It is - only useful if you have more than 2 loudspeakers. - - ``[ch1,ch2,...]`` - The delay in ms that should be imposed on each channel (floating point - number between 0 and 1000). - - To calculate the required delay for the different channels, do as follows: - - 1. Measure the distance to the loudspeakers in meters in relation to your - listening position, giving you the distances s1 to s5 (for a 5.1 - system). There is no point in compensating for the subwoofer (you will - not hear the difference anyway). - - 2. Subtract the distances s1 to s5 from the maximum distance, i.e. - ``s[i] = max(s) - s[i]; i = 1...5``. - - 3. Calculate the required delays in ms as ``d[i] = 1000*s[i]/342; i = - 1...5``. - - .. admonition:: Example - - ``mpv --af=delay=[10.5,10.5,0,0,7,0] media.avi`` - Would delay front left and right by 10.5 ms, the two rear channels - and the subwoofer by 0 ms and the center channel by 7 ms. - ``drc[=method:target]`` Applies dynamic range compression. This maximizes the volume by compressing the audio signal's dynamic range. (Formerly called ``volnorm``.) |
