In 32-bit float, the range of +1 to -1 is used to represent values below 0 dB. 32-bit float is able to represent numbers much greater than 0 dB.
"32-bit signed" is another way to represent numbers with 32 binary digits.
@Venn Isn't 32bit overkill? I didn't think human ears could tell the difference between 32bit and 24bit.
32 bit floating is a 24 bit recording with 8 extra bits for volume.
It provides additional headroom. If a recording is peaking badly you can bring it down and restore the headroom minus distortion.
@Venn Oh, that's neat!
