Major apologies brain strain, time of year, age etc. The key issue, is that the coefficients for volume reduction have been chosen (well for SB3, Duet and Transporter, no idea on Squeezeplay stuff) to allow reduction of volume by up to 30 dB, using coefficients that are multiples of 1/256. This means all the top 16 bit values (original sound values) are mapped to new 24 bit values with all values exactly fitting in the 24 bits available. No loss in resolution of 16 bit data just loss in signal to noise ratio. Obviously this only works for original 16 bit data sources.
