Hi, I would appreciate any idea which can be the CPU-friendly substitute for meter~.

I found out that the behaviour of snapshot~ is slightly different.

[peakamp~] is pretty much like meter~ without the graphics.

and feel free to downsample the process.


peakamp~ is about as CPU-friendly as any MSP object could be. It does a single abs and > comparison per sample in order to find the greatest magnitude sample since the last bang.

the function of peakamp is to get what you would call the envelope of the incoming audio. building a meter or a VU meter or something like that is only one of its purposes. it is a very musical object and fits good to the human recognition.

i've used multislider with a signed-floating-point display(skipping the sample-by-sample abs~ because i can get the same visual feel as regular metering seeing the signed peaks and valleys so this works well enough), but it also uses snapshot~ with its interval set to something close to 100ms, so maybe it's not what you're looking for:

these days, i just use live.gain~ because it rolls the volume control plus the metering into one thing and has a display-interval option as well(there's also live.meter~ which also has an interval option). but it has alot of bells and whistles you might not need too...

depending on the material, snapshot~ will give you total different values than peakamp~ (of almost no relation to envelope or peaks in a worst case scenario)

but what do i know. i use OS9, where both, the meter~ and the peakamp~ object have serious bugs. :/

^true but it's a good enough downsampling which is all you need with graphical representations of audio(peakamp is overkill, might as well use meter~, hahaha)

edit: oh wait, if you all are talking about outputting peakamp~ into number~ then I see now, but I was under the impression the op wanted a graphic like meter~ but down sampled for better cpu(i guess he could also just tweak the 'refresh interval' for meter~ ;)

What is the CPU-friendly substitute for meter~?
