Media_GetSoundInfo ( container )
Media_GetSoundInfo gives you detailed information about the specified sound file, including format, duration, sample size, sample rate, and bit rate.
| Parameter | Description |
|---|---|
| container |
Location of the sound file. |
To pick out specific pieces of information, use the Media_ExtractInfo function.
Because the information returned by this function is hierarchical and indented, it can be helpful to display the returned information with a font that uses equal character spacing, such as Courier.
Commit Record Note
If Media_GetSoundInfo does not immediately return a value, such as after a sound has just been recorded, you may need to click outside of a field or use FileMaker Pro’s Commit Records/Requests script step.
