Overview

What Ardour does

Ardour is a digital audio workstation for Linux, macOS and Windows released under the GPL. It records and edits unlimited audio and MIDI tracks, has VCA masters, flexible bus routing, a video timeline for post-production, and Lua scripting for automating editing tasks and adding custom DSP. It integrates with JACK and with the native audio layer on each platform, and it is the codebase underneath the commercial Harrison Mixbus. The funding model is the fact that changes decisions. The source code is free and you may compile it yourself at no cost, but the tested installers the project builds sit behind payment: a monthly subscription from a low minimum, or a single payment of at least 45 US dollars that includes updates until the next major version. Nothing in the licence stops you distributing what you compile, so the payment buys convenience and funds development; it does not buy permission. In practice that means an organisation can standardise on Ardour across many machines with no per-seat licence cost by building it in house, which no commercial workstation allows at any price. It is used by Linux studios, post-production and dubbing work, broadcast and educational institutions that cannot buy per-seat licences, and people who object on principle to activation servers. The trade-off is content and polish. Almost no instruments or sample content ship with it, ARA is not supported, the MIDI editor is behind the commercial workstations, and support is community forums and a mailing list rather than a vendor with a response commitment.

What people use it for

Linux studios and broadcast facilities where the commercial workstations do not run at all
Institutions deploying a workstation across many machines without per-seat licences, by compiling and distributing their own build
Post-production and dubbing against a video reference, with Lua scripts automating repetitive edits
Archival work where a session must open in ten years with no activation server involved

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Ardour.

Almost no instruments or sample content ship with it, so a working music production setup needs third-party plugins that in practice cost more than a commercial workstation licence would have.
ARA is not supported, so Melodyne and similar pitch tools run as offline transfers, and the MIDI editor is behind Cubase, Live and Logic for anything past basic sequencing.
Support is community forums and a mailing list; there is no vendor with a response commitment, so a facility needing contractual support has to employ that expertise itself.
Plugin behaviour on Linux is fragmented across LV2, VST2 and VST3 with inconsistent GUI toolkit support, so a plugin working on one distribution is no evidence it will work on another.
The interface is dense and assumes you already understand signal routing, and the documentation lags the current release, so the first hours are slower than with a commercial workstation.

What people choose instead of Ardour

Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Ardourvs
REAPER
REAPER: Pick REAPER for a similarly cheap and similarly scriptable workstation with a much larger user base, better MIDI editing and an honour-system licence.
Ardourvs
Audacity
Audacity: Pick Audacity for straightforward recording and file editing where a full workstation with buses and automation is more than the job needs.
Ardourvs
Logic Pro
Logic Pro: Pick Logic Pro if you are on macOS, want a large bundled instrument library and a supported vendor, and the open source requirement is not a hard one.

Answered, with sources

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

Is Ardour free?

The source is free and GPL licensed. The prebuilt installers are paid, from a small monthly subscription or a single payment of at least 45 US dollars. You can compile it yourself at no cost and legally redistribute the result.

What does the single payment include?

A ready-to-run installer plus updates until the next major version. After that you pay again if you want the new major release as a prebuilt build.

Can an organisation deploy it on many machines without paying per seat?

Yes. The GPL permits compiling and distributing your own build internally, so there is no per-seat cost. What you give up is the tested official installer and the funding you would otherwise contribute.

Is Linux the primary platform?

Yes. The macOS and Windows builds are real and supported, but Linux is where the project is developed and tested first.
