The S60 platform has several audio enhancement APIs that can be used to modify the audio experience. One of them is the CEnvironmentalReverbUtility API.

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:

 iMdaAudioPlayerUtility =

MMP file

The following capabilities and libraries are required:


LIBRARY EnvironmentalReverbUtility.lib

HEADER environmentalreverbutility.h

Source file

First you need to construct the reverb utility instance:

 iEnvironmentalReverbUtility =

You can use the following code to query reverb presets:

 TArray<TEfEnvironmentalReverbUtilityPreset> allPresets =

To enable an environmental reverb with a desired preset, simply use an index value for the preset list:

// where preSetIndex is
// 0 .. (iEnvironmentalReverbUtility->Presets().Count() – 1)
