    voice manipulation with Java?

    Hi!

    Is there some way to access/alter the voice data stream with, for instance, J2ME, during conversation?

    Sincerely,
    Tom

    Hi,

    In theory it could be done by using the APIs in javax.microedition.media package:
    - if you would have a Player that plays the voice
    - you would use RecordControl/OutputStream to grab the audio into application
    - you would use another Player to play out the modified audio data.

    In practice you can't since
    - there are no Players for voice stream on the phone i.e. you can't access the voice from the phone conversation.
    - real time signal processing would require too much processing power anyway. Not to mention that you would probably need floats to do the processing.
