No more emulations.

I wanna purchase something completely Andrew Simpler.

Something born from all his knowledge and experiences.

Something he would dream of making.

I wouldn't mind if he make a plug-in version of Kim Kardashian.

What, a completely useless plugin (with a nice GUI) that is inexplicably popular?

Well something along Distressor/Fatso with Andrew's twist!

She is not a plugin, but a plugin host.

Does it mean that you plug... and play ?...

Hey andy,

I have a question about the attack time parameter of The Glue.

According to this:

Attack Time is the amount of time it will take for the gain to change a set amount of dB, decided by the manufacturer, very often 10 dB. For example, if the compressor's time constants are referenced to 10 dB, and the attack time is set to 1 ms, it will take 1 ms for the gain to decrease by 10 dB, and 2 ms to decrease by 20 dB.

http://en.wikipedia.org/wiki/Dynamic_range_compression

What is the reference value at the Glue?

Cheers,
Doc

I have done a circuit model so it all comes out in the wash from the values of all the individual components, but I did have a look at it briefly during development and measured it as being a 10%-90% time constant value as described here:

http://en.wikipedia.org/wiki/RC_time_constant

So to actually measure this you are best off pumping in a test waveform and looking at the results. I use a 12 kHz sin wave of around -13 dB, then have a chunk of it at -1 dB, compress the signal to around -8 dB in the sustain section, and look at the resultant shape of the attack and release. Here is such a .wav file I use:

http://cytomic.com/files/forums/attack-release-test.wav

And here is the result with The Glue set to 30 mS attack, and 0.6 S release with ratio 4:

Measuring absolute time taken to reach a certain number of dB compression seems a bit odd to me, since it is only the relative amounts that should matter, otherwise you will have a different attack and release time for different ratios and different knees.

Hey andy,
thanks for your reply, although this seems a bit too deep for me

Does this mean, that if I set for example 10ms attack in The Glue, it always takes approximately 10ms to reach the max gain reduction for every possible gain reduction amount?
While in reverse a compressor with fixed reference values would be "slower" at higher gain reduction amounts(at equal attack times)?

I will try the test you described; could be handy doing this for all of my comps.

Cheers,
Doc

Yes, that is about right. So if your signal was at a level of 50, then suddenly jumped to a level of 100, then once the compressor started working 10% of the total amount, it would take around 10 mS to compress to 90% of the total amount. So for a ratio of 2, the final level would be around 75, so the 10 mS would be the time taken to travel from 97 to 77.

I don't know any compressor that behaves like this, but if there is one then by the article you posted from wikipedia it would take a different amount of time to reach the destination for different levels of total compression, since the measure was time per dB compression, not a percentage of total travel.

Using a test waveforms is the only way to measure the actual attack and release curves between compressors since they all have different markings and behave differently under different conditions. You may need multiple test signals to get an idea of what is going on since some compressors also change time constants depending on audio content. This is the case with the "Auto Release" mode on The Glue.

I think the most important thing to take out of how hard it is to measure all these things is that, unless you are doing some specific modelling or comparison tests, you are probably better off spending your time using an effect and getting to know how it sounds on different material. You should always adjust the settings of effects till you like what you hear, don't take too much notice of the numbers on screen unless you want to recall a specific setting you liked before.

thanks again for your detailed answer

I think I get it now.

Of course you're right; at the end of the day the actual behaviour and sound matters and not the labels on the GUI.
As to me it's more about comparing different plugins and their behaviour to prevent redundant plugins in my vst folder

Cheers,
Doc

News: an update for The Glue now available that will hopefully fix not just some cpu spikes that ProTools users have been reporting, but also help with all hosts. I've stress tested it all at my end but I've had limited user feedback, so please let me know how it goes for you:

The Glue updated to v1.1.4
* New: smoothed Threshold, Makeup, Range, Mix, and Sidechain HP controls so no pops, clicks, or zipper noise when adjusted from gui or automated
* Fixed: removed CPU spikes when drawing the graphical user interface on Mac * Fixed: removed CPU spikes on first play, and when switching oversampling amounts
* Fixed: preset menu not showing with some hosts on PPC
* Fixed: reduced memory footprint with large oversampling amounts with large host buffer sizes
* Known issue: you cannot use both the AU and VST version at the same time in hosts that support both (eg: Ableton Live or Studio One)

Thank you Andy! Best compressor gets even better!
