Cytomic 'The Glue' Compressor

[kmonkey]

The Glue doesn't model any nonlinearities of the analogue hardware, which is where most aliasing would come from. in a compressor harmonic generation is minimal. Andy already stated a couple of times that The Glue upsamples sidechain for calculation of the attack phase of process. Oversampling means (apart from CPU overhead) that either phase of the signal will be messed up in the upper band or the process will generate latency. So, for me, asking for a processor that is most transparent, has no latency and uses oversampling is a bit mutually exclusive

Yes but Aleksey at Voxengo seems to done it properly

Oversampling with zero delay is there

Hi Andy

I installed the latest 32 bit and 64 bit versions of The Glue last night.

The 32 bit works fine, but I can't change any of the settings or select the preset menu on the 64 bit version.

I'm on an i7 PC with 4Gb RAM and using Cubase 5.5 on Windows 7 Home Premium 64 bit.

Regards

Steve

Don't want to sabotage thread, so feel free to move mod, but how you finding the i7 processor performance? I'm on Q6670 Quad and really looking to move.

Not really used it in anger as I'm still loading up all my VST's etc. But now that most of them are 64 bit, I'm looking forward to finally moving off of 32 bit.

Hence, why The Glue not working in 64 bit is a problem. (Got it back on topic mod)

OK thanks Steve.

If there is zero delay, what happens to the phase? Feel free to ask Voxengo this question and report back here. My guess, from what little information you have given, is that Voxengo is using a two path polyphase iir filter, and if so it will mess with the phase of the upper frequencies.

Hello to all and hello Andy! I think your compressor is the greatest one among the plugs however i have a complaint. You shouldnot update 1.0.16 to.........1.0.16. Im really confused now because sound is not the same. To me now it sounds more like 1.0.15. something with the tone or attack or whatever , i can feel it. are you sure you didnot change anything else and im having hallucinations?

Sorry about the confusion with the version numbers, I really made a mess! Rest assured that the sound has not changed at all apart from a minor optimisation to the auto release algorithm, but if you are loading old projects I update the settings to match better with v1.0.16. Perhaps it is just compressing less that before because of the updated settings?

Thanks for the bug report, I'll look into it and report back.

I've just tested out the 64 bit vst of The Glue in the Cubase 5.5.0 64 bit and it is working fine on my Windows 7 64 bit Core 2 Duo machine. Can you please email support so we can talk about how we can resolve the issue? www.cytomic.com/contact

so you think its just compressing less?if it is a problem then ok, ill try to live with that. i liked the way previous 1.0.16 worked. matching thresholds in old projects didnot bother me at all.the point is that now it sounds different and i can hear it.

How about oversampling with zero attack?!

Can you please email me a settings file that sounds different to you? If you aren't using auto release then they are 100% identical, I've not changed a line of dsp code at all honest!

If you mean oversampling with no latency, than sorry, no.
You can't beat math.
If you want linear phase, that is.

However, even minimum-phase AA filters I've seen slow down impulse rise-time (usually down to 5-6 samples) so even those have "latency".

Yes, that is correct, you have to choose your poison:

* for a typical polyphase iir you have low delay (like meloco_go said around 5 samples) and messed up phase and higher ringing
* for a typical linear phase fir you have higher delay (depending on quality up around 80 samples) and keep your phase and have lower ringing but also pre ringing.
* a blend somewhere between the previous two

Any way you look at it there is no getting away from some compromise, and you will always have some delay. All soundcards that I have seen use linear phase firs, so when you sample a square wave you see symmetric ringing both before and after an edge.

I'm nearing the end of my demo run. This is an excellent plug-in at a very reasonable price.

For me personally, I'm uncomfortable with the stepped controls and limited setting choices. I understand that that's what this plug IS... so, not complaining.

But I'd be much more interested if the modeling was interpolated into adjustable attack and release settings, and ratio if possible. Perhaps this could be done for a "Glue Two"— with a New School—Old School switch?

Over the years, I often find myself using compressor attack times of around 2ms. So coming to The Glue and finding that my nearest choices are 1ms and 3ms is a bit off-putting.

I think Glue is as good as it can be.
But yeah, I'd like to see something with wider attack (actually I'd like some reaaally slowish attack, at something like 100ms) and release ranges (for that a shorter release would be great, and finer range of settings).
Maybe something Andy would consider after his next plugin.
