  • Creating farms of unique websites

    13 avril 2011, par

  • concat 2 mini audio files and make a loop and add a background music

    11 octobre 2020, par Johny Sharma

    I Need to concatenate 2 small audio files with loop and add background music in a single command.

    



    I am capable to concatenate two audio files with a background music. My above given code is working.

    



    ffmpeg -i 1.mp3 -i 2.mp3 -i background.mp3 
-filter_complex "[0:0][1:0]concat=n=2:v=0:a=1,volume=1dB,aformat=fltp, pan=stereo|c0=c0|c1=c0[a0]; 
[2]volume=0.5dB,aformat=fltp,pan=stereo|c0=c0|c1=c1[a1];[a0][a1]amix=inputs=2:duration=longest,aformat=fltp[a]"
-map "[a]" -strict -2 -y output.mp3


    



    but i want to a make a loop of the concatenated files till the end of the background music. background music is longer than approx 5 times from concatenated files.

    



    If someone can suggest a single command solution.

    



    I know about amovie tag but unfortunately its not possible to use in here because amovie requires file name which is not possible with concatenated files as per my knowledge.

    



    Can anyone help me how can i achieve my goal !

    



    Thanks

    


  • Ducking music using FFmpeg

    24 février, par angel_30

    I want to duck a music audio with a speech audio using FFmpeg (ducking is commonly used to lower background music anytime a person speaks, then raises it when that person finishes speaking). How can I do it with FFmpeg or any other tools (if any) ?

    


    There was an FFmpeg filter called sidechaincompress which merges the two, but it doesn't "duck" them. It takes 2 audio inputs, 1st input to be compressed depending on the signal of 2nd input and later compressed signal to be merged with 2nd input :

    


    ffmpeg -i main.flac -i sidechain.flac -filter_complex "[1:a]asplit=2[sc][mix];[0:a][sc]sidechaincompress[compr];[compr][mix]amerge"
