Frequently Asked Questions

Where is the app window?

VolMix lives in the menu bar and does not show a Dock icon. Click its slider icon at the top-right of your screen to open the mixer. The gear button opens Preferences; the power button quits VolMix.

How do I get started?
  1. Play ordinary, unprotected audio in an app and open VolMix from the menu bar.
  2. Lower that app's slider below 100% or click its mute button.
  3. Allow the system-audio capture permission requested by macOS. Audio processing stays on your Mac.
Why is an app missing or not adjustable?

Start playback so macOS exposes its audio process. Protected audio, unusual routing, and some output devices may not support per-app control. Try an unprotected local file with the Mac's built-in speakers to check your setup. VolMix controls apps, not individual browser tabs, and does not amplify audio above 100%.

What if I denied audio permission?

Open System Settings → Privacy & Security and locate the screen/system-audio recording permission section; the name varies with macOS. Enable VolMix and relaunch it if macOS requests this. The permission is used to adjust app audio, not to capture screen images or microphone input.

What if an app becomes silent or sounds distorted?

Return its VolMix slider to 100% and unmute both the app and the master output. Confirm the source app is playing and the expected output device is selected. If the problem continues, quit VolMix using its power button to release its audio processing, then check playback again. Send the app, device, macOS version, and any displayed error to support.

Can I choose an output device for each app?

Yes, since VolMix 1.5. Click the output icon on an app’s row and pick a device; choose “Follow System Default” to undo. The system default output stays unchanged, and if a device disconnects, that app falls back to the default output. Scenes remember each app’s output device. Master volume and mute depend on the device's software-control support; some digital outputs require volume adjustment on the hardware.

Why does Safari appear as a single row?

Since VolMix 1.5, sound from Safari and from web content embedded in apps appears as one “Safari & Embedded Web Audio” row, which you can hide in Preferences. You can also make the panel wider in Preferences → General: Standard, Wide or Wider.

How do I change the language?

Open Preferences → General and choose English, 简体中文, or Follow System. The app changes language immediately and remembers your choice. This website has its own language selector above.

Is there a subscription? How do I restore purchases?

No subscription is required. VolMix offers a 7-day free trial, then you buy once:

  • 7-day free trial: Claim a 7-day free trial to experience all features. There is no subscription and no automatic recurring charge.
  • Buy once: After the trial, a single in-app purchase unlocks all features, including all 1.x updates. No subscription, no account required.
  • Restore purchases: When reinstalling or moving to another Mac, log in with the Apple Account used for the original purchase, open the “Trial & Purchase” panel in VolMix, and click Restore purchases. Existing users who purchased VolMix previously also retain full access without paying again.
Does VolMix record or upload audio?

No. Application audio is processed temporarily in memory on your Mac. VolMix does not save recordings or upload audio. See the VolMix Privacy Policy for local settings, Apple services, support emails, and website information.

How does VolMix compare to SoundSource or Sound Control?

Tools like SoundSource offer more features but require installing a third-party audio driver plug-in (ACE) and cost more. VolMix is built on native macOS audio APIs, needs no driver, runs in the sandbox, and is a one-time purchase with no subscription — ideal if you just want per-app volume and output device control.
