Ease Audio Converter Plus is a software which directly decodes one compressed format to WAVE or encodes WAVE to any compressed format.
Ease Audio Converterit can help you to convert audio your files.

It converts the audio files digitally-not through the soundcard-which enables you to make perfect copies of the originals.

You can decode compressed format to WAVE, so you can burn your own CD audio (Assuming you have a CD-R) or use your favorite audio editor. And you can also encode your WAVE files to any compressed format to small your files.
