Hi everyone,

I would like to cotrol the output level of my patch.
I've try to use the VU (in the "put" menu) but I don't understand how it works....
Is there a way to get my audio in this VU?

Thanks

go to help->browser

answer is you need a *~, something to give it a value and a dac~

The [vu] only accepts messages, so you need use [env~] to get the rms dB level, then rescale it. [env~] uses 100 dB to represent full scale, but [vu] uses 0 dB.

Accurate peak metering is pretty bitchy, and I'm not aware of an external that does it well, but you can at least use [edge~] to detect if it's clipping.

[expr~ abs($v1)>1]

[edge~]

[bng] <-- will bang when out of -1 to 1 range

oh i thought he just wanted a volume control
interestingly there isn't even a help patch for edge~

I made one a while back.

Ok thanks I've made one but I think I didn't rescale the output of the env~ correctly...

Here's my patch. Is it OK?

so what about my quick idea?
but as mmb stated that's not accurate because of env~

I've done this before without too much headache, and I don't see any problem with it.

(If you have more than output) connect all of your outputs to a [+~] object, connect this to a [env~] object, then to a [- 100] object, then to a number atom, finally send the output of the number atom to your VU meter.

I just took a look at that thing, your code should work (and you don't need a [+~] obj). To make it look pretty, switch the [- 100] and number objects, then do a send from the number atom to the VU meter so that you don't see a patch cord going into the meter.
