Ya, I think I made it pretty confusing. I was pumped as I was writing and ramling on a bit.
I basically applied a test tone to the analogue input of my M-Audio FastTrack Pro USB audio interface and recorded it at 24/96 using Audacity.
The test tone was at -60dB and noise floor was at -80dB (noise floor of the M-Audio interface).
I them applied a negative gain to the recording (-50dB) so that the levels were reduced by 50dB so the test tone went down from -60 (-50) to -110dB and the noise floor went from -80 (-50) to -130dB.
These levels can’t exist in a 16bit file because the absolute minium signal 16 bit can have is -96dB.
Since I saw the test tone at -110 and the noise floor at -130 the playback from the Hub must have been 24bit.
I’m convinced enough that I am now saving my audio (vinyl transfers) at 24/48 to play on the Hub.
