How to read raw signal for spectrogram?

[altenbach]

Is this a LabVIEW question? If so, it should be moved to the LabVIEW forum.

Please provide much more information:

• What kind of instrument?
• How is it interfaced?
• What do you mean by "raw signal"?
• What software are you using?

I have the same question, hope you don't mind that I hijack this thread 🙂

I just want to know how to read the raw bytes. I have attached the wav file(just rename the extension to .wav). Its at 300 baud, so each byte should be 3.33ms but its hard to know where to start and where each separation is.

• What kind of instrument?

I'm using Audcity to view the raw signal

• How is it interfaced?

Its a wav file

• What do you mean by "raw signal"?

raw wav

• What software are you using?

Audacity

Your picture is broken.

have you tried Sound File Open VI?

[deviant112]

its not a picture, its a wav file. Change the extension to wav.

The Sound File Read VI is a plugin/function in labview?

[altenbach]

It is a function. Did you check my link?
