No. Chorus does not do per-app EQ. There is no equaliser anywhere in the app, for one app or for the whole system, and no way to boost the bass on a music app or cut the treble on a podcast. If that is specifically what you are looking for, Chorus is not the tool, and it is worth saying so plainly before you spend any time on it.
Per-app EQ means changing the tone of one app's audio separately from everything else: more bass from a music app, a flatter call, a brighter video, without touching any other sound on the Mac. It is a real, useful feature. Chorus just is not built to do it, so here is what "per-app" means inside Chorus, and where to go if EQ is what you need.
What "per-app" means in Chorus
Chorus's per-app audio feature is about where an app's sound goes and how loud it is, not what it sounds like. Pick an app, send it to a specific output device, and give it its own volume separate from every other app on the Mac. A call can sit on your headphones at a level you can hear, while music keeps playing out loud on your desk speakers. Neither app's tone changes. Chorus moves and scales the signal; it does not reshape it.
That is the whole boundary, and it holds everywhere in the app, not only for per-app audio:
- Outputs. Choose and combine the speakers and headphones already connected to your Mac.
- Inputs. Choose which microphone is active, and switch it without digging through System Settings.
- Groups. Combine several outputs into one, with a single real volume and its own balance between devices, so a quiet speaker can be brought up to meet a loud one.
- Per-app audio. Route an individual app to its own output and give it its own volume, as above.
- Keyboard shortcuts, auto-switch, volume keys and automation. Ways to control and trigger all of the above faster, not new things to control.
None of that touches frequency, tone, or dynamics. That is a deliberate line, not a gap Chorus meant to fill and missed. It keeps the app to one job: grouping and routing the audio you already have, which is also why it costs $4.99 rather than sitting closer to a full audio workstation.

If shaping the sound itself is the job, the app for that is SoundSource, from Rogue Amoeba. It groups outputs and controls apps individually the same way Chorus does, then adds a real equaliser, audio effects and Audio Unit plugin support, so you can build a processing chain over whatever your Mac is playing. It is priced for that extra capability at $49, against Chorus's $4.99. Our full comparison, Chorus vs SoundSource, covers exactly where each one wins.

Frequently asked questions
Does Chorus do per-app EQ?
No. Chorus has no equaliser for individual apps, or for anything else. It routes and sets the volume of the audio you already have; it does not change the tone or frequency balance of that audio.
If Chorus doesn't do per-app EQ, what does its per-app audio feature actually do?
It sends an individual app to a chosen output device and gives that app its own volume, separate from every other app's. A call can go to your headphones at one level while music plays through your speakers at another. Neither app's tone is touched, only where its sound goes and how loud it is.
Does Chorus have an equaliser for the whole system, if not per app?
No, Chorus has no equaliser anywhere in the app, system-wide or per app. Its job is grouping outputs, choosing inputs, and routing individual apps to devices and volumes, not shaping the sound itself.
Which Mac app should I use if I need per-app EQ?
SoundSource, from Rogue Amoeba, is the app built for that. It groups outputs and gives you per-app control the same way Chorus does, then adds a real equaliser, audio effects and Audio Unit plugin support on top. See our full comparison at Chorus vs SoundSource for the detailed breakdown of what each app covers.
Does Chorus offer any audio effects, like reverb or compression?
No. Chorus has no audio effects of any kind. It stays scoped to output grouping, input selection, and per-app output and volume, which is why it can stay a $4.99 menu-bar app rather than a full audio workstation.
