Sometimes when I download a video it turns out to have some issues that has raised the audio pitch of the video making it not so enjoyable to watch/hear. So I wonder if there is an ffmpeg command that can modify the pitch of the audio without changing the playback speed or lipsync?
I know some things can be done in this area, for example when I speed up playback of a video in VLC the time runs faster and people move faster but audio is still at normal pitch, frequency-wise. I believe VLC uses ffmpeg too. I have also created a script that can change lip-sync of audio in a video so that YouTube videos with say 500 ms out-of-sync can be corrected to be in sync. This uses ffmpeg. But is it possible to change audio pitch without changing video speed? If so what command should I use? Video should play at normal speed. -- Bo Berglund Developer in Sweden _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
