Most of the best Mac audio apps are one-time purchases, not subscriptions. The tools that control per-app volume, EQ and routing — SoundSource, Loopback, Audio Hijack, Fader, and the free open-source options — all run on your own Mac, so you pay once and keep them. Subscriptions show up only where a tool leans on the cloud or AI, like Krisp's noise removal. For the everyday job of making one app quieter than another, you never need to rent software.
This is worth saying plainly, because "there's an app for that" on the Mac increasingly means "there's a monthly fee for that." Audio is one of the last corners that mostly resisted. If you've been putting off fixing your sound setup because you assumed it meant another line item on your card, the good news is that the category is unusually honest about pricing. Here's who charges what, and the one place a subscription is genuinely the right call.
Why Mac audio stayed subscription-free
Subscriptions make sense when the maker has a recurring cost to cover — servers running your requests, a model being retrained, storage holding your files. Per-app volume and routing have none of that. The work happens entirely on your Mac's own audio hardware. There's no server in the loop, nothing to host, nothing that costs the developer money while you use it. So the people who build these tools have no reason to rent them to you, and historically they haven't.
Rogue Amoeba, the studio behind SoundSource, Loopback and Audio Hijack, has sold pay-once licenses for two decades and still does. Fader is a one-time App Store purchase. The open-source tools are free. The pattern isn't an accident — it reflects where the actual cost sits, which is in the one-off engineering, not in keeping a service alive.
The one-time apps, and what each costs in 2026
Here's the current lineup for controlling and routing Mac audio, with the pricing model and the job each one is built for. Prices are the publishers' listed US prices as of October 2026.
| App | Pricing model | Price | Main job |
|---|---|---|---|
| Fader | One-time | $19.99 | Per-app volume + output routing, keyboard-driven |
| SoundSource | One-time | $49 | Per-app volume, EQ, and routing from the menu bar |
| Audio Hijack | One-time | $69 | Recording audio from any app or device |
| Loopback | One-time | $99 | Building virtual audio devices and wiring apps together |
| Background Music | Free, open source | $0 | Basic per-app volume from a menu-bar list |
| eqMac | Free, open source | $0 | System and per-app EQ |
| BlackHole | Free, open source | $0 | Virtual audio cable for routing |
| Krisp | Subscription | from ~$8/mo (billed annually) | AI noise and echo removal on calls |
Only the last row is a subscription — and it's doing a different job. Krisp isn't a volume mixer; it strips background noise out of your microphone and speaker feeds using models that run with cloud support. That's the kind of work a monthly fee actually pays for.
Where a subscription is the right call
Being fair about this matters: a subscription isn't automatically a rip-off. It's the correct model when you're paying for something that keeps costing the maker money, or keeps getting better on their end while you sit still. Krisp's Core plan runs about $8 per user per month billed annually (around $16 month-to-month), and if you're on calls in noisy rooms every day, paying for noise removal that improves as their models improve can be worth every cent. You're renting an ongoing service, not a static tool.
The test is simple. Ask what you stop getting the day you cancel. With Krisp, you lose the live noise processing — fair, because that's the product. With a per-app volume app, there's nothing to lose on cancellation because there was never a server doing the work; the app just runs. Paying monthly for that would be renting something that costs its maker nothing to keep running. That's the arrangement to avoid.
The math over three years
One-time pricing looks more expensive at the checkout and far cheaper by the time you've owned it a while. A $19.99 app clears the cost of even a modest $8-a-month subscription in about ten weeks, then costs you nothing for as long as you keep using it. Over three years — a conservative lifespan for a utility you rely on daily — the gap is stark.
| What you pay | Up front | After 1 year | After 3 years |
|---|---|---|---|
| Fader (one-time $19.99) | $19.99 | $19.99 | $19.99 |
| A $8/mo subscription (billed annually) | $96 | $96 | $288 |
| A $16/mo subscription (monthly) | $16 | $192 | $576 |
The point isn't that subscriptions are always bad — it's that you should only be paying one when you're getting ongoing value for it. For moving faders around, you aren't, so you shouldn't.
What "one-time" really means on the App Store
One-time pricing has some fine print worth knowing, and it's genuinely good fine print. Fader's $19.99 is a single App Store purchase tied to your Apple ID. There's no renewal email, no account to manage, and Family Sharing is supported, so the household can use it on the same purchase. The 3-day free trial lets you confirm it fits before you pay anything — no card up front. It needs macOS 14.4 or later, because it uses the modern audio framework Apple shipped in that version.
The honest caveat on any one-time app, Fader included, is that "pay once" covers the current major version. Developers who sell perpetually sometimes charge a reduced upgrade fee years later for a big new version — Rogue Amoeba does this, with SoundSource 6 upgrades priced well below a new license, for example. That's still vastly cheaper than a perpetual monthly fee, and you're never forced to upgrade to keep what you already bought working.
How to choose without overthinking it
If your problem is volume and routing — one app quieter than another, music to AirPods while calls go to a headset — buy a one-time tool and be done. SoundSource is the deepest and most expensive of them; Fader is the cheapest paid option and the fastest to operate because it's keyboard-driven; the open-source apps cost nothing if you're willing to trade some polish and support. For the full breakdown of what the free options give up, see free vs paid per-app volume apps for Mac, and if you're weighing the subscription case specifically, Krisp vs Fader covers why those two tools aren't really competing for the same job.
Bottom line
For per-app volume, EQ and routing on a Mac, you don't need a subscription and shouldn't pay one — the whole category is one-time or free, because the work runs on your own machine. Save the monthly fees for tools that keep earning them, like cloud-based noise removal. If you want the controls under your fingers and the price paid once, Fader is $19.99, one-time, with a free trial to check the fit first.
Pay once, mix every app from your keyboard
Fader turns letter keys into per-app faders and routes any app to any output. $19.99 one-time, 3-day free trial, no account, no subscription. macOS 14.4+.
