Wav File Source

It reads audio stream from a Microsoft PCM (pulse code modulated) (.wav) file (all versions of GNU Radio) and every other file format that libsndfile supports (GNU Radio 3.9.0.0 and later).

Its output is a float stream.

Unless called otherwise, the values are inside the range of [-1:1].
