Oscar, not to pump the competition, but, both "Rock" and " PSDR" should allow you to make compensations for latency in those cases. You might give them a whirl if you have not done so.

Hi,

as some of you might be aware, some sound cards exihibit the annoying problem of a sample delay on one channel and the digitized data is therefore delivered to SDR software sooner or later than those processed by the other channel which causes big trouble in I/Q mode applications.

Most commom SDR programs such as Winrad, Rocky or PowerSDR have the possibility to delay the sound card sample processing of Left or Right channel by one sample (Winrad even most flexible allowing 1-4 samples delay, but perhaps this is total overkill).

For example my Sounblaster Live24 exhibits such a sample delay problem.
I would like to use it with my Softrock V9 in SDR-Radio, but currently can't make use of it, because of the sample delay doesn't allow proper image rejection.

I wonder if this problem is known and currently in the "To Do" list for SDR-Radio?
