Not all .wav files are uncompressed, or even the same format if not
compressed.
You are correct. The file uses ADPCM compression, I believe, so it is
not CD quality. It uses a bit depth of 4 bits, which is de-compressed
when playing to 16 bit.
It's really just a practical question, is the MP3 audio quality as
good as the (compressed) source WAV.
I would keep the oriiginal WAV file, but web browsers can't play this
particular type of WAV file.
