Net-Remote on SDRSharp baseband Wave file #7

Hello,
It works really fine, i realised a little scanner with it, it also listen to the decoding application to change frequencies.
I try now to record a baseband wave file on SDRSharp an scan the wave file, but i have an error message
{"Result":"Error","Type":"Source error","Message":"Not tunable"}
Is it possible to use your application on a wave file ?
I think the error is that you also pilot the SDR receiver and there is not here, also just a command to set frequency only on the baseband file if it is possible, not tune the receiver, it will work.
Cheers and thanks for this application
