Hello I was converting a bunch of youtube videos into 16kHz wav files using ffmpeg
I used the following commands youtube-dl -f best /path/to/youtube/video/ -f 'bestvideo,bestaudio' -o '%(title)s.f%(format_id)s.%(ext)s' ffmpeg -i /path/to/download/m4a/audio -acodec pcm_s16le -ar 16000 -ac test1.wav When I use these youtube videos https://www.youtube.com/watch?v=E1mGPeLqg2g https://www.youtube.com/watch?v=XBFOP_pF7PY I see many blank spots in their spectrograms (see the ones uploaded here https://drive.google.com/file/d/0BzNdoGke8tyRSGgwUUtSTkgxdEE/view?usp=sharing ) Natural speech should not have such artefacts. I am confused why this is happening. Is it because of ffmpeg conversion of m4a audio OR was it somehow fault of the original recording? Thanks. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
