Three different jobs, one price: free
Ardour, Audacity, and LMMS are all free and open source at their core, with no subscription required to use their full feature sets.
Ardour, Audacity, LMMS
Ardour is the only true professional DAW here
Ardour offers any-to-any signal routing, video timeline sync for scoring, sample-accurate sync to MIDI timecode and LTC, and control surface support that neither Audacity nor LMMS provide.
Ardour
Audacity is built for quick editing, not composition
Audacity is a waveform editor and recorder rather than a full DAW - it has no built-in synths, piano roll, or pattern sequencer, and instead focuses on recording, restoration, and format export.
Audacity
LMMS bundles a full instrument library
LMMS ships 16 built-in synthesizers plus the ZynAddSubFx synth, a piano roll, and a Beat/Bassline editor, giving producers a complete beat-making and arrangement toolkit without buying extra plugins.
LMMS
Only Ardour asks for money for convenience
Ardour's source is free, but ready-to-run binaries are funded via a $1 to $10 per month pay-what-you-want subscription or a free demo build that periodically interrupts playback; Audacity and LMMS carry no such gate.

No. Audacity is a multitrack audio editor and recorder focused on recording, cleanup, and format conversion; it does not include the built-in synthesizers, piano roll, or pattern sequencer that make Ardour and LMMS full digital audio workstations.
No, Ardour's full source code is always free to download and compile. Ready-to-run binaries are funded through an optional pay-what-you-want subscription starting at $1 per month, or you can use a free demo binary that periodically interrupts playback.
LMMS, since it ships 16 built-in synthesizers, the bundled ZynAddSubFx synth, and a dedicated Beat/Bassline editor built specifically for pattern-based production, none of which Ardour or Audacity offer out of the box.
Ardour, which includes video timeline integration for scoring plus sample-accurate sync to MIDI timecode and LTC - capabilities not documented for Audacity or LMMS.
Yes. All three - Ardour, Audacity, and LMMS - run natively on Linux, macOS, and Windows, even though all three originated as Linux-focused, open-source projects.
Yes. Ardour supports AudioUnit, LV2, VST2, VST3, and LADSPA; Audacity supports VST3, LV2, and Nyquist; and LMMS supports VST plugins on relevant platforms, so each can be extended beyond its stock toolset.
