Hi all,

I want to be able to "ask" the dac or a patch if it is producing audio.

I was looking at doing something like this;

[some_signal_producing_object]
|
[evv~ 500]
|
[> 0]

This produces 1 when audio is being produces and 0 when it's not, however the problem is I don't know how to bang this setup to acquire the playing state.

I'd like to ask it, "are you playing audio?" and then get a single response, yes / no.

Does anyone have a suggestion as to how I might proceed with this?

Just print the message [;pd dsp( - It will print your DSP state.

[;pd dsp(
|
[print]

Hi, what about this?

Take care,
Gilberto

What about an array and a [tabwrite~] connected to the [dac~]? Then you can SEE if the thing is alive. Just a silly idea, instead of strictly answering your question.

Hi all,

Thanks for your help guys. I will try out your suggestions this evening when I get home from work.

All the best,
David.

If you want to be able to check the audio at will you can use the method you described and store the result in a named [value] or [v] object. Then you can check the current state anywhere in your patch by banging a [value] with the proper name.

If you only need to check the audio at a single point in the patch then you can use the cold (right) inlet of a [float] or [f] object to store the state and bang the hot (left) inlet to retrieve it.

Thanks for all your help everyone.

This is my final solution;'

- subpatch

Audio In with [inlet] and not [inlet~]?

Thanks Gilberto, I updated the subpatch to take an audio signal.
