i create the file?

Hello Kevin!

What exactly is the content of the array? Is it waveform data? Is the data-plugin a VI?

Maybe you can post the data-plugin and some sample data so we understand the situation better.

Regards,

Hello Georg,

here some pictures, the first shows the old version of the VI. In this version was used a VI (Snd Write Wave File)

to create a .wav file, but now I want to solve it with a MP'3. As you can see, here i have a float array:

 

To write the data-array into an MP'3, I wanted to use this DataPlugin:

But to use this DataPlugin. i have to open the data storage in form of a MP'3 file. My question: how can i create such file?

I think there are conventions that I have to observed, right? or should I use a dummy file that is copied before?

I hope you understand me. And sorry that the pictures are in German.

Unless you get real crazy in LabVIEW, your best bet is to use some external library and send audio through that.  LAME is one I've used in the past, but not with LV.  Works well.

Hi Kevin,

the Audio DataPlugin supports reading MP3 files, but unfortunately not writing...
