Hello Bluesheep,
There seems to be a bit of confusion here. The two tuners in the RSPduo both run off a common reference clock and so if tuned to the same frequency, both tuners will be phase locked and I/Q streams are time aligned. However, because as things currently stand, the two tuners (to operate simultaneously) have to operate in separate instances of SDRuno, then as the instances cannot be started simultaneously, buffering means that the audio for the two tuners will not be time aligned between the separate instances of SDRuno.
The solution to this will be when we release a version of SDRuno that can process both I/Q streams within a single instance and this will allow us to perform diversity and noise cancellation. This is currently scheduled for release 1.4 of SDRuno which will be the release after 1.3 which is currently in development.
We already have customers who (under Linux) have developed their own noise cancellation software using the RSPduo and our current service based API and so we know that the technology works just fine.
We cannot give a schedule for release 1.4 as there is still a lot of development work on-going for release 1.3 which includes a range of long promised features such as scanning, moving registry settings to a .INI file, piping I/Q audio to VAC etc.
I hope this clears up any confusion.
Sincerely
