FineTune is a free, open-source Mac utility that gives each running application its own independent volume level, equalizer, and audio output destination — something macOS has never offered natively.
What is FineTune?
FineTune is a per-application audio control layer that sits between your apps and macOS's audio stack. Instead of the single system-wide volume slider Apple gives you, FineTune surfaces a separate fader, EQ, and routing selector for every app that's currently playing sound. Think of it as a mini mixing desk that lives in your menu bar.
The project is community-built and hosted on GitHub, which means it's free to download, actively maintained through pull requests, and fully inspectable if you're the sort of person who reads source before installing audio utilities.
What does FineTune do best?
FineTune's strongest suit is its per-app routing: you can send Spotify to your studio monitors over USB while Zoom calls come through your AirPods — simultaneously, without switching the system default. That alone makes it indispensable in dual-output setups.
The per-application equalizer is a genuine surprise at this price. I've used it to tame the harshness of video-conferencing codecs — a quick dip in the upper-mids on Zoom makes long calls noticeably less fatiguing — while leaving music apps completely untouched. It's the kind of granular control that previously required a paid product like Rogue Amoeba's Loopback or SoundSource.
- Independent volume per app — a dozen apps, a dozen faders
- Per-app parametric EQ — shape tone without affecting anything else
- Per-app output routing — different hardware destinations per app
- Menu-bar access — no Dock icon, no distraction
- Zero subscription, zero nag screen
Is FineTune free?
Yes — FineTune is completely free. There is no Pro tier, no trial limit, and no account required. You install it, launch it, and it works. The trade-off is that support is community-driven rather than commercial; bug reports go to the GitHub issue tracker, not a help desk.
If you need the deep professional feature set of Rogue Amoeba SoundSource or the loopback routing graph of BlackHole combined with a paid front-end, those products are worth the money. But for the majority of users who simply want per-app volume and basic EQ, FineTune covers the ground at no cost.
Who should use FineTune?
FineTune is built for anyone whose Mac doubles as a workstation and a media machine simultaneously. Remote workers who need Slack notifications quieter than background music without touching the system slider will feel immediate relief. Podcasters and streamers who monitor multiple audio sources through different outputs will find the routing table genuinely transformative.
It's equally useful for people with hearing asymmetry who want a different EQ curve applied to their conferencing app versus their DAW output, or for students sharing a space who want to cap notification sounds at a whisper while keeping lecture audio full volume.
Power users already running SoundSource may find FineTune redundant — SoundSource's polish and stability edge ahead in demanding workflows. But if you've been living with macOS's one-size-fits-all audio model and haven't wanted to pay for a commercial tool, FineTune is the obvious first stop.
How does FineTune compare to SoundSource?
SoundSource by Rogue Amoeba is the gold standard for per-app Mac audio control: rock-solid CoreAudio integration, system-extension reliability, excellent documentation, and paid customer support. FineTune doesn't match it on stability guarantees or breadth of advanced routing options.
Where FineTune wins is the cost-to-feature ratio for everyday use cases. If you need volume-per-app and basic EQ and don't need Rogue Amoeba's advanced channel strips, AU plugin hosting, or commercial support, FineTune delivers exactly what you need from a GitHub download. Think of SoundSource as the professional studio desk and FineTune as the smart field mixer you keep in your bag.
What are the best FineTune alternatives?
The closest paid alternative is SoundSource (Rogue Amoeba, ~$39 one-time), which offers a superset of FineTune's features with commercial-grade stability. Loopback, also from Rogue Amoeba, focuses more on virtual cable routing and multi-source mixing for podcasters. For pure audio routing without an EQ layer, BlackHole (free, open-source) is the community favourite — though it requires more manual setup. eqMac offers system-wide EQ for free with per-app control in its paid tier, making it a natural comparison point for the EQ side of FineTune's feature set.
