    PCM to AMR & vice versa - Bad audio quality on 6630

    Hi Guys,

    I tried solution given by stenlik and lighthu for descriptors (no file involved)

    Everything works fine on emulator except (as known) loss of PCM 256 bytes on emulator.

    But when i try same app on 6630, quality is bad. To debug the reason i tried 320 buffer size on emulator and i observed on emulator as well quality is bad if the size of the buffer given to CMdaAudioInputStream is kept 320.

    I remember somebody also mentioned similar problem.

    Looking for response from somebody who could able to resolve this issue.

    regards,

    By the way is it possible that quality may improve if we try different rates of AMR?

    Perhaps i will also try that
