FAQ

FAQ

Is it really free? Yes, and staying that way. No paid tier, no subscription, nothing behind anything. The licence is all-rights-reserved (see LICENSE) - the source is open to read and build, not to redistribute.

Do I need an account? No, and there is nowhere to make one. No server exists.

Does it send anything anywhere? Only when you press the update button, which asks GitHub whether there is a newer release. Nothing else, ever. No telemetry.

Why is it not signed? Signing means buying a certificate issued against a verified legal identity

• around $99/year from Apple, $200-500/year from a Windows CA. That has not been bought yet. You can always build from source instead.

Will my progress survive an update? Yes. It lives in a settings file no installer touches.

Which is better, VST3 or AU? No difference here. Use whichever your host prefers.

Can I use the Learner plugins as normal effects on a real mix? Yes. They are real DSP with host-automatable parameters that save with the session. The teaching is additive, not a mode.

Why per-exercise levels instead of one? Because being good at panning says nothing about hearing 400 Hz. One number would average away the only useful information.

Why no leaderboard? There is no server, so a comparison against other people would either be fabricated or require a completely different product with accounts and a privacy position. Comparison against your own past is honest and, for a skill, more useful.

Can I get it in my language? Twelve are built in: English, Russian, German, French, Spanish, Portuguese, Italian, Polish, Ukrainian, Simplified Chinese, Japanese, Korean. Nine of them have only been machine-checked - corrections are a very welcome pull request, one JSON file in shared/i18n/strings/.

Parameter tooltips, lesson text and the training modules are still English-only.

Can I add an exercise? Yes, and the process is short: implement the Game interface, append it to GameManager (never insert - per-exercise stats are keyed by index), add it to CMakeLists.txt and to categoryForGame(). CLAUDE.md has the detail.

Where do I ask something not answered here? Discussions → Q&A. Something broken goes in Issues.
