Audio::File::Wav::Tag(3)

NOTE The t/test.wav file does contain metadata ('tags') for 'Music', 'BWAV' and 'Soundminer', but these are not standard.
 Audio::Wav will throw warnings when processing this file
   because it does not understand the non-standard metadata blocks.

 If Audio::Wav is modified to parse these blocks in the future,
   I will add support here.
