

Managing Audio Without Third-Party Software

While there is no system-level mixer, users can employ a few "lite" strategies to manage audio if they are unable or unwilling to install third-party drivers.

Most communication apps like Zoom, Discord, and Microsoft Teams allow users to select a specific output device in their settings. By using a cheap pair of USB headphones for calls and the built-in speakers for music, a user can physically separate the audio streams. This doesn't provide a slider, but it prevents the "audio overlap" problem.

Furthermore, many modern browsers now have a "Mute Tab" feature. By right-clicking a tab in Safari, Chrome, or Firefox, users can silence a specific website instantly. This is a binary solution (on/off) rather than a mixer, but it is often sufficient for silencing noisy social media feeds while working.

Future Outlook for macOS Audio

As macOS evolves, there is always speculation that Apple might eventually introduce a native volume mixer. With the release of each new version of macOS, Apple has been moving more settings into the "Control Center." Currently, the Control Center allows for quick switching of output devices and a master volume slider. Adding per-app sliders would be a logical next step in terms of functionality, but Apple has shown no official indication of moving in this direction.

Until then, the third-party ecosystem remains vibrant and necessary. The shift toward System Extensions has made these tools more stable and less likely to cause system crashes than the old kernel extensions of the past. For anyone who spends their day in a multi-app audio environment, investing the time or money into a dedicated volume mixer is one of the most significant quality-of-life improvements available for the Mac platform.

Summary

In summary, the lack of a native volume mixer on Mac is a design choice by Apple, not a technical limitation. By utilizing third-party applications, users can regain the granular control they might miss from other operating systems. Whether choosing a premium, feature-rich tool like SoundSource or a free, community-driven project like Background Music, the ability to balance audio levels across different applications is essential for a modern, efficient workflow.

FAQ

Is it safe to use third-party volume mixers on Mac?

Yes, as long as the software is downloaded from a reputable developer. Tools from companies like Rogue Amoeba or well-known open-source projects are signed by Apple and used by millions of professionals. However, be cautious when a tool asks for "Reduced Security" settings and ensure you understand that this is to allow the audio driver to function.

Does a volume mixer affect my Mac's performance?

Most modern volume mixers are designed to be lightweight. While some tools like Boom 3D use more CPU resources to process 3D audio effects, a simple mixer like SoundSource or FineTune typically uses less than 1% of CPU and a negligible amount of RAM.

Can I control web browser tabs individually?

Most volume mixers treat the entire browser (Safari, Chrome, etc.) as a single application. To control individual tabs, you would typically use the browser's built-in mute function. However, some advanced tools can distinguish between different audio streams if they are routed through different virtual interfaces.

Why do some apps not show up in my volume mixer?

An application will usually only appear in the mixer's list once it starts producing sound. If an app is open but silent, the mixer may hide it to keep the interface clean. Once you play a video or audio file in that app, it should appear in the menu bar list immediately.

Do these tools work with Bluetooth headphones?

Yes, almost all third-party volume mixers support Bluetooth, USB, and built-in speakers. They act as a software layer before the audio reaches the output device, so the type of hardware you use does not affect the mixer's ability to adjust app levels.
