ERR (-1929)

[MatthewSHP]

Greetings!

I'm having a problem with LabView 2013. I downloaded a sound measurement program from the internet that uses a SVL Integration VI. The problem is, when I start the program in LabView 2013, I get the ERR (-1929) warning and the program doesn't work. When I tried the program in LabView 2011, I also get the ERR (-1929) warning, but the program works normally. My question is why is that happening and can I somehow get the program to work in LabView 2013.

Thanks in advance!

That error means that the array of input waveforms was empty. Verify that the data source is returning valid data. Are you running an example code from the NI community or something you build from scratch?

[MatthewSHP]

I'm running an example program from the NI website, the sound intensity example program.

It can be found here: http://www.ni.com/example/31353/en/

The problem was that I was working at home and didn't have the DAQ assistant with me, that's why I was getting the (-1929) error. Now that i plugged the DAQ assistant and tried to run the program again, in the 2011 version I didn't get any errors (OK), but in the 2013 version i got the (-1906) error even though i didn't change anything in the code.

It looks like the VIs used in that example are from an older verion of the Sound & Vibration Toolkit (SVT) (2009, five years old!). Some of these functions have direct replacements, but others do not. 

What data are you actually interested in collecting/processing? Maybe I can try to point you to another example. 

[MatthewSHP]

I'm interested in collecting/processing sound pressure using a microphone pair (intensity probe).

I contacted the costumer service in my region (Slovenia) and they didn't have the solution, but they forwarded my mail to the costumer service in the USA. They replied and sent me a completely new program for sound measurements. I'm going tomorrow to my college to test it out so I don't know yet does it work. I can post back when I do.

The program is in the attachment.

The program I am trying to work on is a intensity mapping program which uses the SVL Integration VI. My college professor sent me the program he got from Japan. The program I got from the costumer service doesn't have modules for mapping and I'm not skilled enough in LabView to integrate them in the existing program. So if you have a solution for that I'll be very thankful.

EDIT: The program that i got from the costumer service only measures sound levels, but I need a program that can measure INTENSITY.

[Nathan-M]

What functionality are you trying to accomplish that the sound meter example cannot achieve? You can measure the sound levels from both channels and do the math in LabVIEW to get the intensity that you are looking for. As a side note, did you receive a service request number when you called in to customer service? 

[MatthewSHP]

I'm trying to make a sound intensity mapping program, I already have a program with the mapping modules but that program uses the same SVL Integration module as the Sound Intensity Example - DAQmx program. I have a problem with the sound level program because it is set to work with one channel, but I have a microphone pair. When i try to change that in the code, a couple of wires couldn't connect.

I need help in the program I'm sending you in the attachment, I'm getting the same error with the SVL Integration as in the Sound Intensity Example program.

I did recieve a service request number and I'm in contact with one of the application engineers from Slovenia.

After some talk with our R&D team on this, we're working towards a resolution. You may be hearing from your Slovenia Applications Engineer within the next couple days on this. Post back to this forum if not and I'll make sure that you get taken care of!

Thanks for being patient, we're almose there!
