LSR
Hey Sonopanic,
That stinks. I know there is also an option when building the send that lets you output to ASIO and then input to ASIO within the same send. I know you mentioned that you had two seperate sends - one in and one out (which I would guess would do the same thing). But, you could try the single send and see what happens.
Sorry I can't be more help. Like I said, I haven't gotten Acourate yet. So, I don't have first hand experience myself.

AcourateLSR is intentionally written to send two signals (left, right) to ASIO outputs and to record in full-duplex mode (at the same time) at one ASIO input (left channel).
Steve,
you can download the program from my website and also try to run it. Maybe you can help Sonopanic. I don't own this soundcard.

Hey Uli,
I was planning on giving your program a shot. I need to clear away some free time for it though. I have a feeling that I'm going to need some this in order to get a good handle on it. It seems somewhat complicated -- which is not necessarily a bad thing -- and I want to make sure that I will have enough time allocated to give the program a fair shot.
Looking forward to it Uli,
Steve

Send to ASIO for LSR to work. LSR doesn't deal with Wave/WDM.
I've had it working with the Emu so its possible.
I'm not around on the forum much these days since discovering World of Warcraft
Hopefully you'll have it sorted but I'll try to check back and see if I can offer further help.

Hey Sonopanic,
I'm using Allocator. It does not have near the capabilities of Acourate. But, it's easy to implement and gives a good intro into computer based filtering.

Hey Shin, good to see you 🙂)
Can you say where the error is ?
I try to save a measurement with acourate Logsweep recorder,
but all i get is a flat line in the amplitude window.
I think, the error is the routing over the e-mu mixer.
I want to record the Mic A, so i have insert a SEND Command
to Asio in 1/2 Host at the Mic strip.
For output i´ve made a strip with Asio out 1/2.
LSR inout seems correct, because the peak meter is green and
yellow. How i manage the record on harddisc ?

Are you hearing sound out the speakers but its not recorded?
If I remember correctly I needed console to route the ASIO playback coming from LSR into the loudspeakers to allow recording.

Yes, i hear sound in the speaker.
I chose Mic-A as input and Asio out 1/2 as output in LSR.
At console, i can only use the wave in and out.
I haven´t seen asio in console...

Hi Uli
good to have you here now and then.
Though almost no free time available for all this, there is a need for me to do the measurements *not* by a sine sweep - but rather by MLS.
Simple background: Neighbours.
A sine sweep penetrates the whole house - or the whole quartier - if done outside. And usually one sweep isn't enough 😉
MLS is not boring - mostly not even noticed.
Any chance to use ARTA measurements or anything else as a impulse respnse creation basis for further processing in Acourate?
I remember having asked you that before, but thought it may be of general interest and hope you possibly could come up with some detailles for procedure as it's more urgent for me now...
You mentioned that there might be phase problems with MLS - IIRC - did you mean phase relation between speakers ?

Console is multiclient. It handles WDM(windows wave) and ASIO simultaneously. You can input or output any type of audio providing there's suitable I/O on your drivers.
Michael,
Acourate can read so far pulse responses in format dbl (double precision float), pcm/raw (single precision float) and wav. You should know.
It would be no problem to read other formats as long these formats are documented and someone is telling me.
For this it does not matter what method you use to get the pulse response. You can run a logsweep or MLS or white/pink noise or single pulses or allpass signals. (If you know about other really nice sounding test signals please tell me).
Logsweeps have some important benefits, see e.g. http://saturn5.com/~jwb/mueller.pdf
But maybe they have also disadvantages for you e.g. by neighbours hating freefield measurements. Then you can of course use MLS as long as the result is a pulse response.
The only problem can arise if the resulting pulse response is e.g. of type minimum phase but you like to get the true phase behaviour.
A requirement for a given pulse is about its length. It should be clear that with a pulse of length 50 ms it is not possible to analyze 10 Hz. So Acourate typically uses 65536 samples which means a length of 1.4 sec at 44.1 kHz. And it is also wise to have a certain number of samples also before the main pulse peak. But you can also add leading and trailing zeros to a pulse with Acourate.
So if you have a given pulse response in a different format you can send it and I can further check.

I have just made a quick check with an ARTA pulse response exported as txt-file. It is easy to import. On my ToDo list.

Arta can export Impulse response as wave file - As far as i remember.
This Impulse response can be measured by sweep, MLS or any other methode Arta supports

Yes, you are right. I have an old version on my computer. The actual version at least can export the pulse response as wav.
Last comment: Acourate reads pulse responses exported by ARTA as wav-file without problem. It may only be necessary to apply some gain as the ARTA data are not normalized to 1.0
Hi Uli,
Acourate can read so far pulse responses in format dbl (double precision float), pcm/raw (single precision float) and wav. You should know.
The LSR builds .tri files.
How could i read these files with acourate ?
I thougt, the LSR produces files for acourate, so imho it is
consistent, that the .tri files can be chosen in the "open" menu
of acourate.

The .tri format is a specific proprietary format for Acourate. Thus Acourate can of course read AcourateLSR files.
I have mentioned the .tri format here before as the question has been about importing pulse responses from other programs

Uli, Henckel - thanks.
I wanted to make sure it works, as I need to buy € 80.- ARTA licence to allow for saving IR files.
An other option would be AudioTester.
AudioTester also has some reputation (at least *I* like it very much 🙂 ) and is fairly spread under DIY people. There is an option to store time domain diagram's as a text file.
Any chance that you implement the use of these text files for further processing in ACOURATE ?
(BTW - this licenece I already own 😀 )
As far as I understand now, the only strict requirement for ACOURATE is that the resulting IR file is "long" enough to allow for precise results in resolution and at the at the lower frequency end.
What MLS sequence length would deliver IR's being roughly long enough for the case of creating 44kHz filters - eg being comparable in results to the log sweep performed by AUDACITY or the LSR tool?

Michael,
ARTA allows a max MLS measurement of 5.46 seconds = 262144 samples length of pulse response. This should be ok.
