  • Completely remove high frequencies from wav file with ffmpeg

    21 septembre 2021, par Melvin Bender

    For my speech recognition project, I'd like to completely cut off frequencies above 5000Hz on my wav files using ffmpeg.
I understand there is a lowpass filter for reducing frequencies above a certain value :

    


    ffmpeg -i original.wav -af "lowpass=f=5000" lowpass.wav


    


    However when I check the spectogram, it seems like frequencies above 5000 have been reduced, not completely cut off

    


    Voice sample with 5000Hz filter

    


    How can I completely cut off frequencies with ffmpeg ? Any other software is also fine.

    


  • I want to place a heart transition I made between 2 videos with 2 blank png images with alpha , with a 4 sec transition in mkv format with overlap

    14 juillet 2022, par Christopher

    I want to place a heart transition I made that has 2 blank png images with alpha channel, that has a 4 sec heart transition that is in mkv format. I want to overlap the last image of the 1st video, with the transition video for 2 seconds, and overlap the first image of the 2nd video for 2 seconds. This would allow a heart transition, between 2 baby animals, between the clips that make up the videos. I have conceived a way to automate the assembly of over 1800 clips into videos, and this is a part of it. Sorry about the absence of clarity in my question, I hope this makes it clear, what I am trying to accomplish.
