Examples
1. The following example will import a WAV sound file with the dialog. It will also reduce part of the data points and rename the destination workbook name:
a. From the Origin menu, select Data: Import from File: Sound (WAV) or type impWav in command window. This will open the Open wav file dialog for you to choose the import file.
b. Browse to the folder where your data file is. Select the file and click the Add File(s) button. Click OK to close the dialog box.
c. In the impWav dialog box, expand Import Options branch and make sure Add Sparklines is checked.
- Expand File Name Options branch and select the checkbox of Auto Rename.
- Expand Reduce Data Points branch and check Partial Import. Set the Start Row as 5, End Row as 0 (which means the end row is to the end), Skip Points as 4.
- Click Ok to close the dialog and import the file.
2. The following script command imports a WAV sound file (C:\Sample.WAV) without opening the dialog:
- fname$="C:\Sample.WAV";
- impWAV;
3. The following example will use script to import all WAV files under a specific folder (assume it is C:\WAVData\).
- cd C:\WAVData;
- findfiles ext:="*.wav";
impWAV;
