hi Richard,
could you explain why Samplitude (checked with 6.0 `producer 2496') uses 16-byte headers for 32-bit float .wav files? I mean, is this a violation of the standard? How should we treat such cases?

WAVE 32bit floats is easy ; the wFormatTag field is 3 instead of 1, and the various bitspersample and blockAlign fields have to reflect the 32bit wordsize, as you woudl expect. You should use the WAVEFORMATEX form of the header, 18bytes long (the added 16bit word is zero; it gives the count of any extra bytes in the header, which would indicate a compressed format). 0dBFS value is 1.0; "over-range samples are allowed, and should be clipped by the rendering device".
