FAQ

Questions & answers

Does each preset turn every note into a single frequency?

No. The plugin adjusts the overall tuning while preserving the intervals between musical notes. The presets reference specific notes; they are not single-frequency filters.

Does it work with every DAW?

Compatible with 64-bit Windows DAWs supporting the VST3 plugin format.

Can I work offline?

Yes. An Internet connection is required for the first activation, then the plugin has been tested to work without a connection on the activated PC.

Can I process YouTube and all Windows audio?

That is the central goal of the separately planned Standalone edition. The current VST3 plugin needs a compatible audio host.

Is Spiritual Tuner open source?

It is built from a modified GPL-licensed open-source foundation with extensive product-specific development. The GPL and applicable third-party rights remain in force. Visit the Open source page for details.
