How would you use Jamin????Please
use something else - Jamin got well known as a 'mastering' application 'by default' because there was nothing else around when it was first created. However, according to tests I've done with it (and which others have too) it is fundamentally flawed. It adds significant noise in the presence of signal (even with the strange 'hand drawn' EQ completely flat... more on that later) - so much so, that if the measurements are correct (and I have every reason to believe they are), it amounts to the same kind of quality (reduction) you would get by using an average 'on-board' input to record the audio. So, its not really a good thing for a 'mastering' app to be doing (I have no problem with adding harmonics and or noise etc if
that's what the plugin is designed to do e.g. as part of an emulation etc, but this is just a bug in the way Jamin does what it does)
*The hand drawn EQ - I simply don't see the point - use a multi-band such as my graphical EQ, in which you can 'tune' the EQ curve graphically, but within the confines of a normal set of filter responses, and you will get a much more natural result. I've been fortunate enough to work with some very knowledgeable people in this industry and over a 20+ year career I don't think any of them ever said "You know, what I really need is an EQ in which I can sketch on an arbitarily un-natural filter response and add a lot of weird artefacts to my mix"
I've spent so much time and effort (and my own money) personally trying to build some proper plugins / processing for linux, that I find it unbelievable that people are still stuck with the "Ardour + Jamin" mantra, (one that sadly is often casually repeated by many linux audio 'review' articles if / when they are too lazy to research the subject properly)
I really think its time to move on from JAMIN - it was a reasonable attempt at lashing some very basic plugins together, but its hardly fit for purpose any more.
