 This component is written using the native  [Web Audio API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API), and does not use any dependencies other than vue3 in the production environment. Of course, this means: if your target browser does not support the features of the web audio api, then my Plugins will also not apply. You can go to  [Browser compatibility](https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API#audiocontext_2)  to see the `AudioContext` line to check whether it is compatible with the target browser
