A bit off topic perhaps, but if your looking for examples of the effects of aliasing, you really can't go past the highly amusing VSTi, 'Mr Alias 2', which can be found here: http://www.thepiz.org/mralias2/pro.php

That's what I get for being sure about something
The bendy thing is normal, for "real" analog guitar amps and distortion pedals etc., so unless you can compare the two and see what differences there are, I wouldn't even worry about it. (As far as I can hear anyway, the guitar amp sims are doing what they're supposed to and nothing unusual.)

About the compressor: if I had hardware compressors here to test, that would be interesting. I don't though. I only use compressors ITB. Maybe compare other compressor plugins with similar basic settings?

I did a bunch of DSP compressors, they all do some pretty serious aliasing

Do you have any hardware compressors to compare? I've never tried something like this with one to see what might happen.

I was speculating that analog hardware compressors should not cause aliasing problems because the ADC will filter out any ultrasonic frequencies that are generated, if any.

Also, hardware units have noise ratings measured as THD (total harmonic distortion) which may only refer to the measurement method. But, the term implies that the distortion will be harmonic. Thus describing the saturation that all emulating plug-ins are attempting to mimic. And, which is considered to be non-offensive unlike aliasing.

Yes, aliasing is unique to digital, as I guess there's no sample-rate with analog. Though I don't see how (digital) hardware would be any different in regards to aliasing, unless it simply ran at a higher sample-rate.

I think digital in which aliasing has been eliminated would be superior to analog, as there's less overall distortion (if I want distortion, I'll add it.) Of course that's more a matter of opinion. I'm into super 'clean' sounding audio. E.G. I'd like my drums to sound the same as when I'm standing in a room and listening to them (I know, unattainable).

I'd like to start working at 88.2 project rate (ITB stuff with soft synths), I noticed on quick testing that a few of my plugins sound much better than at 48, I wasn't really expecting such a massive difference in reverb soundstage for example.

However not all plugins seemed to handle 88.2 properly, so I wonder if there's any sort of tester program or a standard test procedure for evaluating plugin behaviour?

The human auditory system, as well as the gases we tend to hear pressure waves propagated through, are far from being a "clean" system. Especially the pumping compression given to something as loud as a drum kit in a small room!

There is often a huge disconnect between what we think things sound like and what they actually do. Not many people record drum kits using a binaural dummy 10' away... mainly because a blend of different mic positions sounds better, and "cleaner" if that's what you're shooting for.

point is, that we dont hear with our ears. we hear with our brains.

the sound waves are coming in into the ear and are interpreted in the brain. emphasis on "interpreted". and this interpretation depends on lots of factors, that a music producer cant take into account. nearly none of them.

so I am not posting again the Monty Montgomery video and the Lawo-papers and Ethan Winer explanation and so on and on and on but I am saying it again: there is no point to go beyond 24bit/44.1kHz. that is proven time after time after time but there are some, who still dont know or dont want to know or to be the kickass-wiseasses at every cost. ah, yes, and there is the snakeoil-industry...

everything else is lying into the own pocket or a bias towards "bigger numbers are better".

This is true.

This is why, when people here a drum kit in a room these days, it will tend sound more like drums on a record than what the drums actually sound like in the room. Expectation is a huge part of how we perceive sound.
