[LAD] transfer function visualisation
Hi! Is there some kind of JACK-ready tool to draw a transfer function (db/db) of a given chain (last one is something having JACK input and output ports)? Of course, such tool's opportunity to change a frequency of excitation is my main dream :-) Andrew Gaydenko ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-dev

Ehm ... no? And btw transfer functions are only for LTI systems, so such a tool wont work with arbitrary JACK chains. Or do you just want to use it for chains of simple filters and effects? Ah, and such a tool has to be connected to both ends of the chain, to be able to send an impulse through the chain.

CU Christian Christian, You are right, I'm just interested in what does this or that filter/effect do (limiters, compressors, tube-nizers and so on - both software and hardware). Of course, I see, say, attack/release times may be beyond such simple db/db viewer. At any case pseudo-static mode is interesting also. I imagine such viewer having (besides of excitation frequency control) 'min level', 'max level' and 'excitation time' controls. Last one may be rather long (say, up to 20-60 sec).

Although you'd have to do a lot better than double if you wanted to represent irrational numbers in binary form. =) Two 32-bit ints can represent (the non-integer part of) most (not all) irrational values to better precision than a double. The algo to find them is a bit mysterious but very simple. Simple example: 355/113 is equal to pi with a relative error of less than 1e-7, not bad for two 3-digit numbers. It's not difficult to find two 32-bit ints that would be better than a double. So, what's the verdict on this? Don't want to fall into the perpetual beta with known issue trap, I'd like to fix the sample rate issue and crank out another beta ASAP.. I'm skeptical we'd ever actually see a plugin that would use rational sample rate, so I vote double unless: - rational is required for perfect video sync over long time frames - someone can provide a concrete example of a realistic plugin that would require/benefit from rational -DR- ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-dev

This isn't exactly small, but it's pretty cool. I just got a Zoom H4, which is a 2 track handheld recorder. In both live audio and hard drive mode over usb it works perfectly with linux, jack, and ardour. Alternatively to it's built in mics, it can power 48v mics. I hooked up some NT5s to it, worked great. It can record on its own for hours and hours to an internal SD card as well. So far, I'm tickled pink with it.
