Help running example about essentia.js HOT 4 CLOSED

Hi Will,
Sorry I may not be of a lot of help right now (I'm sitting in my plane back from WAC waiting to depart...)
About the complain that typedFloat32Array2Vec doesn't exist, did you include the following function in your code?

typedFloat32Array2Vec = function(typedArray) { var vec = new Module.VectorFloat(); for (var i=0; i<typedArray.length; i++) { if (typeof typedArray[i] === 'undefined') { vec.push_back(0); } else { vec.push_back(typedArray[i]); } } return vec; }

Hi, I think I've got past that problem, the html in the readme defines a function called typedFloat32Array2Vec but tries to use it as typedFloat32ArrayVec (note the missing 2). So if I create an audio buffer and fix the typo, I get a bit further, but now I get:

The missing function it seems from the C++ is a string called windowType, do you know what values this is expecting? I tried 'hann' and a few others in https://github.com/MTG/essentia/blob/96531284a35ef6142c6e6ed80cad8b82a9751e2e/src/algorithms/standard/windowing.cpp#L49 but it seems I now get this message Compiled code throwing an exception, 5959664,18536,11

Hi Will, I'll look into it.
Thanks.

Hey @willm, thanks for the feedback. The above-exception was due to the outdated wasm builds. Made a couple of changes as well. Now it should work as expected. Let me know if not.

The existing essentiamin-0.0.1.wasm builds in the repo is compiled with --emrun linker flags to capture stdout and stderr streams (which is useful for debugging). For dev purposes, you can use emrun tool from emscripten to launch the html page on the browser.

Or if you use the python http server for launching, add the mime type for wasm. Check this mdn/webassembly-examples#5 out. Try this example to add your mime type https://gist.github.com/HaiyangXu/ec88cbdce3cdbac7b8d5.
