A port of a port to TypeScript. Pitchshift and Timestretch in JS/TS. This library is LGPL2.1 due to SoundTouch. A more tested port of this library, with more utilities, is available in soundtouch-js. This TS port exists because I wanted the types, and didn't know soundtouch-js existed until recently.
However, as long as you allow a user, at runtime, to swap out this library, it should fall under section 6b of https://www.gnu.org/licenses/old-licenses/lgpl-2.1.en.html. But JS/TS and LGPL are legally ambiguous, so use at your own risk.
