Media_Get ( tag )
Media_Get allows you to check the version of QuickTime, and whether or not sound recording is taking place.
| Parameter | Description |
|---|---|
| tag | one of several values: “Volume”, “Tempo”, “Balance”, “PlayStatus”, “recording”, “quicktime-version”. |
| tag | Description |
|---|---|
| Volume | Media_Get ( "Volume" ) returns the overall volume level for all asynchronously playing files. |
| Tempo | Media_Get ( “Tempo” ) returns the tempo rate of the first file in the asynchronous playback queue. |
| Balance | Media_Get ( “Balance” ) returns a value between -1 and 1 representing the balance between left and right audio channels during playback. |
| PlayStatus | Media_Get ( “PlayStatus” ) returns “1” if if anything is in the playback queue; otherwise, “0”. |
| Recording | Media_Get ( “recording” ) returns “1” if recording is taking place or “0” when no recording is occurring. |
| quicktime-version | Media_Get ( “quicktime-version”) Deprecated. For backward compatibility only. Returns always version 10.0.0 as “1000”. Using Media_Get( “quicktime-version”) returned QuickTime version as a numerical value. For example, if QuickTime 7.5.3 was active, the value returned was “753”. |
| Time-Code | Media_Get ( “recording” [; mediaIdentifier ] ) returns current playback position as a time code. If one sound is currently playing back asynchronously, the function can be used with a single parameter only and returns the standard HH:MM:SS.FFF format. When there are two or more media files playing asynchronously, pass a value returned by Media_PlaySound as mediaIdentifier to query a particular playback position. |
