Most playback software can be used to edit the metadata. Format conversion software usually also copies the metadata into the appropriate fields.
For MP3 files ID3v1 is the old way of storing metadata inside MP3 files, but it doesn't support unicode so around the world it's not very popular. For example it will not work well even for latin-based languages such as german (they have some non-english characters). ID3v2 is completely different from ID3v1 and pretty much every player these days (software or hardware) supports this.

We're going to use this song to play with, because there are no copying rules associated with it: http://www.openbsd.org/lyrics.html#36
== Audacity ==
On windows the version of Audacity available isn't the newest one (it's a challenge to compile) and because there is no package management a few plugins are not avaiable. But we can still do a few neat things with it in the lab. If you have your own linux box - by all means use that.
=== Part 1 ===
* Go to http://audacity.sourceforge.net/ and download and install the windows version, and install it.
* Download the pond-erosa puff ogg file.
* Open that file in audacity. On windows the menu option is "open", on newer versions in linux it's "import".
* Export the file as wav and as ogg.
* Try to export it as mp3. You may get an error saying that lame is not found. Go back to the audacity page and download and install lame for audacity for windows.
* Export as mp3 as well.
* The windows version can't export as Flac so I will give you a copy on a usb stick of the Flac version.
* Make a screenshot with the folder with all 4 files and audacity with the original open.
Note that you would normally start with an uncompressed file (wav or flac) and use that to creat the compressed files, but we don't have the uncompressed version of this file so we're just going to pretend.
=== Part 2 ===
We're going to blip out some words we don't like in the song.
* Pick a word you don't like (for example "free") and find where it appears in audacity, make a note of the times in a text file. The lyrics are on the website, should make that a little easier.
* Note: you can select a region of the song and play only that.
* Add a new track (mono should do)
* Generate a tone to overlap with the playback of the words you selected earlier. Try not to overlap other parts of the song.
* Zoom out so the whole song is on one screen, and make a screenshot.
* Submit your text file and the screenshot.
== Compression ==
On linux you can compress things with tar cvzf sourcefile dest.tar.gz On windows you'll have to download and install winrar (or another app if you prefer).
