Hi Scott,

OK, I posted an audio meter demo that some of you may recognize from
RevConWest.  This stack shows a few ways to track the output from a  
player
object and display it visually in 3 different meter displays.   
Execute the

following line in your *message box* (this is not a browser link):

  go url "http://www.tactilemedia.com/tmpanel.rev";

This will open our demo player, from which you can choose Audio  
Meter Demo.


PLEASE NOTE
You must provide the following:
- QuickTime (installed)
- an MP3 or other music file that QuickTime is capable of playing
- Enhanced QuickTime external from Blue Mango Multimedia
<http://mangomultimedia.com/developer/revolution/enhancedqt.html>

Place the external in your Rev folder, restart Rev, and you should  
be good

to go.


JUST WONDERFUL!

Not that i would be surprised ;-)

RR really should incorporate Trevor's great external to the Rev  
distribution!

OK, there is no QT for *nix, but what the egg! :-)

Wish I could tell you.  I've asked this on the list before and some folks
have offered suggestions, but none of them has proven reliable (apparently
the location of the tags can vary within the file).  I gave up on tags for
now and use the filename instead.  You can see an example here in a two
channel player/mixer toy:

  go url "http://www.tactilemedia.com/download/happymixer.rev";

Reminder: QT and EnhancedQT external are needed to run this stack (also, any
recent version of Rev that supports deep masks).

Re: VU meter

[Bill Marriott]

Well I dunno about PPM or VU yet, but the first thing I did to the stack was

setRetro tChannel,tValue

instead of passing N, as N is a value 1 to 10

and

set startAngle of grc ("needle" & tChannel) to 100-(N*100/255)+39

in order to give the "analog" meters a cooler look :)

nice stuff.

Glad the stack worked worked for you Mark.  If you mean changes in terms of
averaging then yes, these meters are really more like PPM (according to the
article you cite).  The script simply grabs the levels provided by QT every
so many milliseconds and resizes a graphic to fit a designated scale.  I
don't think it would be hard to average the numbers over a period of time
but I'll leave that exercise up those who are interested. :-)

Glad to hear it does work.  And yes, I had forgotten about needing the beta
version (I started working with meters much earlier this year).

Re: VU meter

[Mark Smith]

I had the same problem (Mac OS 10.4), with v0.6 of the external,  
downloaded v1.0 beta and all was good. BTW, I installed it as a plug- 
in, as Trevor suggests in the docs...

Hi Bill:

No I think the problem is simply an omission on my part -- I neglected to
consider cross-platform reference to the DLL.  You're on Windows yes?  I
just updated the externals reference on the demo stack.  Quit the demo if
you have it open and relaunch it.  This should correct the problem, but if
it doesn't, let me know and we'll work it out.

Thanks for catching this.

Re: VU meter

[Bill Marriott]

Scott,

I downloaded both the released version and the beta version of the Enhanced 
QuickTime external, put the DLL into the Rev app folder, and tried to run 
your VU stack. It reports, "can't find Handler: qtInitialize" no matter 
whether I use the released of beta version of the external.

Is there something I am missing, or perhaps it's not compatible with 
QuickTime 7?

Hi Liam:

I know one way to do audio meters which requires the use of a player object
and Trevor DeVore's Enhanced QuickTime external.  If I remember correctly it
may only provide 100 units of granularity but measures left and right
channels separately.  If you think this would work for you, I can try to put
a sample together, but otherwise, you may need to look for someone to build
an external.

VU meter

[liamlambert]

I have been working on a project for sound cuing and it is up and  
running with some help from from this list thanks again every body.

Now I would like to add a VU METER  to the project.


Meters which monitor audio levels are typically one of two varieties:  
VU (Volume Unit) or PPM (Peak Program Meters). Though both perform  
the same function, they accomplish the function in very different  
manners. A VU meter displays the average volume level of an audio  
signal. A PPM displays the peak volume level of an audio signal.  
Analogy: The average height of the Himalayan Mountains is 18,000 feet  
(VU), but Mt. Everest's peak is 29,000+ feet



Has anyone got any idea how to go about this is this possible.
