MoonMel's project source is licensed under [MIT](LICENSE). No third-party DSP implementation is linked into the runtime; the standard MoonBit core library is provided by the toolchain. Numerical formulas are implemented in MoonBit and the project's reference scripts call external libraries to compare results. This notice does not relicense those libraries.
