A how to for a PC XO.

Hi Shin,

I understand that if I want to use the same computer as playback source and as convolution using Convolver, I need to route the output of the program like DVDPower back to the input so that Convolver can get the signal. I am planning to buy RME AES32 which has 16 channels out.

If I use 5.1 playback, say AES 1 -6 which is than route to AES 1-6 input. (6 channels are used to route back) and I am left with 10 channels for convolver to use as output (AES 7-16). Am I correct?

Some RME cards such as fireface800, HDSP 9632 have internal loopback. You can access this in totalmix matrix mixer and hold CTRL then click the tab at the bottom of the playback channel you want to loopback. However I'm not sure about the AES16 since I never used that card before, I do know the HDSP 9652 doesn't have this feature and that's digital card too.

If it works, you keep all your input and outputs. If not then you have to get jack working or settle for 10 inputs and 10 outputs.

Email RME and ask before buying so you know what to expect.

I'm working on a guide to Acourate. Its written from a users point of view and is easily accessible. For anyone who owns Acourate or is interested in what offers then it may prove useful.

Its not finished yet but I would like if folks who do download could read through, spot any errors and email me so I can update.

Download is PDF and ~7Mb:

ShinOBIWAN,

It looks like it will be quite helpful. I am not using Acourate yet. I plan on replacing my EAD surround processor with a pc based system, hopefully, in the coming year and will likely use it.

Thanks,
Mike

Hello guys, I am kind of new to the forum here. I am in the process of wrapping up an active 3-way system in my car that has caused me many headaches. I have been starting to research new "small" projects for me to start to possibly replace in my car (Carputer) or the beginnings of a stereo system.

I realize that the learning curve on integrating PCs into stereo systems is quite steep (Especially so in cars) so I want to begin small with most likely a 2 or 3 way set of speakers that I can expand to a 5.1 home theater system and carputer system. I am looking to get a relatively cheap computer for the sole purpose of experimenting with the programs to learn.

What I have learned from "A how to for a PC XO":
I will admit that I haven't been able to read the entire 31 page article yet, but I do believe I got the general gist of what is required. I also have researched the wiki on mp3car.com on their version of plugins. I have learned so much these past few weeks that my mind wants to explode and see what else is possible at the same time!

Both places mention Console and using a RME HDSP-9632, which is what I most likely will use for my system. I guess my first question in my most likely LONG line of questions is what else is required as a minimum to start learning and experimenting?

Additionally, I noticed in the how to here and generally most of the plugins mentioned on that page are a bit pricy ($800 for a crossover) while most of the software on the carputer site is freeware (4-way crossover). I haven't been able to really compare them because I cannot afford $800 just to sample a piece of software, but is there a difference in the quality of the output on the free softwares or are they limited in some other way?

Thanks alot guys for helping me out on basically starting from scratch on this knowledge base! Also, if there is a wiki or faq or something I missed and this is general info please direct me where I need to go to do some more research!

BTW, I tried to make this its own thread but a warning to use the search button before posting came up and wouldnt let me submit my post. Is there a reason for this?

Hallo,
here is my Idea of an "el cheapo XO":

I want to use foobar2000 as mediaplayer to play back my .flac-files with the following two plugins:
- ChannelDivider
- foo_convolve

That way I will have:
- lossless files
- FIR filter with correct phase
- flattened, room corrected response

Here is a nice DRC HowTo:
http://www.file-upload.net/download-..._v1.0.pdf.html

The Audiotrak Prodigy 7.1 Hifi ist the Soundcard I want to use. The two reasons for that are:
- number of channels (8 out)
- internal routing with DirectWire 3.0

I have a Behringer ECM 8000 mic and currently a EMU 1212m here.

The speakers are 2-Way DIY Widerange in Tractrix Horns with 12" Bass:

(my Audio-PC in the middle)

Within the next days I want to buy a 4-Way T-Amp from 41Hz.com:
- Amp9 with Tripath TAA4100A


This should work pretty good, shouldn´t it?

Thank You!

I found a (german) VST Host, which looks very promising to me:
- Free VST Host

Also I want to take a Look at:
- Psycle (Open Source)
- Chainer

How about this for an HDMI card? http://www.auzentech.com/site/produc...theater_hd.php

Yep you don't get full channel count without physical routing and wastage of other I/O's on the card such as ADAT or AES/ABU. RME, MAudio and EMU cards are amongst the best for the windows IMO since these allow full internal loopback and all channels to be used.

Hi everybody,

First post here

Actually there is an internal loopback option on the lynx.
It reroutes 8 of the Lstreams outputs to the following 8 Lstreams inputs.
It is thus usable if you are not already using those steams with an I/O daughter card.

see : http://www.lynxstudio.com/support_docs_result.asp?c=32

BUT, for now, trying to use the feature to use console with MPC via Asio4All, i managed to feed 6 channels to console (the Lstreams "inputs"), see the meter moving in some EQ plugins, but didn't manage to get the sound back to the soundcard outputs!

Anyone tried that?

Hi mycall and welcome to DIYA.

What your talking about here, is this the thing with the jumper on the card PCB? I can't remember, its been awhile now.

If so I used those with the AES expansion so they were taken.

Sorry I can't be of more help.

Hi ShinOBIWAN

Yes that's the thing with the jumper...so it's of no use in your case...

For me it would be usable, as i have no expansion board.

But, i still do not manage to get the audio back to the soundcard output through console using ASIO4ALL...

I just tried with VstHost, and, while i managed to use directly the Lynx AsiO drivers simultanuously with the directsound drivers used by MPC, and managed to get the 5.1 audio in VstHost, i still get no audio at the outputs of the lynx that are patched to the asio drivers...
