CheapTrick_JS error #3

Closed baba5246 closed 3 years ago

baba5246 commented 3 years ago

Thank you for developing the javascript version of World!! I built WorldJS.js as described in the README, and tried it on a simple web server, but the following error came up. It seems to be an error related to the detached ArrayBuffer in WorldJS.wasm. I have confirmed that the Dio_JS function, written before CheapTrick_JS, can run and output an f0 value. How can I resolve this?

Uncaught TypeError: Cannot perform %TypedArray%.prototype.set on a detached ArrayBuffer

Sorry for taking so long to reply. Try to use the latest branch of World.JS, I am currently not got such an error. The latest build added more debug information.

Well, I know. You read the static/js/lib/vaiueo2d.wav file in the wrong place. World.JS Currently, it does not support reading files directly from the hard disk. The current method is to provide *.data file to import the wav file.

The File System is based on Emscripten, not basic JavaScript
