In macOS
macOS has no per-app volume. Every app shares one volume level and one output device, so a separate app is needed. The table below compares the most common ones.
Comparison

|---|---|---|---|---|---|
| Tuno | Free | Yes, up to 200% | Yes | Yes | No |
| SoundSource | Paid (free trial) | Yes | Yes | Yes, with effects | Yes |
| Background Music | Free, open source | Yes | No | No | Yes |
| eqMac | Free / Pro | Pro only | No | Yes | Yes |

Frequently asked questions
Which one should I choose?
For per-app volume, per-app output and an equalizer at no cost, Tuno. For professional audio effects and Audio Unit plug-ins, SoundSource. On an Intel Mac or a macOS version older than 15, Background Music or eqMac, because Tuno needs macOS 15 and Apple silicon.
Why does it matter whether an app installs a driver?
Driver-based apps add a virtual audio device to your Mac. Tuno uses the audio capture built into macOS 15 instead, so nothing extra is installed and removing it is just deleting the app.
What does Tuno not do?
It doesn’t host Audio Unit plug-ins and it runs only on Apple silicon Macs with macOS 15 or later.
