question about audio recording

[hawlman]

hi,all
I am a new guy for symbian programming. I want to implement a audio recording software, that can record at 44.1k Hz and save file as a raw wave format. Could anyone give me some suggestions?
BTW, is there already any symbian software with the above functions?

You can record using CMdaAudioRecorderUtility.

iMdaAudioRecorderUtility = CMdaAudioRecorderUtility::NewL(*this);

......

TMdaFileClipLocation iMdaFileClipLocation = new TMdaFileClipLocation(KRecorderFile);

CMdaAudioType iMdaAudioType = new (ELeave) CMdaAudioType;
iMdaAudioType->iFormat=new (ELeave) TMdaRawAudioClipFormat;
iMdaAudioType->iCodec=new (ELeave) TMdaRawAudioCodec();
iMdaAudioType->iSettings=new (ELeave) TMdaAudioDataSettings;
iMdaAudioType->iSettings->iSampleRate=44100;
iMdaAudioType->iSettings->iChannels=1;

iMdaAudioRecorderUtility->OpenL(iMdaFileClipLocation, iMdaAudioType->iFormat, iMdaAudioType->iCodec, iMdaAudioType->iSettings);

.......

put below code in your Record function or in MoscoStateChangeEvent() function

iMdaAudioRecorderUtility->SetAudioDeviceMode(CMdaAudioRecorderUtility::ELocal);
iMdaAudioRecorderUtility->SetGain(iMdaAudioRecorderUtility->MaxGain());
iMdaAudioRecorderUtility->SetPosition(TTimeIntervalMicroSeconds(0));
iMdaAudioRecorderUtility->CropL();
iMdaAudioRecorderUtility->RecordL();

i hope it solves your problem
