Web Audio Patches

OWL
#1

We now have the ability to compile patches into Javascript and run them in the browser.

To try it out, check out this PD patch:
http://hoxtonowl.com/patch-library/patch/Arp_with_Delay_and_Envelope/
Click the Test tab and then Start to run the patch; use the knobs to change parameters.

Or for something with an audio input, try:
http://hoxtonowl.com/patch-library/patch/Ping_Pong_Delay/
Select an input then press Start to run the patch.

We’re still working on making sure that all patches in the library compile and run ok, so consider this a preview :slight_smile: and let us know what problems you find!

You can compile your own patches into Javascript too using the online compiler, check the Documentation for instructions.

Great feature!

#3

We’ve got more features on our todo-list than we can handle ourselves right now. If anyone’s up for donating some web development time just let us know!

#4

Am interested, what would you be looking for?

#5

Great! The wishlist includes:

  • waveform visualiser, showing the l/r outputs
  • Web MIDI: a new tab in the patch details that connects to your OWL to send patches and change settings (we’ve already got a proof-of-concept implementation)
  • patch recommendations and comments

Plus a whole lot of fixes and improvements. The issue tracker is here:

Thanks mars, will take a look

Hi,

I would like to compile a patch to JavaScript, but I just find the link to compile to sysex.

How can I compile to JS?

#8

We’ve streamlined the compilation stage so that both SysEx and JS are done with one action, using the Compile link. Details here:
https://hoxtonowl.com/forums/topic/web-midi/

#9

I’ve tried it, but when i click “Compile Patch” I just get the sysex version, no JS.
It is currently a private patch, can this be the reason?

#10

If you click the AUDIO tab, does it not play?

I removed the JS download link in the compact version of the web page as I didn’t think it was useful. It’s a responsive design: if you zoom out you will get both download links appearing in the left hand side box.

You can otherwise copy the sysex link and replace ‘format=sysx’ with ‘format=js’

Edit: I just realised there’s a problem with the deployed code, and the file was not copied over properly. Sorry - fixed now!

#11

Now it’s working perfectly, thank you!

#12

I love the js download feature. Do you mind, if i used js code of a patch of myself on my own website, if i linked back here as well?

#13

Sure, please do. A link back to the original patch page is probably most appropriate.

#14

Thank you! Will do! Should generate some extra interest in the Owl i hope.

#15

Is it up? Can we have a peek?

#16

Not yet. I’ll have to go through embedding the js code first. it’s tricky and i have to work on a composing job for a week before. I’ll let you guys know :slight_smile:
