Ruby-mp3info 0.5


#1

ruby-mp3info gives you access to low level informations on mp3 files
(bitrate, length, samplerate, etc…). It can read, write, remove id3v1
and
id3v2 tags. It is written in pure ruby.

This new version add the ability to read, write and delete tag2. I
would like to thanks Chris and all others contributors.

Get tar, zip and gems at http://ruby-mp3info.rubyforge.org/

example:

Mp3Info.open(“myfile.mp3”) do |mp3|
puts mp3.bitrate
puts mp3.length #length in seconds
#etc

puts mp3.tag.title
puts mp3.tag.artist
puts mp3.tag.album
puts mp3.tag.tracknum

puts mp3.tag2.TIT2
mp3.tag2.TIT2 = “my title”
end #tag is written at close()
