Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The "copy" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename). </p> Sun, 24 May 2009 14:32:00 -0500 Golly Trip comment 39444 at http://www.townx.org http://www.townx.org/blog/elliot/nice-ruby-audio-format-transformer-tag-transferrer <p>I have quite a few ogg files, as well as a few mp3s. Occasionally I like to change formats around so I can play oggs on my mp3 player, or give them to friends and family. I have a few batch scripts lying around which do this using ogg2mp3, toolame etc., but they lose the ogg tags and I usually end up with mp3s without tags.</p> <p>I thought things could be better, so I went in search of a tool to help. I found a Ruby script called <a href="http://badcomputer.org/unix/code/sneetchalizer/">The Sneetchalizer</a>, which is great. To get it working I had to install <a href="http://rubyforge.org/projects/ruby-mp3info/">ruby-mp3info</a> (using gem) and download <a href="http://rubyforge.org/projects/ruby-ogginfo/">ruby-ogginfo</a>. The latter isn't a gem, so you have to make sure you include it in Ruby's load path (see the example below). Also, rather than install it, I just pulled the sneetchalizer file out of the tarball, added a .rb to the end of it, and ran it directly using Ruby.</p> <p>Sneetchalizer uses a whole bunch of Linux command line tools and Ruby libraries to do its work, but providing you've got them installed (probably you just need oggenc, oggdec and lame or toolame), it works a charm. It supports a whole load of audio formats and options, so had no problem with my ogg to mp3 challenge.</p> <p>Here's an example of the command line I used to translate some ogg files in one directory into mp3s in another one:</p> <pre> ruby -I ~/Desktop ~/Desktop/sneetchalizer.rb --out=mp3 --in=ogg -r --sanitize \ -D /home/ell/no_backup/music/for_chloe_mp3s /home/ell/no_backup/music/for_chloe </pre> <p>Notice the -I option passed to Ruby, which makes any Ruby files in the stated path (~/Desktop in my case) available on the load path. I also like the fact that you can tell it to sanitize tags (<tt>--sanitize</tt>); and work recursively (<tt>-r</tt>).</p> http://www.townx.org/blog/elliot/nice-ruby-audio-format-transformer-tag-transferrer#comments tech Fri, 14 Dec 2007 17:37:56 -0600 elliot 692 at http://www.townx.org
