  • command line audio equalizer ffmpeg sox

    5 novembre 2016, par user1320370

    I need to add equalizer effect on some flac files :

    f=4043, 1.65q, g=9.5; f=7024, 1.09q, g=3.7; f=9254, 0.94q, g=-2.5

    I was tried ffmpeg :

    ffmpeg -i solovoce_compress.flac -af equalizer=f=4043:width_type=q:w=1.65:g=9.5, equalizer=f=7024:width_type=q:w=1.09:g=3.7,equalizer=f=9254:width_type=q:w=0.94:g=-2.5 solovoce_equalizzato.flac

    but the result is much different then what I expect, this values was calculated by izotope ozone (professional audio editor software) and tested.

    I used the equivalent with sox and the result is some.

    A this point I like to try ffmpeg ’anequalizer’ filter that show the graph so I can ’see’ the difference, but I the documentation to show the graph is not clear and I was not found nothing about on web.

    Someone can please send me an example of ’anequalizer’ with plot enabled ?

  • FFMPEG copying Windows Media Audio 9.2

    19 avril 2016, par David GC

    I want to top and tail a wma file with a codec Windows Media Audio 9.2. I know Windows Media Audio 9 Professional encoding is not supported. But I just need to top and tail this audio file.

    I only get an audio file output with codec Windows Media Audio 8.

    ffmpeg -i .\1_encoding.wmv -acodec copy -preset ultrafast .\prueba1.wma

    Is it possible to get an output with Windows Media Audio 9.2 ?
