Steve, Thanks for the informative post. It turns out that audio mapping is one of my interests, and I am particularly excited about this possibility with the 6000. I currently use a 4in 4out M-audio board connected to an outboard Mackie 1642VLZ mixer to map audio between software and hardware boxes. But in the future a digital mixer may be more appropriate. And with PowerSDR, VAC channels are useful for routing audio signals around. It's not just to get audio from different slices to different destinations, although that is useful and important. It is also for processing applications like voice processors, spectrum analyzers, and recorders. That is where it gets the most use in my shack. In my opinion the audio from each slice should be available on a separate mono channel. New possibilities are coming!

First I'd like to address your question from a "what could be" standpoint since most of what you're talking about hasn't been done yet. The slice receivers today are 24kHz wide and this audio could be sent out of the radio to remote clients, either PCs or whatever. It would require software on the PC to decode the audio, make it look like a soundcard or play it out the speakers, etc. We also plan to have one or more wider bandwidth channels out of the radio. These could be 48-384kHz I/Q data that could be analyzed to look at multiple channels. For remote operation we plan to have audio shipped, likely with a software codec for bandwidth reduction, to a remote device. In the lab, we have brought out the 24kHz slice receivers to a PC and played these out a PC speaker. It would not be that hard to have each one of these go to a separate PC. We might even be willing to make the software available for the remote end that we use today so that someone could build a multi-channel device like you suggest. For your specific application, there might need to be a piece of software that would connect the FLEX-6000 audio to the electronic patching system you mention. If this is something that you or someone else would like to talk about in some more detail, we could have a conversation about it. I agree with you that there are lots of exciting applications for these kinds of capabilities. It will take some enthusiastic technical folks to build them and make them available and we'd like to do what we can to empower those folks where possible.
