I appreciate the ideas and confirmation I'm going about this correctly.
I picked up my cable online this morning.
Any advice on best practices for amp volume level and recording level?
I notice the sound levels barely seem to register on Audacity even when
recording levels are turned all the way
Hi,
I'm currently working up to using the Inguz plugin for DRC, just need
to get a USB preamp for measurements. At the moment I am using the
plugin just for EQ. Works great - cheers Inguz.
Anyway, my question There are a few threads at the moment asking

Is anyone else having trouble with connecting the SB to their audio
interface to complete the Inguz measuring process?
I'm using a Tascam US-122 and at this step in the measurement process:
Connect the Right analog output of your Squeezebox to the Right
line-input of the audio interface

Any suggestions where to find the cable

Hello,
I've been reading about Inguz audio correction for some time and am
excited to give it a shot in my system. I picked up the recommended
ECM8000 measurement mic and am looking at audio interfaces now. I know
the audio interface needs to provide phantom power to the mic and be
able to record
To a good approximation: no. The measurement process uses very long
logarithmic sweeps to reduce the effect of background noise and
nonlinearities; mostly, background noise from the room/environment and
nonlinearities from your loudspeakers will be much bigger than from the
mic interface.

Interesting room. I suspect the right-channel nulls really are the
right wall/window. Are there heavy drapes on that window?
There are probably some rear-wall reflections from the front of the
tv/console. I've played with a similar setup (fireplace, not tv) and
some absorption on those front
OK, using the graphs posted earlier (and getting up to date on .Net 2.0)
I was able to generate the filters soft, normal, strong, and no
correction I've loaded the Inguz plugin and EQ, and put the filters in
the proper application data folder. This required 2 start/stops of the
slimserver.

Yes, I did that, but apparently I missed a couple. For good measure, I
also made certain that there was only one checked per file type as
there were several files types which had multiple decoders checked -
not sure how that would affect it...

You bet - especially thanks to Inguz. I do now feel that I will be able
to easily generate new sweeps and filters as I make improvements to the
room itself.
I'll give it a good listen over the next few days and post my
impressions later. Is it worthwhile to run corrected sweeps and compare

You do NOT want to be doing this at a volume level where you might be
clipping! Turn it down with your preamp (or squeeze box, it doesn't
matter). It really doesn't have to be all that loud -- somewhere in
the 75-80db range is more than adequate, according to most sources.

+1. The absolute volume level of sweep measurements doesn't matter very
much, as long as the signal doesn't get lost in background noise. The
relative levels don't matter much either, since each channel is
equalized separately later whatever the absolute level of the measured
sweep.

Absolutely and well-said. Now, would you kindly sit down at at a Mac

I have been playing a lot with my speaker setup in accordance to the
advice on the forums. When I say clipping I refer to the one
frequency in the low end (it rattles the china cabinet), but other than
that, have been pretty careful not to have the volume overly loud. (The

I'm not familiar with Audacity. However, this looks like a time window
impulse response and not a frequency measurement. I could be wrong,
but, well, that's what it looks like. I think you need to be in
another window of your program.
Rattling the china cabinet is not the same thing as
You are probably correct about what that graph represents as well as my
misuse of the term clipping. I was looking at the Inguz website where
it says:
Start recording, and play Stereo Sweep. Watch the peak level in
Audacity as the recording progresses; if the loudest levels are hitting
the top

Totoro - The cabinet is in the other room, and I don't think the mic
will pick it up strongly. It is a very slight resonation that I can
feel in my chest as well as vaguely sense/hear from the cabinet. WAF
will prevent jettisoning that!

Yeah, stupid question - thanks for the patient answer though!
I've been looking at the PC more today than listening to music - not

to 2.0 and see if that is it. Unfortunately I am also going to be
