    Unhappy Get samples directly from device?

    Hello,

    I am recording audio on Nokia 6131, using the default format amr. I used this code to capture audio:
    player = Manager.createPlayer("capture://audio?encoding=amr");

    But, when I tryed to capture audio in pcm or wav format, it throws NullPointerException. Therefore, I used System.getProperty("audio.encodings") to get supported audio encodings. But I found that amr is the only one supported on the Nokia 6131.

    I need to find a way to get the uncompressed data. Is there any way to get the data read from device directly before the compression to amr? In fact I just need a byte array to work on it.

    I thought that I can try a converter from amr to wav, but the application will be different according to the mobile type. It will be better if I can get raw data.

    Thanks in advance.

    Regards,
    H.M.

    Afaik, it's not possible to get out recorded data in any other format than the ones supported by the JVM implementation itself, so, in any other format than the ones returned by System.getProperty("audio.encodings").
