WAV files sound better than MP3

摘要

Why did you choose to save the audio files in the "Touch-Screen Digital Audio Recorder" now being presented as ".wav" files rather than what I would have thought was the more commonly used ",mp3" format? Is the unit's firmware upgradeable, as needed and if so, does the possibility exist to upgrade it to perhaps handle either ".wav", ".mp3" or both, as user options when configuring the unit or does the CODEC unit only come with ".wav" capability?
