    javame: is it possible to disable AGC / VAD when recording using the microphone?

    Hi,

    We are developing an application which takes audio from the microphone and does some analysis. We found during the analysis, that AGC is implemented on the microphone subsystem. Also I have heard that VAD is used.

    1. Are there any other post processing done on the audio(PCM) before it is delivered to the application?
    2. Is it possible for the application to disable the AGC and VAD post processing? Is it possible in JavaME or using some proprietary API, such as Nokia/Samsung?

    Thanks for your help!

    JavaME does not have such low-level access to the audio stream.
    If you are working on Symbian/S60 devices, you could check if Qt or Symbian C++ has such capability.
