Print bitrate of each audio file

find . -print0 | xargs -0 -I{} ffmpeg -i "{}" 2>&1 | grep "kb\/s\|Input"
This useful command will help to detect bitrate of each audio file in folder where it will run for.
Sample Output
Input #0, ogg, from './Omega/01. Track 1.opus':
  Duration: 00:03:40.97, start: 0.000000, bitrate: 140 kb/s
Input #0, ogg, from './Omega/01. Track 10.opus':
  Duration: 00:05:38.18, start: 0.000000, bitrate: 127 kb/s
Input #0, ogg, from './Omega/01. Track 11.opus':
  Duration: 00:04:10.09, start: 0.000000, bitrate: 125 kb/s
Input #0, ogg, from './Omega/01. Track 12.opus':
  Duration: 00:05:41.90, start: 0.000000, bitrate: 128 kb/s

  • With the -vn switch we make our intentions clear and ask FFmpeg not to bother itself with the video. Next we specify the audio codec copy, which tells FFmpeg to use the same codec to encode the audio, which it uses to decode it. To keep things simple, we'll just keep the sampling and bitrate values the same.

  • ffmpeg -i = input file name -s = set frame size, qcif=176x144 -vcodec = force video codec -r = frame-rate [default = 25] -b = bit-rate [200 kb/s] -acodec = force audio codec -ab = audio bitrate in bits/s [64k] -ac = no. of audio channels [1] -ar = audio sampling frequency [44100 Hz] optional: -sameq = use same video quality as source (implies VBR) -f = force format -y = overwrite output files

  • Batch Convert MP3 Bitrate to xxxkbps, all the new files will be placed in a folder called "save". Please replace xxx with the desired bitrate. WARNING!!! This will erase any tag information; this is where Picard or EasyTAG will come in handy. Show Sample Output


    -1
    mkdir save && for f in *.mp3; do lame -b xxx "$f" ./save/"${f%.mp3}.mp3"; done

  • This commands saves the output in the audio directory. The portion ${file/%avi/mp3} uses bash string replacement to replace the avi to mp3 within the ${file} variable.
