    original sound is 4:18 min, but output sound duration is 4 minutes and it sounds accelerated. How can i fix it ?

    by the way, original sound is

  • FFMPEG change Tone Frequency, keep length (Pitch Audio)

    26 September 2022, by dazzafact

    How can I change the Tone frequency.
This Example only pitches it by keeping the old tone frequency and only decrease the length of File.

    


    For Example, I have a constant 100 Herz tone (as mp3) and I want it to change 90 Herz

    


     ffmpeg -i 100h.mp3 -af atempo=100/90 90h.mp3


    


    This Example doesn't work for me, it sounds the same

    


    inputfile Mp3
    
outputfile Mp3

    


  • Audio along video processing together by opencv

    25 February 2015, by user3397178

    I am going to do some video processing so that I need my audio signal as well. I wanna develop a framework which extracts the frames of an input video file, processes (like tracking an object, etc) and then combines all frames together to have a new video. As I did it by means of Opencv, it is so straightforward. But as I know, OpenCV does not handle the audio signal along with video. The important point which I really have to do is to have a processed video along with sound. I would like to have the original sounds after processing in the new created video.

    I have heard that, I can do Audio processing with ffmpeg and video processing by Opencv, but I don’t have any opinions regarding that. It would be really appreciated if you give me a hint, a general overview or any possibilities for this task. Is is possible to integrate these two libraries (OpenCv, ffmpeg) together and do the mentioned task? If so, how can I do that? (any help, hint or suggestion is appreciated)

    thanks in advance
    Bests,
