I have an audio file which has the following specifications. Codec: MPEG AAC Audio (mp4a) Channels: Stereo Sample rate: 44100 Hz Bitrate: 253 kbps
It has both leading and trailing silence. I want to remove the silences AND keep the quality intact. So far I've tried ffmpeg -i 1.m4a -af silenceremove=1:0.5:0:1:0.5:0 2.m4a This is supposed to remove both the leading and trailing silences. But for some reason it doesn't remove the trailing silence. There is a similar thread on this mailing list that has the same problem. Also, it reduces the bitrate to 128kbps. This I could fix by adding the -ab 253k and making the command: ffmpeg -i 1.m4a -af silenceremove=1:0.5:0:1:0.5:0 *-ab 253k* 3.m4a Now the problem is that the trailing silence isn't removed and when I want to process a batch of files I can't use the same bitrate (like 253kbps ) for every file. Any help will be appreciated. Thanks. -- View this message in context: http://ffmpeg-users.933282.n4.nabble.com/Silence-Removal-tp4671207.html Sent from the FFmpeg-users mailing list archive at Nabble.com. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
