How PCM16 data is arranged in 8 bit CMMFBuffer ?

[Md. Kayesh]

hi,
PCM16 is a 16 bit data. We get this data stored in a 8 bit CMMFBuffer. My question is how it is arranged. I guess it is arranged in 2 bytes and follow little-endian. Am I right or wrong ? Please help me.

Since no one answered in the past 1+ days, it might be easier to check. Besides endianness, you may also want to check if the data is signed or unsigned.
While I do not know the answer for your question, in case of a simple CMdaAudioOutputStream 16 bit PCM is stored as signed little-endian.

Yes, you are right wizard_hu_. PCM16 is stored as signed little-endian.
I am facing one problem while recording in PCM16. I always get 4096 byte at a time. Can I fix it in my own way so that i get at my desired size in BufferToBeEmptied() ?

The 4096 is some standard thing: http://www.developer.nokia.com/Commu...dioInputStream
For MMF magic, there is some TMMFCapabilities::iBufferSize which you can try setting.
