Description

"32-bit 16.8 float (type 1 – 32-bit)
This is Cool Edit Pro’s internal format. Floating point values are in the range of +/-32768.0, but larger and
smaller values are valid and not clipped since the floating point exponent is saved as well. The .wav
BitsPerSample field is set to 32 and BlockAlign is set to 4 bytes per channel."
