    I have converted my brother's wedding to disc in mpg video file.
    The audio (in mono) is poor with white noise and low volume.

    I have split the mpg file
    1. use TMPGenc into .m2v video and .mp2 audio files.
    2. also used DVD2Avi into .avi video and .mp2 audio files.

    I have these audio editing tools: CoolEdit Pro 2.0, NGWave Audio Editor 3.3; Audio Edit Magic 8.6.

    I am only able to use Audio Edit Magic to read in the .mp2 audio file and save it into .mp3 files for other audio editing programs.

    I am unable to improve the sound quality by increase the audio amplitude and low the white noise.

    Your advice is much appreciated.

    In detail, this is what I did:

    Use TMPGEnc to demux the mpg file into video .m2v & audio .mp2 files.
    Use Audio Edit Magic to open the audio .mp2 file, then save as .wav (Windows PCM)
    Use CoolEdit 2 to open the .wav file,
    1. use Effect, Noise Reduction, Hiss Reduction, standard Hiss Redutcion, (get noise floor, 14 drag points)
    2. use Effect, Amplitude, Normalize to 100%

    Then, use IfoEdit to multiplex the video + audio (with -11ms) delay.

    The sound is louder, but sounds like taking into a can, and still have sync problem.

    Your advise is much appreciated.
