Does not support floating point format files

[alhirzel]

When opening a .wav file with floating-point sample encoding, the following error results:

wave.Error: unknown format: 3

This appears to reflect a limitation in the built-in wave library: it does not support floating point format. Is this support desirable for guano-py or outside of its use case?

What hardware or software created this .wav file? Was it a hardware bat detector or bat-specific software?

You are correct, the Python stdlib wave module does not support floating point recordings: python/cpython#60729
