Hi,
Does Jamin have any facility to do a peak hold display where a
second curve is drawn and is made up of the peak values displayed in the
faster, currently existing curve? If so, how do I turn it on? This is
useful when you're trying to get an overall feeling for the energy
across time instead of what's happening at a specific instant.
Also, I don't see (but am probably missing) a way to set the decay
speed of the display. Typical sort of fast (what's there now) medium and
slow. Often the peak hold operates pretty close to the slow curve, or
sticks around permanently until you do a reset by hand.
FYI - right now the Gentoo version is 0.8.0 and there is an error
message at startup about not finding lookahead_limiter_const_1906.so.
I don't know about the sound yet but I must say that the basic tool
compares pretty nicely to the Waves stuff I normally use. I'm currently
mixing a CD and looking at using Jamin for my final version. Thanks for
a nice tool.
Thanks,
Mark

Mark,
There is no peak hold on the HDEQ. There is a peak on the Spectrum
display. I have changed my own default peak color to dark blue so I can
see it more easily. The default is yellow I think.
I have thought about the possibility of doing a slow fade on the HDEQ
display but it is very problematic. I'm using the XOR graphics plane to
draw and erase the curves. I haven't really done anything with a
partial erase in XOR so I'm not sure how to do it. If I were working in
the normal graphics plane (like the rest of the display) it would be
easy. The problem there is that it takes too long to redraw the entire
HDEQ display ten times a second. If I get a clue on how to do the
partial erasure in XOR I'll look into it.

Jan,
Thanks for keeping it in mind for the future.
This sort of stuff goes a long way toward driving you crazy. If you
play with Waves PAZ then you get used to stereo phase meters, peak/hold
stuff, all the goodies.
While I'm sure not everyone can handle the CPU load, on my 3GHz
laptop Jamin is only running about 25% load when playing my wave files
using alsaplayer. I'd still need to add in a 2-channel HDD recorder to
write the output of Jamin (will you make a recommedation?) but that
won't take much CPU. Anyway, I can probably afford the extra cycles.
Hey - why don't you add all this stuff anyway, upset everyone that
who's machines aren't fast enough, cause them to buy new machines and
then take credit for the improved economy? Do it before or after the
election if you have a certain political leaning! ;-)
Thanks!

I've used Steve's phase (jellyfish/goniometer) meter before (in
meterbridge). All you have to do is route the output of JAMin to it.
Or you could route the input to it if you want.

I have been told (but haven't tried it) that Audacity is now JACK
capable. If you get it to work let me know.

Thats more what the Spectrum tab is for, but I've attached a simple patch
that hacks the frequency curve to be slower decaying (tweak dacay_rate to
change the speed) if you want to try it.

You need newer swh-plugins - but not too new, or the version of JAMin your
using wont run. Mea Culpa.

The limiter that goes with that JAMin is broken. I wouldnt use it for any
servious work that has to go hard to the limit point. If you do want to
use the limiter, best to get a CVS JAMin and latest swh-plugins.
