Hi Tarmo,

I've used the enableAudioInput() before, but the message about Q is
odd; I'm not really sure what is happening there. For
requestControlChannel, you should be getting a value for value but
value2 would be undefined.  Is there source code you could point me to
to test?  (If it's a private project you can email me off list.) Could
you mention what OS and browser versions you are using?

Thanks!
Steven

I can test that, can you send me the file of the component?

Sorry, I have not had a chance to yet (end of term with lots of
grading at the moment!). I'll try to take a look at this later
tonight.

I ran things here and I had to use this code to get the control channel value:

    const getChannel = () => {
        csound.requestControlChannel("ratio",
          () => console.log("Ratio1: ", csound.getControlChannel("ratio")));
    };

I don't remember the design decision behind this but the callback does
not accept arguments in the current implementation. I was also able to
uncomment your code for audio input and got the OK option here once I
permitted microphone access on my browser for the page.

Just a note, I was working with Hlodver on a redesigned WebAudio
Csound that merges designs between what he has done in csound-wasm and
what we have in the current WebAudio Csound. I think some API methods
will change but largely for the better (e.g., most API methods will be
promise-based). That work stalled with the end of term here for me but
should resume next week. If all goes well we'll open it up for testing
while we iron out examples and documentation.

Hi Tarmo,

FYI: I added this issue to the issue tracker so that this information
gets added to the next WebAudio csound release:

https://github.com/csound/csound/issues/1417

All best!
Steven
