Recording both channels of RSPduo in dual tuner mode

Post by js9013 » Wed Jul 10, 2019 6:26 pm

Hello,

Is it possible to record the IQ OUT data from both channels of an RSPduo at the same time? I can't get the scheduler to start recording at the same time (something about not being able to create a WAV output file). However, if I wait a second or so later, I can get both channels to record while the duo is in master/slave mode. I am just not sure that it is indeed sampling each channel separately concurrently.

Thank you!

Start 2 instances of SDRuno (one master and one slave) and you can start the recorder in both instances (assuming you are writing to 2 different WAV files)

Thanks for the quick reply! I guess my question is - can I schedule both the master and slave to start recording at the same time? When I try to do this, I get an error saying that it could not open a WAV file for output.

Nothing intentionally designed to prevent this - maybe there is something in the underlying windows audio system that is blocking the creation of the 2nd wav file for a period of time?

Do you have any recommendations on troubleshooting this? It would be very convenient to have them scheduled to run at the same time.

I don't know how you will get 2 applications to do the same thing at the same time.

This may well be a good idea for a plugin for the SDRuno plugin API that will come in 1.4
