I'm working on a project which has the requirement to automatically
determine the runtime of audio files in several formats, right now mp3
and aac.
I googled around to see if there might be some existing code,
hopefully ruby code which can determine this, but I'm coming up dry.
Any ideas?
cfp:~/src/ruby > mp3info -p "%S seconds\n" /Users/ahoward/mp3/hot\ chip\ -\ crap\ kraft\ dinner.mp3

I got curious and decided to look at RAA.

mp3info claims to be able to give mp3 length.

Take a look at the metadata gem. It harnesses several libraries to provide
meta-information from a wide variety of formats. Not sure if runtime length
is stored in the file's metadata but it may serve your needs.

I wrote this to determine how much dictation there is to do in my office to see how backed up the typist is. It's a quick and dirty program but it works
#---------------------------------------
#
# Compute time of unfinished dictation
#
#--------------------------------------
# Version 1.1 1/18/07
require 'find'
file_tb = Array.new
Find.find(".\\trdict",".\\Dictations") do |f|
if f =~ /DONE/
Find.prune
elsif f =~ /wav/
fsize = File.stat(f).size
time = fsize.to_f * 0.00157 / 1000.0 #minutes
file_tb.push([f,fsize,time])
elsif f =~ /WMA/
fsize = File.stat(f).size
time = f.size.to_f * 0.008123 / 1000.0
file_tb.push([f,fsize,time])
end
end
totSize = 0
totTime = 0
#file_tb.each {|x| p "#{x[0]} #{x[1]} #{x[2]}"}
file_tb.each {|x| totSize += x[1]; totTime += x[2]}
p "# Files=#{file_tb.size}, File Size=#{totSize/1000000} MB, Total Time=#{totTime} Min"
sleep 10

Where does this mp3info come from? I installed mp3info from
http://ruby-mp3info.rubyforge.org/ following Carlo's lead, but it
doesn't seem to have a command line component.
But looking at an example of the podcast I need to handle, in both mp3
and aac format, neither seems to have any duration related tags.
So I guess I need to figure out if there's any way to compute the duration.
Any ideas anyone?

Except that it doesn't handle the file types I need.

osx? port install mp3info
otherwise: MP3Info

share your knowledge. it's a way to achieve immortality.

I have just yesterday tried a script using mp3info, which worked a treat identifying some music files and giving their length
even though their was no tag data. Hope this helps.
require 'mp3info'
Dir.chdir("C:/Mymusic)
musicdir=Dir.glob("*.mp3")
musicdir.sort
out=""
musicdir.each do |f|
Mp3Info.open(f) do |mp3|
l=mp3.length
mins=l.divmod(60)
if mins[0]==0
ln=mins[1].round.to_s+" secs"
else
ln=mins[0].to_s+ " minutes, "+mins[1].round.to_s+" seconds"
end
fl=mp3.filename
out+= fl + " length: "+ln+"\n\n"
end
end
f= File.open("musicinfo.txt","w")
f.write(out)
f.close

mp3info tries to estimate the running time unless you run it with the -F option,
which tells it to scan the whole file and count frames etc.
I have a command-line version installed in Debian using apt-get, and the same
version installed in Windows. I haven't tried the Mac version yet.

Ara,
Thanks!
We'd found another program called sox as an alternative, but at least
on OSX, it's rather slow, it's really an audio file transcoder and it
seems to be doing quite a bit of work to discover the playing time,
several seconds for a 30 minute MP3.
