Hi Wolf, LF,

I'm greatly looking forward to this new SL version! Please tell us when it is finished! This would allow me to run the grabbers much more flexible and use a single PC in the shack on the roof, with reduced CPU load.

Hello Peter,

At the moment multiple running instances of SL don't "talk to each other" about the sample rate, even if they use the same audio device for input. In future versions, it will be possible to have the first instance running as 'master', providing a resampled(!) audio stream for all other instances. Those 'slave'-instances don't connect directly to the soundcard, but to the first running instance. I am not sure about how to connect the instances yet (via shared memory, or -even better- via TCP/IP so the slaves could run on physically different PCs if necessary).
All the best,
  Wolf .

I was wondering the following:

I have here 4x Spectrum Lab task running at one PC to serve my SUB9KHz grabber page at
I use that Sampling Rate detector in all 4 Spectrum Lab tasks.
Is that OK, or need I only one Sampling Rate detector that callibrates the other 3 tasks to ?
(one master - 3 clients without that SR cal active)
