Amplitude and level measurements for stereo signal

[test_man]

Hi,

If I input  my attached stereo file into Express Amplitude and level measurement (blue icon) it does not give me output value as an array. I want to measure peak to peak value for both left and right channels. I get only left channel value. (No array)

But if I use amplitude and levels.vi I get array as an output for both channels. So i have what I need but I thought I would just post here anyways.

I have attached my audio file.

Sheetal,

The output of that express vis is of dynamic data type. You need to convert it to a waveform (use the "from ddt.vi") which will then give you the waveform data type. You can then use the "Get Waveform components" to access the "Y" array data.

Post to let us know if this helped out.

Thanks it worked.

If I right click\create\indicator it creates double. but if I create and array on front panel and then connect to dynamic data it automatically convert output to array.

I learned more about dynamic data types.

Thanks.
