[ecasound] int to float or float to int conversion

Hello,

How does ecasound convert 16-bit ints to floats? It does not seem to
be a simple divide by 38768, since a file with a range of -32768 to
+32767 seems to map perfectly to -1.0 to +1.0 after conversion. This
is not the case when libsndfile is invoked to open the file -- there
it looks like a division by 38768, leading to a range -1.0 to
+0.999969

I'm also curious about the opposite conversion from float to int.

I assume that the conversion methods are the same for 24-bit integers,
but with different multipliers/divisors etc.

Thanks,

Matt
