Answer 1

with ffprobe

ffprobe your_file.mp3 2>&1 | grep "Duration"

The output looks like this:

Duration: 00:44:33.50, start: 0.011995, bitrate: 128 kb/

Answer 2

sox --info -D file             --> duration in seconds
sox --info -d file             --> duration in HH:mm:ss.ss
sox --info file                --> metadata 

Answer 3

ffmpeg -i <audiofile> 2>&1 | grep Duration

Answer 4

Another soxi based answer including the file names and duration in hours, minutes and seconds format.

$for f in *amr; do printf "$f "; soxi -d $f; done

DGT20161216.amr 00:22:04.62
DGT20170108.amr 00:28:22.80
DGT20170117.amr 00:20:05.18

Answer 5

If you are interested in finding total duration of wav files in a directory using soxi you can use this:

soxi -D input_dir/*.wav | python -c "import sys;print(sum(float(l) for l in sys.stdin))

change input_dir according to your input directory. If you want to find max/min duration between all wav files feel free to change sum to max or min.

Answer 6

on OSX

Print the length of each audio file in the current dir:

afinfo * | awk '/estimated duration/ { print $3 }'

Include the filepath:

afinfo * | awk '/File:/ { song=$2 } /estimated duration/ { print song, $3 }'
