Hi there, since [vu] accepts a value for Peak Amplitude, is there a way to measure it with Vanilla objects?
Cheers
This may not be the best solution but I did this by reading the DSP block into an array, on every block, and calculating the absolute peak value stored in the array on each iteration.
I've attached the abstract.

As far as Vanilla goes it does seem like a great solution. Thanks a lot for that, seems to do the trick!
But was really hoping for or even asking for a [peakenv~] like object.
I didn't find anything and I thought I wouldn't be missing it if there was, but came here to ask anyway.
Maybe an update to the [env~] object where it could have a second outlet for peaks.
How feasible is that Miller?
Seems there's a bit of a whole here where we can't easily send the peak values to [vu]. I think it'd be nice to have a way.

Hi all -
I've been wanting to add this as an option to env~. Unfortunately the last time I thought carefully about it I ended up geting stuck in design decisions I don't know how to make. But I'll get back to it someday!

Why does it have to be an extra class and why not an abstraction? I consider abstractions more accessible as you can adapt them on the fly. Personally, I'd prefer abstractions (where the performance penalty isn't too huge).
Yo, I attached an abstraction that extracts both, rms and peak level from the incoming signal. The peak output tries to emulate the behavior of VU meters of analogue mixing desks that have some kind of a fall back delay.

By the way - I just looked, and you can save a great deal of trouble using the "array max" object (new in Pd 0.25) - no need for 'until' horror.
(just put the abs~ of the signal into the table).
But "env~" seems incomplete to me if it's only going to compute RMS.

Oh, that is great! Thanks for the reminder, I haven't looked at [array] yet.

Glad you feel how I do :)
But wondering where you'd be stuck at, seems like something not too complicated. Anyway, waiting for it someday ;)
Why not an abstraction in my point of view? Well, looks kinda cumbersome for that particular goal.

well, I assume they can be more efficient, but my only point here is what I said already and that you agree with - peak level should be available, seems like lots of trouble to need to make an abstraction for it. I know there's an external around, but I mean it deserves to be in vanilla.

do you mean that Pd should come with a set of abstractions for standard tasks? because peak-level now *is* available thanks to roman's patch.

So, basically you are saying it is less trouble to make an external than an abstraction? The fact that neither I nor you made an external indicates otherwise.
I know there's an external around,
I give you an abstraction and you say you're still looking for the external? Why are abstractions second class citizens in your opinion?
but I mean it deserves to be in vanilla.
Agreed, but I still have difficulties in understanding why you desperately need it to be a compiled class (I am certainly not against it, though).
Roman
well, lets see if we can get this to a closure
So, basically you are saying it is less trouble to make an external than an abstraction?
Nope, never said it. Not sure why you took it that way. Maybe because I mentioned "efficiency". But that was supposed to mean computer efficiency, and as a response to what I thought was a general question about compiled classes vs abstractions. Not that the discussion was really about that, and, more importantly, not that is was my point at all, as I clearly stated and then shifted to my point after that...
I didn't even feel like moving the discussion that way, that's why I tried not to do it and stick to my point, by the way.
I give you an abstraction and you say you're still looking for the external?
No no no. I'm not looking for no external. I already know about the external, and I even mentioned about it in my sencond message on this thread, when I said I was hoping there'd be a "[peakenv~] like object" in Vanilla. And then I pointed it could come as a feature in a probable update of [env~].
I've been using [peakenv~] and mostly [prvu~], I think they're great.
Agreed, but I still have difficulties in understanding why you desperately need it to be a compiled class (I am certainly not against it, though).
I wouldn't say I'm "desperate"... so you don't need to keep having trouble trying to figure me out. Also, I never even said I "need" this to be a compiled class, cause I actually do not. I'm happy to share my point yet again, but please don't misinterpret/misjudge my words.
Once more, my only point is that I *think* this is an important feature that *should* come in vanilla objects, it deserves to! Maybe as an extension to [env~], like in a second outlet... that wouldn't hurt... and wouldn't even require a new object. Anyway, that's all there's to it. Nothing more...
I think I'm being very clear and straightforward. Not anyone here thought this was a bad idea too (so it seems), now I'm wondering what is all the commotion about... or does anyone think this is actually a bad idea?
I mean, I seriously wonder what's the deal. Pd Vanilla comes with a very limited set of objects, we all know that. I can get by with that with no problem. I'm just pointing how one little thingy could come into the set, and suddenly things get off track to turn into such a debate. I don't know, I suspect there can be something to it... :)
Why are abstractions second class citizens in your opinion?
Maybe if I had ever stated that, I could answer you to that question. What you could ask me without putting words in my mouth is: why do I think Peak Level detection should come as a function in a compiled class in Pd Vanilla, when you can do it as an abstraction or when there's a couple of objects in Pd-Extended that'll do it for you.
Well, I think it is such a basic feature that deserves to be out of the box from Pd Vanilla in an object like [env~], and I guess I'm repeating myself...
Thing is I have very little knowledge in C and compiling objects, so doing abstractions is All I do... I think it's great people like me can get by with them... but you know, eventually some stuff will get you thinking "hmm, this could have already been made available out of Vanilla objects..."
Moreover, I mentioned [vu] (a vanilla GUI) in my first message and how it receives peak level, but no vanilla object does that job. That looks like something missing or incomplete in Vanilla. I really hope to see [env~] handling that issue soon.
That'll make my day and think the world is a better place.
Cheers
