Hi
guitarix user "funkmuscle" points me to some high quality IR-files,
witch can be used with guitarix or Rakarrack for example, to emulate a
nice Marshal sound. I'm really impressed by the quality of this files.
Redwirez gives away for free a set of the Marshall 1960A, only a
Registration is needed.

OK, you're free to call
me stupid, but I just can't get a decent sound out of IR. I'm not doing something
right, I'm sure. Can anyone, please, tell me how to set up guitarix or rakarrack with
some good IRs? Thanx!

In guitarix it is simple, just load the IR file with the settings
widget, and press run. Okay, most files I have tested before needs a bit
of trim, e.g. a offset of a few samples and a length cut, and possible
setup a gain curve, that isn't needed with the files from Redwirez.
The Ir files brings a kind of Sound colour (reverb or/and cab emulation)
to the output, you need to adjust the settings for the Amp and maybe
some Effects to your needs.

thanks, I'll try these out when I'll get back fiddling with guitar.
As a side note, could someone explain what exactly are IR-files and how
software like guitarix and rakarrack use them to emulate
amps/cabinets/rooms?
thanks,

They are basically audio files, or you can call them "reverberation samples".
If you record the impulse response of a hall, the resulting audio
file, when applied programmatically to a signal, will process that
signal against the "properties" it had recorded.

It's exactly the same thing in boht cases, the only difference being
that reverb IRs tend to be quite long (seconds), while 'EQ' IRs are
usually short (a few tens of milliseconds).
A reverb is just a filter with a very bad phase response :-)
What happens in convolution is:
* each single sample of the signal is replaced by the complete IR,
starting at the same place at the sample, and multiplied by the
sample value,
* all these scaled and shifted IRs are added together to form the
output.
It's a gigantic computation for long IRs, but there are tricks to
accelerate it.

Yes, depending on the setup to produce the IR file it could included
both. Often you have also some artefacts from the signal witch was used
to produce the IR file, witch wasn't the case with the files I mention
above in this thread. I prefer to talk about a sound colour (in non
technical language). The difference between the plain signal and the
signal send to a amp, Speaker, Hall, Coffee-cup, or what ever you could
imagine. When you search the net about Impulse Response Convolution you
will find crazy stuff. You could use it for match more then plain
reverb.

Not only equalization, re/ver/vi/bration takes also a role.

Wow, cool! Thanks for the link, registered right away! G12M-25's,
pfffff, why didn't they use real speakers ;)
Best,
