I have a WAV audio file.
How can I determine if this is the compressed or uncompressed WAV format?
How can I determine what the sample rate/bit rate is?

WAV is an uncompressed audio format!

In Windows, you can see the file information in Windows Explorer when you activate the Details pane: Organize -> Layout -> Details paneAudio File Info

That's not strictly true, the .WAV format can be used with compression.  Most often though it is associated with LPCM encoding which is almost identical  to the PCM format used for CD Audio (CDs contain PCM format audio which is effectively WAV without its RIFF header)
