1. we can get Amplitude of voice from raw pcm data.
2. alsa or oss could output raw pcm data.

    do like this:
    recordCard = ms_snd_card_manager_get_default_capture_card(ms_snd_card_manager_get());
    msReader = ms_snd_card_create_reader(recordCard);

    Then raw pcm data could be found in msReader output pin.

Hi,
       Given a sampling rate, is it possible to get the amplitiude of the voice, in each sample in mediastreamer2?
If yes, where to look for it?
