Hi all !

I'm trying to send an audio stream from PD to VVVV (in order to create a nice visualiser according to the sound), I got no problem to receive or send simple data (like floats) between vvvv and pd, but I don't know how to send an audio stream with [sendOSC] (I didn't find any clue in the help file)
Is it possible to do it ?

Edit: Ok, finally I manage to do it without OSCs (by capturing sound directly from my soundCard in vvvv)

But, I would like to send 3 differents audio stream from pure data to vvvv (from 3 different abstractions, I would like to create a visualiser for each one, working simultaneously)that's why I'm still looking for a way to send them to vvvv (with OSCs?).

so if anyone has an idea, please tell me ^^

OSC is only for control data not signal data. It is designed to be an awesome replacement for MIDI. Without knowing more (your OS, your background, what exactly you want to do) I can only give general suggestions.

One option might be to do the audio analysis in PD and then just send control numbers to vvvv via OSC.

If you need to deal directly with the audio in vvvv you will most likely need to use something like JACK which should allow you to put sound where ever you need it.

Of course if you can get the sound into vvvv directly you might not need PD at all.

Hi, thanks for your help ^^

in fact I'm running on XP, and I'm building a patch in PD with 3 general sound modules (for example : one for drums/rythm, one for bass and one for treble), and I would like to generate 3 graphs in vvvv, one for the drums'module, one for the bass'module and one for the treble'module.
that's why I need to send each module's output separately (and so I can't just capture sound from my sound card).

My graphs in vvvv are generated simply, just classic audio curves (I need vvvv because I put some graphic shaders on them) that's why your suggestion about sending control numbers could match.

But I never did that before, how can I get control numbers from an audio output in pd ?

also, I took a look at JACKdmp, It seems very interesting, I'll try it tomorrow, and see if it can match with my work.

I would recomend giving method 1 (analysis in PD) a shot.
I originally thought you were analyzing outside sound.

Since the sounds are coming from PD getting good control data shouldn't be hard.

Once you get data you like OSCing it out of PD is pretty easy. (I'm assuming its similarly easy on the vvvv side, I not familiar with vvvv)

>how can I get control numbers from an audio output in pd ?<

[env~] for the amplitude,

[fiddle~] for the pitch

Ok Great !

Thanks a lot guys

[bonk~] looks for percussive attacks in a sound source.

thanks for that

Currently I'm trying different ways,
I'm using fiddle~ and sending controls values to vvvv (but I got some difficulty to generate curves with it in vvvv) (if it works, I will try adding values from bonk~ and env~ )
also I try to send audio stream with external applications, I tried JACK but it don't wanna launch correctly on XP, also somebody told me about VirtualAudioCable, I tried it, and it seems to work (I think it's quite similar to JACK).
It creates some virtual cables available as audio input and output in Pd, but is it possible to have several output at the same time in pd ?
for exemple, abstraction "a" send output signal using virtualcable 1 and abstraction "b" send output signal using virtualcable 2 ?
maybe this is stupid but I ask that because I saw that there is the option "use multiple device" in MMIO, but when I try to set 2 virtualcable as output it send the error :
"separate audio device choice not supported\; using sequential devices."
