That 48 bit thing could hark back to Protools when it used the Motorola
56k DSP chips:

which are fixed point DPS chips.

According to this:

Protools uses 48 bit fixed point arithmetic (possibly doubled 24 bit
registers of the Moto 56k or possibly custom hardware).

If it is 48 bit fixed point I would think that it is inferior to
Ardour which almost certain uses double floating point which has
a 53 bit significand.
