The RME Digi9636 should do its job 🙂 (and after a while its "cheaper" ). How is it possible to expand the channels?
You ment this card, right? http://www.rme-audio.de/hammer/d9636.htm

The RME cards use the ADAT interface. It is an optical interface (TOSLINK) but it transfers 8 channels or 4 stereo channels. The Digi3936 has 2 ADAT in and 2 ADAT out = 16 channels in and out. With the expansion card you can upgrade to a Digi 9652 and you have then 24 channels in/out.
The advantage is that a PC is also ground isolated (at the signal lines).
IMO the cheapest solution to connect to the audio system is to use the Alesis AI-3 AD/DA-converter with ADAT interface or the Alesis AI-4 AES-ADAT-AES digital converter (I use the AI-4, so I do not have experience for other AD/DA-converters with an ADAT interface. But there should be more than one as ADAT is quite often used in recording studios).
I am using RME ADi-4DD for the conversion between AES and ADAT. Sounds pretty good. But some claimed that RME ADI192DD is even better. The latter is also a sample rate converter too, if you believe in SRC!
Ahhh ok i need a AD/DA-converter, thank you 🙂 .
Alesis, i think , is one of the inexpensive and hopefully good solutions ...perhaps there is something in DIY.
So Uli you are now in this forum, would you present some of your personal work (f.e. your DIY-Speakers)? I would like to know with which components is the accourate developer listening to his music 🙂 .

Another question: How are you controlling the Volume?
At the moment i am using a Behringer DCX and because of S/N and the "digital-thing" i have to control the Volume after the XO (f.e. with AV-reciever or DIY-multichannel preamp).

Hello all!
I've spent some time reading through the first 6 pages of this thread and will continue reading after this post, however, maybe someone can help me out before I make it to the 61st page...lol
I'm interested in doing all of my audio processing on a single PC.
I don't care about video or surround sound.
This is going to be in a car.
I will be running a 3 way set-up up front and either a single or dual sub set-up out back. I'd need the ability to add more channels later (as in for a set of center drivers)
I'm in need of
31-band 1/3 Octave EQ
Cross over functions
Time alignment
Phase adjustment
Being able to run a RTA on it would be even nicer.
I'm seeing the Wave set-up mentioned in the first thread as being able to do XO functions, but I see that it's titled as an EQ. This is confusing me a bit. Does the wave plug-in allow for XO as well as EQ functions?
Anyone have any input that might be able to help me out some?

My system is a full digital system (ok, the speakers get analog signals). 🙂
I use three signal sources (CD-Player, DVD-Player, SAT Receiver), but I run mainly the CD-player.
Marantz CD17 mkII, tweaked with L-Clock
to
Genesis Digital Lens (old jitter treatment, AES output)
to
Apogee Big Ben Jitter treatment (used also as input switch between sources)
to
Alesis AI-4 AES-ADAT converter
to
RME Digi9636 soundcard (built into drive- and fanless PC [FuturePC] with BruteFIR on a memorystick)
to
Alesis AI-4 ADAT-AES converter
to
Apogee BigBen to tweeter amp TacT M2150
and to
mid driver amp TacT S2150
and to
bass driver amp TacT S2150
Speakers: DIY with B&W FST midrange driver + ScanSpeak Ringradiator + Woofer W210 TacT
Cables:
DIY Cat7 digital interconnection
DIY silver foil cable (...cable cookbook ..) for tweeter
0815 speaker cable for the other drivers
Optimization with acourate:
Bessel filters 10th order linear phase, subtractive appraoch
driver linearization
time alignment
room correction
See tutorials + white paper at www.acourate.com
Ok so far?

Why center drivers, when you don't wanna have surround it's completlely unnecessary
@ Uli some pics and i won`t bother you further ^^
and is it possible to run music and bruteFIR on the same system...2 AD/DA-converter are a little bit expensive and despoiling a lot amount of space
This is rather simple with the digital amps. They are connected together by a serial cable. Thus the remote control is controlling the volume of the master amp and the salve amps follow exactly.
Benefit: the PC output is always with full resolution. Even the amps run with full resolution first as the power voltage at the output stage is varying dependant on the volume. If the signal is then below a certain level the digital signal is also reduced.
With analog amps you have two chances:
Volume control with the soundcard. This influences the resolution.
Or attenuation behind the soundcard and before the power amps.
Are the TacT amps this good? (just a question without reffering to XOs)
The amps have their own XO
The amps have their own XO
No, I do not use the inbuilt XOs.
TacT is using multirate filters with the room correction system. And they have a similar structure with the amps. So the basic firmware has a filter at 3 kHz samplerate with 2048 taps. This means a resolution of about 1.5 Hz. For some reasons the filter can be used up to 350 Hz max.
The next firmware is 96 kHz with 1024 taps. A resolution of 90 Hz. And then there is an intermediate firmware (not officially supported but distributed by the French dealer) with a filter 12 kHz and 2048 taps.
It is said that the intermediate range is good for 350 Hz to 2 kHz and the high range starts above 2 kHz then.
I had JBL 4-way speakers before with a driver 1 kHz to 4 kHz. So the high filter does not go down very well to 1 kHz (remember the 90 Hz resolution) and the medium filter does not go up very well to 4 kHz.
As the filters are also restricted to be minphase filters I have disabled all filterws in the amps and I use my own XOs together with BruteFIR.
Anyway the amps IMHO are ok. Today they are sold already quite cheap. My assumption is that TacT wants to get rid of the old batch. They are worth the money, especially in combination with a PC based correction.
I have published some pictures at

It should be possible to run BruteFIR and some player together on a Linux system. But I'm not a Linux expert.
But you can also run Foobar with the convolver plugin or the Windows Media Player with John Pavel's convolver or a Squeezebox with the Slimserver convolution plugin. Or you can apply the filters in the simplest case to wav-files with acourate.

The actual price for a M2150 is 1800$, for a S2150 is 1600$ at tactaudio.
If you like to get the price in € you should ask Jean-Yves Kerbrat, the French distributor. You can ask Dirac too, www.dirac-france.com
you can also use T-amp or UCD as your amplifier. They have rave review and I have both. Sounds very good and doesn't cost much . But then you need DAC
Brutefir filters
Uli,
I like the way you have separated the crossover, driver linearization and room filtering in your Acourate tutorials.
But how is this processed in Brutefir? Do you load separate filter files for each task into Brutefir, or does Acourate compute one filter file for each output?

Center 5" subs. With no other place to put them, they would need to go behind the center console. Putting them in the doors would pull the stage too far back. With mid-range drivers in the kicks, it leaves no where else to put them.
Thanks for the concern though.
Does anyone have any possible input for me?
