  1. Hi there

    I have a multichannel w64 file and would like to boost the LFE channel by +6dB. This is what I have so far:

    RaWavSource("C:\audio.w64", 1).AmplifyDB(+6.0,4)
    SoundOut()

    However my output seems to be louder overall instead of just channel 4. Could it be that channel 4 is not the LFE channel or am I using the function arguments incorrectly?

    Thanks would appreciate any help.

  2. You are using it incorrectly.
    AmplifyDB(clip, float amount [, float amount ]...)
    http://avisynth.nl/index.php/Amplify

    So probably something like:
    Code:
    AmplifyDB(0.0, 0.0, 0.0, 6.0, 0.0)
    (Assuming LFE is the 4th channel in your file.)
