SoundSource for Mac v5.3.9 is an excellent sound control software for Mac users. It provides advanced audio management solutions for applications, surpassing the basic volume control features of macOS. With a menu bar icon, users can control the volume, output devices, and audio effects for each application in real-time. It supports system-level audio enhancements and routing. It is a valuable tool for audio professionals, multimedia consumers, and those seeking high-quality audio experiences.
The interface of SoundSource is divided into three main sections: the menu bar icon, the main control window, and the floating window.
After installation, a speaker icon will appear in the top right corner of the menu bar. Clicking this icon will open a dropdown menu, which is the quickest control center.
Selecting “Open SoundSource…” from the menu bar or using a shortcut will open the main window. The window is divided into several tabs:
Clicking the pin button in the top left corner of the main window will convert it to a floating window that stays on top, making it convenient to adjust audio parameters while working on other software.
The following flow demonstrates how to complete a complex audio routing and processing task using SoundSource.
SoundSource automatically runs after startup, and the menu bar icon becomes available. For the first use, it is recommended to set up basic configurations:
Option + Command + S as a shortcut to open the main window).Assuming you want to direct the output of music playback software (such as Apple Music) to an external USB speaker, while the sound from the browser (such as Safari) is played through the built-in speakers.
You find that the voice in the video call in Safari is not clear enough, and you want to boost its volume and enhance the frequency of the human voice.
Option + Command + S) or click the “Open SoundSource…” menu bar icon.You want to add a bit of low-frequency enhancement to all system sounds and listen to the microphone input.
To facilitate quick operations during extended audio/video editing, fix the control window.
Note: SoundSource itself does not involve the “audio export” file operation; its core function is real-time routing and processing of audio streams in real-time. The “export” concept in the above process refers to the real-time output of processed audio to a specified physical device.
By combining the “Application Output Redirection” and “Effects” features, you can build advanced routing chains. For example, route the output from a DAW (digital audio workstation) software to a virtual audio driver (such as BlackHole), capture it as an “input” in SoundSource, apply a mastering effect, and finally route it to a physical output device. This achieves real-time audio processing and monitoring within the software.
SoundSource supports macOS Audio Unit (AU) plugins, significantly expanding the sound effect processing capabilities.
To save screen space:
Aside from clicking the mute button in the list, you can also hover your mouse over the application name in the menu bar and use Option + Click to quickly switch the mute state of the application.

Many gamers encounter the issue of mixed voice chat and game sound effects when playing on Mac. SoundSource can easily achieve a separation solution where game sound effects are played through the speakers, and voice chat is played through the headphones.
Step 1: Physical Connection and Device Preparation. Connect the speakers to the Mac via 3.5mm or USB, and pair the Bluetooth headphones. In the SoundSource “Devices” tab page, confirm that both are displayed as available output devices.
Step 2: Assign Game Output. Launch your game (such as Genshin Impact or League of Legends). In the SoundSource Menu Bar dropdown list, find the game process and assign it to the “External Speakers” output device.
Step 3: Assign Voice Software Output. Open Discord or QQ voice. Similarly, in the Menu Bar list, find the voice software and assign it to the “Bluetooth Headphones” output device.
Step 4: Fine-Tune Volume Balance. In the same dropdown menu, drag the volume sliders next to the game and voice software until you find a balance point where you can clearly hear your teammates’ instructions without being drowned out by the game sound effects.
This solution allows you to avoid repeatedly switching output devices in the System Preferences, ensuring that game and voice do not interfere with each other, significantly enhancing immersion.
SoundSource is not just a volume adjustment tool; it acts like a smart router on the core audio layer of macOS. It grants users absolute control over system audio streams, a feature that is missing in the original macOS.
From simple “adjust volume per application” to complex “build real-time audio processing chains,” SoundSource brings the flexibility of professional audio workstations to every Mac user’s desktop. Whether for improving gaming experience, optimizing meeting audio quality, or content creation, it is a software worth investing in.
Through this detailed installation guide, comprehensive shortcut summary table, and multiple practical cases, you should now have a comprehensive understanding of SoundSource’s powerful features.
