Re: Read wav file

Hello pollon,

 

is LabVIEW the software you would like to use? If yes, it is possible:

 

How to Use the Sound Output VIs in LabVIEW to Play Wave Files

Is this what you were looking for?

 

Saluti,

Re: Read wav file

Hi, 

thanks for your support. Anyway I would like to read the wav file with signalexpress and then process it with the sound and vibrationj toolkit

Re: Read wav file

If you want to open @ltheux's example, don't bother. The sound file examples that come with LabVIEW are better.

Re: Read wav file

Hi,

I'm having trouble with playing a wav file.

What I want to do is playing the sound when a boolean originating from a FPGA target is True.

Although I try to play the sound on the top level VI (runing on the computer) I get an error saying that it is incompatible with the current target.

A dummy copy of what I aim to do, but without FPGA target works well. 

Hence I've also tried to 'isolate' the FPGA by playing the sound in another VI that talks inderectly to the FPGA via some global variable - but whatever the configuration I tried it would not work.

What is the reason why the computer is unable to play a sound as soon as it is interacting with the FPGA?

Is there a way around it?

Thanks!
