Uganda Radio Network will only accept .wav and .mp3 files as these are the most commonly-used file formats for digital audio. When a contributor uploads a file, the website recognises its format and automatically converts the file into the alternative to offer stations the choice between the two technologies.
As a rule of thumb, converting a .wav file into a good-quality .mp3 will create a file about one tenth the size, which helps explain some of the popularity of the .mp3 format.
