The S60 platform has several audio enhancement APIs that can be used to modify the audio experience. One of them is the CSourceLocation API. This API makes the audio source's location for the listener appear to change.
This snippet can be self-signed.
The audio player must be fully constructed before constructing the instance of the API. This can be done with the following lines of code:
The following capabilities and libraries are required:
First you need to construct the reverb utility instance:
iSource = CSourceLocation::NewL( *iMdaAudioPlayerUtility );
To set the source location effect on, you need to set the X,Y, and Z coordinates for the source, and then enable and apply the effect to the player.
You can also and a 3D effect by using a timer that periodically changes the coordinates of the effect.
To set the source location effect off, call the following line of code:
