Stop multichannel measurement while is measuring

[Lba]

Hello! I am doing a multichannel measurement, but when I have to measure more than 2 channels this sign appears. The board is always on and receives and sends activity information. Why could this be happening?

It's a bit hard to see what is happening as your image only includes a small piece of the Measure dialog, it would be helpful to see all of it. When you say "when I have to measure more than 2 channels" what do you mean? A sequential channel measurement? A multiple input channel measurement?

Hello!
What I'm trying to do is measure 16 speakers sequentially, in this case I was testing with 6, but the same thing happens when I test with 2 or more speakers.
The screen is this (apologies for the angle of the photo)
When doing the measurement sweep, there is no input signal in the input box, but the signal enters the microphone (I can see it with the board controller)

The interface driver doesn't seem happy. Try setting some "between delay" for the measurements (same place you select the channels).

 

[Lba]

What does doesn't seem happy mean and why? Setting some "between delay" will decompress the soundcard?

 

[John Mulcahy]

Getting no data means something isn't happy. I have no idea what or why, but a difference between individual measurements and sequential measurements is the time between them, so allowing some time may help.

 

[Lba]

Is there any option to add time between measurements?
I wouldn't be finding it...

 

[Lba]

Sorry I found the way to add time between measurement, but is not de solution.
Sometimes measure up to 6 channels, Sometimes only 2.
Look like pretty random

 

[John Mulcahy]

Is it reliable when you make individual channel measurements? Might have to do them one at a time.

 

[Lba]

I ended up doing the measurements one by one, but I would need the practicality of sequentiality.
Speaking of practicality, is there a way to export all the impulses without the silence prior to the impulse? Configure something to export everything starting from the first spike.

 

[John Mulcahy]

Sequential measurements are just a series of individual measurements, perhaps more time is needed between them?

You can choose to apply IR windows before export, in which case the export will start at the beginning of the left window, or to place t = 0 at a specific index in the file. If the measurements were made without a timing reference t=0 will be at the IR peak. It is nearly always necessary to have some data before the peak.

I add up to a minute and the same thing was still happening.

(Thanks for the export data)

I add up to a minute and the same thing was still happening.

OK, I have an idea of how to fix it. I'll send you a message through the Conversations system with a link to a test build.
