passing audio thru javascript


December 2, 2008 | 2:43 pm

Is there a way to pass audio through a javascript?

i tried setting up a

function audio (val) {
outlet(0,val);
}

but that doesn’t seem to work.

any help is VERY appreciated, thank you,

You could do that (iPhone coding…):

function signal()
{
outlet(0, arrayfromargs(messagename, arguments));
}

Although this won’t do much… Except routing, but in a static way
when you start the DSP chain.

Thank you for answering Emmanuel,

how COULD i trigger the function called signal() from outside the js object?
i cant seem to run audio thru a message like [signal $1] and then into the js. the message object just doesn’t accept an audio cable on it’s inlet.
actually just routing thru to a dedicated outlet is exactly what i need. would you happen to have a more complete example, which includes the external setting?

i have posted an example patch and js file below.

Thanx very much for looking into this!

this may seem like a silly question but… does this meean that there is a message ‘signal’ prepended to every value output by all signal objects? I’m thinkning this might give me a bit of a deeper understanding of how things work in Max as there doesn’t seem to be too much in the docs that would give you this kind of info…

where might I read up on useful info about the underlying functioning of max that isn’t covered in the help?

Sorry, I know its a bit vague.

remover, "signal" here is the name of the javascript function EJ had posted further up in this thread. i don’t know too much about the underlying programming of max nor msp, many things can be guessed though by opening patches as text.

anyone else on routing audio through javascript?

i think my example patch is almost there…

Thank you very much,

Thank you for the insight, Emmanuel.

Well, my idea is to use a bit of javascript inside a poly~ object in order to send signal from it’s individual instances to individual receive objects.

i can’t see any other way, than using javascript to create individual send objects for individual instances, the only otehr option i could see, but are not capable of, is using a script to only create the individiualized send object and be able to connect this back to an object already present in the root patch of the poly~. but i couldn’t find out, if or how that works.

Please let me know, if that would be an option to go, hopefully with a hint how to establish that.

Thank you again,

Emmanuel, i lacked half of my answer.

In fact i needed to set a routing only once. There’ll be no need for dynamic changes after the patch has loaded. Would that help the issue?

to create individual send~s for each instance of a poly, use loadbang
to thispoly~:

Oh, i already send signal into the [poly~] using [in~]. what i’m trying to achieve, is to sending signal out from each poly instance to a different location afterwards. i can’t get to do this using [out~], as then all [poly~] signal is using the same outputs.

M: Thank you! …unfortunately i am on max 4.63.

Also i used the loadbang -> thispoly~ combination to pass on the instance number to my script before. my problem is, that i neither can’t seem to route audio through my script (which needs to establish that only during loading, but not later) as well as i can’t seem to find a way to connect a dynamically created and individually named send~ object to connect back to an audio source within the patch.

it’s a bummer, i know.

yes, Emmanuel, that’s almost what i did now, instead i hardwired a gate to several send~ objects, controlled by thispoly~. the beauty is gone, though, as the otehr approach would have allowed to change the number of poly~ instances at any time.

i’ll reserach further.

Thank you all for your replies.
