same in the standard version

very nice

I assume there are files available somewhere in cyberland as well

You bet.

Doug:

Most likely - in fact I wouldn't be surprised to see a number of well known international venues being "swept" to create CRs.  Carnegie Hall would be a probable candidate, but there are lesser well known halls that have superb acoustics that could be utilized.

In the drop down menu for Reverb in PT Pro, there are a number of built in Convolution Reverbs (Clean Studio, Jazz Studio, Dry Room, Small Hall, etc), but the last selection is entitled Use WAV Impulse.

Or this require many thecnichs and hard work ?

But a room can be very complex, especially if you want to work with 5.1
A complex room can have different materials, walls textures.  So the reverberation that come in the front can be different than the one from sides or from the back.

If you have a sound source in that room and some microphones then yes, the sound will take many complex and interfering paths from the source to the mics, but it still ends up as a few channels of recorded waveforms. You can record the response from a test signal (frequency sweep or whatever) and it should be the same every time you do this. This recording has enough information in it to work out what you would have recorded if *any* sound had been produced by that same source. In practice, there are limitations and reverb implementations may differ in CPU cost and quality, but the results can sound damn good!

The math behind it.

Basically - you get a frequency response of a room by recording either an impulse train, or a sine sweep throughout the audible frequency range, then deconvolve that signal to get the impulse response file, then use that file in a convolution reverb to superimpose the frequency response of the room to your signal.

That's the good thing about using convolution ir's for the reverb: they capture the actual complexity of the room, whereas a reverb based on just calculating the size, material, and damping of the room can't. Or am I misunderstanding your worries?

Supose someone want to recreat the natural reverberation of playing on the Notre Dame Cathedral.

I absolutely love 2caudio's Aether (also check out their simplified, but still amazing "Breeze" version):

By far it's the best I've ever tried (I use it within Sonar X1) for too many reasons to count.

thank you
but i already buy MultiBandConvolution from MeldaProduction and i am happy with it...

Wow, you must be the first one i've heard of who dislike this reverb !

...ok

so i am lucky to have good ears to be able to make difference between a good reverb and a better one

my choice go to MMultiBandConvolution (35€)
and the sound of Pianoteq  is wonderful with it (and all the orchestral instruments too)
