not sure what you mean by support for other sample rates. RTs are recorded at 16 bit 44.1 sample rate but that's just the way things are. once you export to wav and move to a DAW you have the choice of sample rates etc. admittedly the BIAB exported tracks are confined to the original quality but if you find that a limitation you can always buy the audiophile version of BIAB. same sample rates etc but the audio is not compressed.
