I think that code is part of the Csound.js frontend.

I should also add my note of thanks to the Web IDE team. With the lockdown situation, this has been invaluable in my teaching,
I am using it actively with one group and encouraging another group to look at it too.

Hi Tarmo,

So glad to hear from you that the Web-IDE has been working out (and
for Victor too!)!  Victor's code from csound.js should be usable
copying it into your project, but I also went ahead and just put
together an example that uses a custom function I wrote based on
Victor's code:

https://github.com/kunstmusik/webaudio-csound-samples-example

You can test the site here:

https://kunstmusik.github.io/webaudio-csound-samples-example/

It uses samples from Freepats and a modified version of a project I
use for teaching samples. I added some heavy reverb and a simple
generative pattern.

One issue I did run into is that saving the files to a subdirectory in
the filesystem didn't seem to work. I think it's something we might
have fixed in the Web-IDE version of Csound that's in the process of
being backported to Webaudio Csound.  As long as you use writeToFS()
with a path in the root and load the samples from there in your Csound
code it should work.  Hopefully will be fixed in the next version of
Webaudio Csound.

Let me know if you have any further questions!

Steven
