No cost threshold: the tool is free, so the only cost is the time spent learning the interface.
About
In practice. What you can do with Audacity.
Audacity is a desktop multi-track audio recorder and non-destructive editor with built-in effects (noise reduction, EQ, reverb, echo) and spectrogram analysis. It imports, exports and converts common formats like MP3, WAV, FLAC and AIFF, and supports VST3 and Nyquist plugins, with LV2 on Linux and Audio Units on macOS.
It is entirely free and open source, with no paid tier or feature gating. It fits a solo podcaster or content creator recording and cleaning up voice audio on a desktop, though it lacks MIDI editing or virtual instruments, and has no official mobile app.
Practical uses

When it makes sense. Keep Audacity, or challenge it?
Keep if

Our verdict. What to know about Audacity.
Why this verdict
Great
Added value
Free and open source with multi-track editing, built-in effects and wide format support, no equivalent free desktop editor this complete.
Simplicity
Getting a usable edit takes some learning of the interface and effects; some formats need a separate FFmpeg install first.
Fit for purpose
Records, edits and exports audio in common formats as promised, with plugin support extending it further.
Performance
Strong for recording and editing, but explicitly not a full DAW: no MIDI editing or virtual instruments.
Reversibility
Exports to open, standard formats (WAV, FLAC, MP3) and is open source itself, reducing lock-in.
