Smoothest possible REVERB ??

SubjectSmoothest possible REVERB ??
First the context :
In my latest experiment, I'm dealing with short pulses (spikes) of sound
(like 50 - 100 ms) 

Then the problem:
I need a long reverb that is at the same very, very smooth reverb on this,
so that the pulses do not reverberate in the
typical grainy, echoey reverb..

I've found nreverb somewhat insufficient for this....

Anyone ?


David.

I struggle with the problem you describe, and what I do is using my ALLTIME
FAVOURITE sample editor :
CoolEdit Pro !!!!!

I can't recommend enough that particular program !  CoolPro is not just a
sampleditor, if you're a creative soul, you can use
it as a synthesizer, while it actually isn't build for that at all !
CoolPro just has ALL the features a sounddesigner needs all packed
in a very steady fluent environment :  it has all kinds of filters, even
arbitrary order Butterworth, Chebyshev filters etc, extensive
Equalizing, Dynamics processing (for your problem !), Stereo Flanger,
Stereo Delay, Stereo Echo, even REAL convolution !  
And if not enough : a 64 track non-destructive multitrack
recorder/arranger....

Coolpro is almost the perfect paintingbrush for the sound artist !

After this commercial, now your problem...

What I do is filtering the WHOLE finished stereo file that resulted from
Csound on low unaudible frequencies : highpass 60Hz with
a 15th order Butterworth, they unnecessarely occupy "space" in the -32767
to +32767 range, so after filtering you will have
more "room left" for boosting up volume and dynamic processing....


David.

I find all of these reverbs beautiful.
Maybe try rev4 or rev 5.

I add a couple of menu entries to the tools bar (Customize->Tools). E.g. to compile your source code: Menu Text: Compile CSound Command: c:\csound\bin\csound.exe Parameters: -o $Basename.wav -W $Basename.orc $Basename.sco Initial Folder: $FileDir Check the "Capture output" and "DOS command" flags. E.g. To play your compiled .wav: Menu Text: Play CSound Command: c:\winnt\system32\mplay32.exe Parameters: /play /close $Basename.wav Initial Folder: d:\sounds You can assign shortcut keys to these menu entries, so in order to compile you only have to press 1 key (do this in Customize->Keyboard) You can do the same for the help file, which I find very usefull, as you can select a keyword and then press your shortcut and the help file will be opened right where you want it. Hope this helps.

If you want a really *authentic* TB303 sound then by far the easiest way is to get ReBirth from http://www.propellerheads.se/home.htm Of course, excellent though ReBirth is as a 303 emulation, you won't get the control and flexibility of Csound. It'll be a helluva lot quicker and easier though :) Matt ---------------------------------------------------------------------------- Matt Southall - AARG http://www.psyc.nott.ac.uk/research/aarg AI Group, Dept. of Psychology, University of Nottingham, Nottingham NG7 2RD. email: mjs@psychology.nottingham.ac.uk, tel: +44 (0)115951 5151 ext. 8311 ----------------------------------------------------------------------------

Last month, I tried using convolution for reverb for the first time. I
used an impulse sample from Howard Fredericks's site
(http://wwwvms.utexas.edu/~fredrics/isrc.html - I used the Domkyrkan
sample). The results were quite beautiful - certainly so in comparison to
sending sharp-edged sounds through nrev. I attained a wonderfully long,
perfectly clear reverb tail. 

I haven't used convolution for a complete piece yet, but the downsides
I have seen thus far are: it takes significantly
longer to compute and you don't have the kind of control over reverb
character that you do through conventional reverbs - unless you
dynamically choose different impulse files. Handling the
delay correctly is an additional burden. 

Since I work through Common Music to make my sco files, I've setup my
Csound instruments and Common Music object-types so I can do all of my
rough work using nrev and then quickly swap to convolution for my final
product.
