This project demonstrate how to convert DATAQ's Windaq file to sound file
This VB program has the following limitations:
1) Only one channel can be extracted at a time
2) If the sample rate is not supported by Windows, you may not play it back via the speaker
To try this out, you need to:
1) Download the Dataq's latest data acquisition ActiveX control
2) Download the codes of this VB program.
3) Generate a WinDaq file and name it sample.wdq, or download a sample here if you don't have one around.
4) Place it in the root directory of C:\ (if you use the default path of this sample)
5) Optional: Run Windaq Waveform Browser to study the waveform
6) Run the VB program provided here to extract a specified channel from c:\sample.wdq
Here are some screen shots:
The original WinDaq file opened under WWB.
The first channel is extracted from the above Sample.Wdq and convert it to .WAV file (Sample.wav)
