re: ccernn and caco

it all seems target specific for the performance tests looking at the results you have reported.
in the last zip i have compiled with the official mingw 3.4.2 build for the win32 dlls as it seemed the most efficient.

i have the mingw 3.4.2 builds running just a little bit slower than the original msvc build (3.4.2 = 3.6% cpu for one instance, while msvc around 3.4% cpu)
the strange part i guess comes when i compile with the more recent mingw-gcc-4.4.1-tdm and mingw-gcc-4.5.0-tdm (which are supposedly better). but these compilers generate code that is almost 2x slower.

i have tested a lot with 3.x vs 4.x for basic arithmetics (+ trigonometry, prngs etc..). the 4.x series have been dominating the performance test in every aspect.. however i have noticed that most of my test code is pretty much plain c. i have a suspicion that one of the main factors involved here is related to c++ code (as mverb is).

but also perhaps the most major factor could be that -O3 level is different between the 3.x and the 4.x series. i think this could come down to a single flag...some more test are required.

i have recently shared a report with ccernn for a possible compiler bug with mingw 4.4.1 that will generate bogus code if math.h - tanf() is used on a negative number and only in certain conditions (such as -msse -mfpmath=msse). such issues are complicated and difficult to debug, unfortunately :\

Thanks ccern, I have added the Linux versions to my website so the latest versions for Windows VST, OSX VST and AU, and Linux VST and LADPSA can now all be downloaded from www.martineastwood.com

To keep this thred on topic about MVerb, I have started a a new thread in the dsp forum about compilers, msvc vs mingw etc as I would like to continue that discussion and I am sure other people there would be interested in your findings

Just a quick note to say "Thanks!" to Martin, ccernn, and lubomir. I'm always pleased to see new stuff for Linux, and this is a sweet reverb.

Best regards,

dp

Great plug, great thread, a big thanks to all and maybe more development in the Linux world.

Hi. Thanks for this great plugin.
Is it possible to get a version without GUI?
Thanks.

Hi gemada,

the original Windows version I released without the GUI is still avilable Here

Just tried it and I must say it's the best free reverb I've tested so far. Really smooth, natural and low CPU.

Thank you very much for this one!

Has anyone attempted to build an x64 native version of this?

I have been given an x64 LADSPA version (Linux only), which I will upload when I get chance

I'm glad *some* platform has it x64 but I'm on windows.

Yes, a x64 version for Windows would be great

here is a debug, vst build of mverb for 64bit windows:

http://dl.dropbox.com/u/1627980/axon/mv ... ug-x64.zip
(1.6mb zip)

if the plugin crashes on your machine please report:
- cpu model
- windows version
- crash log
- does it crash only in specific hosts
- etc

this will be very helpful to us,
thanks.

ps: note that this debug build is around 28 times larger and 2-3 times slower.
