Hi, In symbian_sound.cpp audio is recording using *CMdaAudioInputStream. *And if i talk from one hand apart of the microphone it can capture voice. My question is if i want to capture voice like normal phone call that is from the small area of the microphone what i need to set in the code. I have checked using SetBalance()<http://www.symbian.com/developer/techlib/v70sdocs/doc_source/reference/cpp/MMFClient/CMdaAudioInputStreamClass.html#%3a%3aCMdaAudioInputStream%3a%3aSetBalance%28%29>, SetGain()<http://www.symbian.com/developer/techlib/v70sdocs/doc_source/reference/cpp/MMFClient/CMdaAudioInputStreamClass.html#%3a%3aCMdaAudioInputStream%3a%3aSetGain%28%29>, function but no expected no result. N.B. I think this is why i am getting cracking sound in the other end... -- S. M.
