Overview

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

This snippet can be self-signed.

Preconditions

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 =
   CMdaAudioPlayerUtility::NewFilePlayerL(aFileName,
                                          *this,
                                          EMdaPriorityNormal,
                                          EMdaPriorityPreferenceTimeAndQuality);

MMP file

The following capabilities and libraries are required:

CAPABILITY NONE

LIBRARY BassBoostEffect.lib

HEADER bassboostbase.h

Source file

First you need to construct the reverb utility instance:

iBassBoost = CBassBoost::NewL(*iMdaAudioPlayerUtility);

To set the bass boost on, you just need to call the following two lines of code:

iBassBoost->EnableL();
 iBassBoost->ApplyL();

To set the bass boost off, just call following line of code:

iBassBoost->DisableL();
