QUESTION
I am using Angular for development of a video conferencing web application. I am trying to call some wasm functions in my AudioWorkletProcessor
class. However, I am quite stuck on how to pass the wasm module into the AudioWorkletProcessor
and then call those functions. I was able to instantiate the wasm module from the js file generated from emcc (using command: emcc test.cpp -s WASM=1 -s MODULARIZE=1
) and then tried passing this module through the options.processorOptions
parameter when we construct the AudioWorkletNode
; however, it seems like Function objects cannot be passed as it gives a DataCloneError
. Is there a better way of instantiating the wasm module and passing it into the worklet processor so that I can use its functions?
Code of audio.service.ts:
...ANSWER
Answered 2021-Jan-11 at 21:57Passing an instantiated WASM module to a worker (or an AudioWorklet) isn't possible. It only works when the WASM module is compiled but not yet instantiated. There is an example on MDN which shows how to do that with a regular worker but it works the same way when using the processorOptions
of an AudioWorkletProcessor
.
The idea is to use compileStreaming()
on the main thread and instantiate()
in the worker.
On the other hand it's also possible to import everything directly into an AudioWorklet as shown in this example. However, I would not recommend doing that since compiling the code on the audio thread may result in an audible glitch.

QUESTION
I am currently using Angular to build a video conferencing application. In one of my services, I try to incorporate the web audio api. The problem is when I try to add a script to the audio worklet using the addModule(AudioWorkletProcessorFileName.js)
function, it throws a SyntaxError: Unexpected Identifier
. I have found that it only happens when I try to import another file into AudioWorkletProcessorFileName.js
. When I remove the import
statement, everything works fine. There is more complex code that I want to import, but I wanted to start off with a more simple version of test.js
(the file I want to import). I am not sure why this is the case. Am I missing some configuration settings in Angular or something else?
In audio.service.ts:

Answered 2021-Jan-08 at 23:09As mentioned in the comments above this was a bug in standardized-audio-context which did not correctly resolve relative paths inside of an AudioWorklet. It should be fixed in version 25.1.7 and above.
