Subject: Re: [OT] Re: Looking for code to determine length of audio files

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
