I´m working with a Nokia 6630
I recorded data to a descriptor, that contains the PCM - data, now i want to convert this data to AMR - format.
I read a lot in the forums how this can be done, and i´m stuck on the following problem:
I like to use CMdaAudioConvertUtility to convert that data, but the data is only the raw-data, and the utility needs the source-file-information such as samplingrate, bits per sample, and so on...
I read that i have to attach the 'RIFF....WAVEfmt....data' header at the beginning of the descriptor, so that the converter knows what kind of source he has to do with.
Could anybody please tell me how i can attach this header...
Thanks in advance,
