Free converter audio online official site: easy audio converter online download pick finally freeware audio converter express Monkey's Audio (APE) is a lossless audio file type. Unlike traditional methods such as MP3, OGG, or WMA that permanently discard quality to save space, APE does not discard data during the process of encoding but still saves a lot of space. And you can always decompress your Monkey's Audio files back to the exact, original files. A fly in the ointment is that we often failed to play APE files on our media player (like iTunes, Winamp, WMP etc) or portable devices (like iPod, iPhone, Android etc). The file is being converted from a WAV file to whatever compressed format is chosen.
