[PD] vu-meter question

[Derek Holzer]

You were close, you just didn't include a space in an object name:

[number box]
|
[osc~]
|
[env~]
|
[- 100]
|
[vu]

But keep in mind that quickly refreshing graphics in the patch will 
dramatically affect overall audio performance. If you just need to know 
if you are close to peaking, this could work too:

["some sound source~"]
|
[env~]
|
[> 0.90]
|
["graphical bang"]

Or this:

["some sound source~"]
|
[env~]
|
["number box with very slow refresh rate set in properties"]

good luck!
