SoundSource alternatives

All apps re-checked October 1, 2026; effects re-checked October 2 · Page updated October 2, 2026

The best SoundSource alternative depends on why you're leaving it. EQBase is the fullest replacement, with a free tier and a deeper equalizer; Sound Control ($30 once) is the closest like-for-like for per-app volume; FineTune and Background Music are free; and Loopback goes beyond SoundSource's routing.

Disclosure first: we make EQBase, which is one of the seven apps below. It is listed first because this page ranks by how many of the four reasons below each app covers, and on that count it leads; for many people reading this page it will still not be the right pick. If we've got a detail wrong about any of the others, tell us and we'll correct it.

SoundSource is very good. People go looking for alternatives for four specific reasons, and which one applies to you decides the answer:

• Price. It's $49, one-time, with no free tier; the trial overlays noise on your audio after 20 minutes.
• SoundSource 6 requires macOS 15. If your Mac is on Sonoma or older, the current version won't run at all.
• You only wanted one feature (usually per-app volume) and $49 for a volume slider feels steep.
• You wanted a deeper equalizer. SoundSource's is a 10-band graphic EQ; some people arrive expecting a parametric one.

The short answer

For per-app volume control, the SoundSource alternatives worth evaluating are Sound Control ($30 once, macOS 14.6+), the closest like-for-like; FineTune (free and open source, macOS 15+); EQBase (per-app volume in Pro, with a free tier, macOS 14.4+); eqMac (per-app volume in its paid tier, macOS 10.13+); and Background Music (free, volume only, still alpha). Sound Control, FineTune and EQBase can also send an app to a different output, as SoundSource does.

• Want a deeper equalizer, or a free way in? EQBase, ours: free tier with no time limit, 24 parametric bands in Pro, room measurement that fits the correction for you, and it routes per app too.
• Want the same thing for less, with no setup? Sound Control at $30, with per-app routing from a per-app control.
• Want it free? EQBase's free tier or eqMac for EQ, FineTune for per-app volume and routing on macOS 15, Background Music for per-app volume alone on older Macs.
• On an older Mac? EQBase (macOS 14.4+), Sound Control (14.6+), eqMac or Background Music (10.13+). All of them go lower than SoundSource 6's macOS 15.
• Need routing more complex than SoundSource offers? EQBase's patchbay, or Loopback from the same developer.

1. EQBase: the fullest alternative

Free tier, no time limit · Pro $4.99/mo, $39.99/yr or $79.99 once · macOS 14.4+

This is ours, so treat the rest of this section accordingly, and check it against the table below.

It covers the four things people leave SoundSource for. Price: the free tier never expires and never overlays noise on your audio, where SoundSource has no free tier at all. macOS: it runs on macOS 14.4, so it works on the Sonoma Macs that SoundSource 6 locks out entirely. Depth: where SoundSource gives you a 10-band graphic EQ, EQBase gives you 24 parametric bands with your own frequency, gain, Q and filter type, plus linear-phase and dynamic filters, separate left/right curves, 8,600+ AutoEQ headphone corrections, convolution for measured room correction, and crossfeed. It adds zero samples of latency to the direct signal, and when everything is flat it's bit-perfect and verifies that continuously against the live signal. Setup: nothing to install beyond the app and no administrator password, where SoundSource puts an audio component on your Mac and asks for one.

It also measures rather than guesses. Play a sweep, capture it with a microphone, average several listening positions, and EQBase fits the parametric correction for you, into a layer that sits underneath your own EQ instead of overwriting it. Around that: equal-loudness compensation on the ISO 226 contours so quiet listening keeps its tone, speaker crosstalk cancellation with the delay taken from your actual speaker geometry, an analysis suite (spectrogram, goniometer with correlation, VU needles and a floating always-on-top meter), and one-click recording of the processed output to MP3, AAC, ALAC, FLAC, WAV or AIFF. SoundSource does none of those, and Rogue Amoeba sell recording separately as Audio Hijack.

Pro also carries a routing patchbay that does what people mostly come to SoundSource for, sending chosen apps to chosen output devices, and goes further: up to four virtual devices, each feeding up to eight physical outputs, on buses up to 64 channels with a per-channel matrix, each published as an input Zoom or OBS can record, and each output carrying its own EQ so two rooms can run two different curves at once. For the common case there is no graph to build: each App Mixer row has a Play on menu that sends that app to another output, or to up to eight at once, with nothing extra to install. Anything more elaborate is built as a graph, which asks more of you up front.

Best for: anyone who wants a deeper equalizer, a free way in, or a Mac SoundSource won't run on.
Trade-off: macOS 14.4+ only, per-app volume and routing are Pro rather than free, and its one-time price is the second highest here, after Loopback. Full detail: EQBase vs SoundSource.

2. Sound Control: the closest like-for-like replacement

$30 once · macOS 14.6+ · free trial

If you want what SoundSource does and you want to pay less for it, Sound Control by Static Z Software is the honest recommendation, and it's the one most "alternatives" lists bury. It covers the same three jobs: per-app volume and mute, per-app equalization, and rerouting an app's audio to any output device. It adds a 10- or 31-band graphic EQ, Apple's AUNBandEQ for parametric headphone and speaker calibration, thousands of AutoEQ headphone profiles, Audio Unit effect plugins, hotkeys, and full MIDI control if you want a physical knob driving app volume.

Version 3.4.0 shipped in September 2026 and needs macOS 14.6 or later: Static Z's site still says 11.4, but the current download declares 14.6. It is also sold as a Mac App Store subscription ($1.99 a month or $14.99 a year, macOS 15.6+), licensed separately from the direct version.

Best for: people who specifically want SoundSource's feature set, for less, or on macOS 11–14.
Trade-off: it's a smaller operation than Rogue Amoeba, without the same twenty-year support history behind it.

3. FineTune: free, and it routes too

Free · GPLv3 · macOS 15+

FineTune is the free option that covers the most of SoundSource's own job: per-app volume with boost and mute, a 10-band EQ per app, and sending any app to one or more other outputs. It also keeps the volume keys working on HDMI and USB outputs.

Best for: SoundSource's core features at no cost, on macOS 15 or later.
Trade-off: the same macOS 15 floor as SoundSource, so it is no help on a Mac that can't take macOS 15.

4. eqMac: free and open source

Free · Pro from $3/mo, $30/yr or $40 once · macOS 10.13+

eqMac is free, published under Apache 2.0, and runs back to macOS 10.13, further back than anything else here. The free tier is genuinely usable, and Pro adds a parametric EQ, spectrum analyzer, per-app volume, Audio Unit hosting and 4,600+ headphone corrections at prices below every paid option on this page.

What it does not do is per-app output routing. If you came to SoundSource for "music to the DAC, everything else to the speakers", eqMac won't replace it. If you came for EQ and per-app volume, it will, for nothing.

Best for: a zero-cost start, older Macs, or anyone who wants to read the source of a user-space audio driver.
Trade-off: no per-app routing. We have a longer EQBase vs eqMac comparison, including where eqMac beats us.

5. Background Music: free, and only does one thing

Free · GPLv2 · macOS 10.13+

If the only feature you wanted from SoundSource was per-app volume, Background Music does exactly that and nothing else, for free. It also auto-pauses your music player when another app starts making noise, and lets QuickTime record system audio. Version 0.5.0 shipped in June 2026.

Be clear-eyed about it: the project still describes itself as alpha, it's stereo-only, it has a long list of open issues, and it's volunteer-maintained rather than a product with a support desk. There's no equalizer and no routing. But 19,000-plus people have starred it for a reason: for the narrow job it does, it works and it costs nothing.

Best for: per-app volume, zero budget, and a tolerance for rough edges.
Trade-off: alpha software, no EQ, no routing, no support.

6. Loopback: when SoundSource isn't enough routing

$99 once · macOS 14.5+ · trial with limitations

Some people land on "SoundSource alternatives" because SoundSource can't do what they need, not because it costs too much. If you're building a podcast rig, feeding app audio into a streaming tool, or combining several apps and microphones into one device that other software can see, Loopback, from the same developer, is the step up. It creates virtual audio devices from any combination of apps and hardware, with up to 64 channels.

It is not a cheaper SoundSource. There's no equalizer and it isn't a per-app volume panel; it's a patchbay. At $99 it's also the most expensive option here.

Best for: recording, streaming and multi-source routing rigs.
Trade-off: wrong tool entirely if you just wanted app volume sliders.

7. Boom 3D: if you wanted it louder and bigger

About $17 once from Global Delight (list $49.99, usually discounted) · macOS 11+ · 15-day trial

Boom 3D isn't really a SoundSource competitor, but it catches a lot of the same searches, because some people wanting "better sound" want an enhancer rather than a control panel. It does 3D surround, volume boosting, a 31-band graphic EQ, per-app volume, internet radio and a media player, it's on the Mac App Store as a free download that unlocks through in-app purchases, and one licence covers Windows too.

Best for: making music sound bigger and louder, cheaply, without a driver install prompt from an App Store purchase.
Trade-off: it's colouring, not accuracy, and there's no per-app routing. See EQBase vs Boom 3D.

Compared

One-time prices shown where both options exist. A "–" under free option means trial-only. EQBase's free tier does not include its per-app volume or routing, which are Pro. Prices and system requirements as published on October 1, 2026.

Which Mac audio apps can apply effects like compression or limiting across system audio or to individual apps?

Across everything the Mac plays, EQBase has compression and limiting built in, and SoundSource, Sound Control, eqMac (Pro) and EQBase (Pro) all host Audio Unit plugins for any compressor or limiter you like. On a single app, SoundSource and Sound Control are the two that can put effects, plugins included, on that app alone; EQBase, eqMac and FineTune stop at per-app volume and, in EQBase and FineTune, a 10-band EQ per app. Same disclosure as above: EQBase is ours.

EQBase's Night Mode, on the Devices pane, is a deliberately gentle compressor with one Strength control: it eases loud passages down and lifts quiet ones so dialogue stays clear at low volume, and it adds no latency. The safety limiter is always last in the chain and free; the optional True-peak limiter in Settings, General holds inter-sample peaks below −1 dBTP for exactly 2 ms of latency. SoundSource's built-in Magic Boost and Volume Overdrive are loudness effects; for a real compressor or limiter there, and in Sound Control and eqMac, you load an Audio Unit. Audio Hijack (version 4.6.0, macOS 14.4 or later), also from Rogue Amoeba, ships a Simple Compressor, Magic Boost and plugin hosting, but applies them inside the sessions you build in Audio Hijack, which is a recording and streaming tool first.

Which to pick: a compressor on one app only, such as a quiet podcast app but not your music, means SoundSource or Sound Control. Compression and limiting on everything, with no plugins to find and no added latency, is what EQBase's Night Mode and limiter do. Prices and requirements as in the table above; effects checked on each developer's site on October 2, 2026.

When SoundSource is still the right answer

Worth saying plainly on a page like this. If you're on macOS 15 or later, $49 is inside your budget, and you want per-app routing plus per-app Audio Unit effects plus output groups plus AirPlay in one polished panel with twenty years of support history behind it, buy SoundSource. Nothing on this list does all of that. Sound Control gets closest and costs less, but it doesn't have Output Groups or the same track record.

Also note that Rogue Amoeba keep older releases available. If your Mac can't run macOS 15, an earlier SoundSource version may still be an option; ask them before assuming you need to switch apps at all.

Things that look like alternatives but aren't

BlackHole and similar virtual audio drivers come up constantly in these discussions. They're free and excellent, but they're plumbing, not applications: they give you a virtual device to route audio through, with no interface for per-app volume, no equalizer and no per-app control. If you're comfortable building a Multi-Output Device in Audio MIDI Setup they can solve narrow routing problems for free. They will not replace SoundSource's front end.

Audio Hijack, also from Rogue Amoeba, is likewise a different job: recording and processing audio to a file, rather than live system control.

How to choose

Answer one question: is your problem where the audio goes, or how it sounds?

Where it goes (different apps to different devices, or several devices at once) means Sound Control at $30, FineTune for free on macOS 15, or Loopback if the rig is complicated. How it sounds (headphones that measure wrong, a room that booms, a recording that's too bright) means an equalizer, and eqMac is the free way to test that theory before anyone charges you anything.

If you're still not sure a system-wide tool is what you need, start with does macOS have a built-in equalizer? or per-app volume control on a Mac. Both cover the free workarounds first. EQBase's own tiers are on the pricing page.
