wav to aac conversion interruptListener not calling in ios

Question

I am doing an audio based app in which i am converting a wav file to aac format. Conversion working successfully but interrupt listener not called while conversion even if one call came... I am initialising audioSession and handling interruption in main(). Interruption listener working in another part of application like recording and playback. Anyone can help me, please?

Answer 1

Finally I got the solution for this problem. I had used audioSession category

kAudioSessionCategory_MediaPlayback

earlier for AAC Conversion. Now I changed it to

kAudioSessionCategory_AudioProcessing

So it is working good now. Interruption listener method is called perfectly while interruption takes place.
