Hi,
I need to calculate the total playing time of the audio files in a
particular folder. These are variously encoded--flac, ogg, and even some
mp3.
Hey Janina,
ecalength from the Ecatools[1] can do some, but mostly fails on ogg. I'm not sure how
accurate it works on MP3s. Mplayer1 tends to get it wrong, but supports all the rest in
MP3 very well. So caution! Length info is easily extracted.
sndfile-info[1] can do anything but MP3.sndinfo[3] also uses libsndfile and comes with
csound. It also lacks MP3 support. Also easily parsable with awk.
A simple check on extensions can help in a shell script to process all but MP3 with the
sndfile based tools. No idea on output format.
[1] http://www.eca.cx/ecasound
(package name: ecasound, perhaps ecatools in addition)
[2] http://www.mega-nerd.com/libsndfile
(package name(s): sndfile-tools, sndfile-programs and/or libsndfile1)
[3] http://www.csounds.com or http://csound.github.io
(package name: csound)
Package names are based on Debian packages.
