Most portable audio players can play music encoded in the MP3 audio format, but some consumers also have music in Ogg Vorbis, FLAC, MPC, or even WMA files. How do you change from one format to another when you need to? Here are some of the best audio conversion tools available in Linux.
One of the simplest and most elegant ways to convert audio files is by using the audio-convert script. It makes use of Zenity to display GUI messages and windows, but does the rest of its work from the command line.
When you type audio-convert filename, you are presented with a GUI message asking you to choose the output type for the resulting file. You then specify whether you want to pass the existing metadata tags to the newly created file or would rather input them manually. In the latter case, the script inserts the band name and album title for all the tracks after you enter them once. You have four audio quality choices when converting to MP3: medium (160Kbps), standard (220Kbps), extreme (264Kbps), and insane (320Kbps).
