Recorder Utility not supported?

[djburford]

Hi,

I have already seen several posts on the CMdaAudioRecorderUtility class. So, hopefully someone here can help us with our problem.

We have an application that uses the CMdaAudioRecorderUtility to record speech from the phone microphone and save it to a wav file.

When we build the app using the SDK for OS 7.0 (Nokia Series 60 2.1 SDK) and run the app on a 6600, it operates as expected. However, when run on a 6630, the app pops up a message which reports "Feature not supported". This seems to happen on a call to the RecordL() method of CMdaAudioRecorderUtility.

We thought that rebuilding the app using the SDK for OS 8.0 may fix the problem, but unfortunately this does not seem to help.

Can anyone help with this problem? What exactly does "feature not supported" indicate?

Regards,
Dennis

Did you try the sound example that comes with the SDK? It calls the same function. I tried on 6630, and it worked.

Hi,

I'm trying to create a recording application using CMdaAudioRecorderUtility.

I'm using SDK60_3RD and visual studio2003 . NET.

I'm getting the code to run but in the nokia emulator I get "Feature not supported" every time I reach CMdaAudioRecorderUtility::RecordL or CropL methods.

Can you please help me with that.



My code looks like this ;



_LIT(file,"C:\\myrecord.wav");



RArray<TUint> aSupportedSampleRates;

iMdaAudioRecorderUtility->GetSupportedSampleRatesL(aSupportedSampleRates);



iMdaAudioRecorderUtility->SetDestinationSampleRateL(TMdaAudioDataSettings::ESampleRate8000Hz);

// Set maximum gain for recording

iMdaAudioRecorderUtility->SetGain(iMdaAudioRecorderUtility->MaxGain());

// Delete current audio sample from beginning of file

iMdaAudioRecorderUtility->SetPosition(TTimeIntervalMicroSeconds(0));

iMdaAudioRecorderUtility->SetAudioDeviceMode(CMdaAudioRecorderUtility::ELocal);

// iMdaAudioRecorderUtility->CropL();

iMdaAudioRecorderUtility->OpenFileL(file);

int nState = iMdaAudioRecorderUtility->State();

iMdaAudioRecorderUtility->RecordL();



Thanks

Hi,

Call OpenFileL() function in your ConstructL() function.

I tried everything ( calling OpenFL from ConstructL ) all gives the same error ("Feature not supported" ) I just don't get it.
It should be very simple.

I have the same error,my code is:
iMdaAudioRecorderUtility->SetAudioDeviceMode( CMdaAudioRecorderUtility::ELocal);
iMdaAudioRecorderUtility->SetVolume( iMdaAudioRecorderUtility->MaxVolume() );

// Set maximum gain for recording
iMdaAudioRecorderUtility->SetGain(iMdaAudioRecorderUtility->MaxGain());
iMdaAudioRecorderUtility->SetPosition(TTimeIntervalMicroSeconds(0));

iMdaAudioRecorderUtility->RecordL();

it does not work,but when I add a line before "iMdaAudioRecorderUtility->RecordL(); ",like this:
// Set maximum gain for recording
iMdaAudioRecorderUtility->SetGain(iMdaAudioRecorderUtility->MaxGain());
iMdaAudioRecorderUtility->SetPosition(TTimeIntervalMicroSeconds(0));

CEikonEnv::Static()->InfoWinL(_L("Press any key and begin..."),_L(""));
iMdaAudioRecorderUtility->RecordL();
it workes well,I really don't know why this happend,can anyone tell me?
