  • Converting stereo file to mono but preserving peak and RMS loudness

    14 juin 2020, par user319249

    I am converting stereo audio files to mono using ffmpeg.

    



    ffmpeg -i $1 -ac 1 -ab 192k mono_$1


    



    However, after conversion, the RMS and peak loudness levels are not the same.

    



    Tests-iMac:auditions test$ ./rms.sh mono_test.mp3 
 mean_volume: -20.1 dB
 max_volume: -0.2 dB
 Peak level dB: -0.150201
 RMS level dB: -20.138039
 RMS peak dB: -10.650649
 RMS trough dB: -94.923318
 Flat factor: 0.000000
 Peak count: 2.000000
 Bit depth: 32/32
 Number of samples: 5800320
 Number of NaNs: 0.000000
 Number of Infs: 0.000000
 Number of denormals: 0.000000
Tests-iMac:auditions test$ ./rms.sh test.mp3 
 mean_volume: -22.9 dB
 max_volume: -2.9 dB
 Peak level dB: -2.896314
 RMS level dB: -22.883812
 RMS peak dB: -13.397327
 RMS trough dB: -95.943631
 Flat factor: 0.000000
 Peak count: 2.000000
 Bit depth: 32/32
 Number of samples: 5800320
 Number of NaNs: 0.000000
 Number of Infs: 0.000000
 Number of denormals: 0.000000


    



    The first ouput is the mono file which is technically louder than the stereo file, listed second. How can I preserve the peak and RMS values while also converting to mono ? I have no issue scripting in order to obtain the stereo loudness values to pass to the mono conversion process.

    



    Thanks !

    


  • Filter complex with split source and multiple overlays : Can my code be simplified ?

    29 juin 2024, par Patrick Hennessey

    I've created a complex split filter that splits a single 1372 x 1372 input source into multiple uniquely shaped and cropped slices (s1, s2, etc), and overlays them on a padded background plate into a single output. It also applies a 20fps target framerate on the last overlay step.

    


    It works exactly how I want, but I'm wondering if this code is inefficient or redundant in any way :

    


    ffmpeg -i test.mp4 -filter_complex "[0:v]split=5[s1][s2][s3][s4][s5];
[s1]scale=377:377,crop=360:360:2:2,pad=1920:1080:1560:720[bg];
[s2]crop=1372:1068:0:0[s2];[bg][s2]overlay=0:0[bg];
[s3]crop=460:308:0:1064[s3];[bg][s3]overlay=1372:0[bg];
[s4]crop=460:308:456:1064[s4];[bg][s4]overlay=1372:308[bg];
[s5]crop=460:308:912:1064[s5];[bg][s5]overlay=1372:616,fps=20" output.mp4


    


    Is there a more elegant way to achieve the same result ?
