My patch has a standard VU meter and I'm sending VU meter Float values to an IOS app.

Everything works perfectly except that my app receives 4-5 messages per millisecond... which bogs down resources.

How do I force Pd to send one messages at a fixed time interval like 10ms?

Do I use pack for that?

Thanks!

Try [speedlim], maybe.

oops I should have specified I can only use Pd Vanilla objects for IOS apps

I have lots to learn about Pd...is it possible to use a [metro] object to control the timing of messages?

I stuck a metro object in there but it didn't work - I didn't get any messages through at all - am I missing something or [metro] can't be used this way?

now I've got this:

[r~ VU Input]
|
[env~]
|
[-100]
|
[VU METER]
\
[loadbang] \
\ \
[metro 10]
|
[send VU]

[env~] takes an argument for window size, see the help-file. A larger window will make it go slower.

Yan, this is not how [metro] works, the right inlet is used to set the time between two bangs. Try something like this :

[loadbang]
\
[metro 10] [VU METER]
| _________|
| |
[f ]
|
[send VU]

So the output of the VU meter is stored in the float atom, each bang from [metro] will send it to your app.

Thanks for the tips guys! - this worked perfectly.
