  • Is there a way to speed up audio processing (amix and adelay) in FFMPEG ?

    22 mars 2018, par Nadir

    I’m using, in android application, many ffmpeg amix and adelay filter commands over very small mp3 files (not longer than 3 seconds).
    Unfortunately each adelay or amix command takes between 2 and 4 seconds to execute, which is a lot considering that I should run the same operation for a lot of files.
    Here are two example of commands I’m running :

    amix :

    [-i, input1.mp3, -i, input2.mp3, -filter_complex, amix=inputs=2:duration=longest:dropout_transition=0,dynaudnorm=f=100[aout], -map, [aout], -ac, 2, -c:a, libmp3lame, -q:a, 4, output.mp3]

    adelay :

    [-i, input3.mp3, -filter_complex, [0:a]adelay=1|1, -c:a, libmp3lame, output1.mp3]

    I know in video there is an option (-preset ultrafast) to make the execution faster, is there a way to do the same for audio ?
