Re: Thetis 2.8.11 Released!

Voicemeeter ASIO drivers used with a Presonus Studio 192 Mobile, 128 bit Word-locked to a 48 kHz Bodnar GPSDO clocking source. Same source used for the 10 MHz external reference. Paul, W9AC Hi Paul, Just curious, why do you use Voicemeeter between Thetis and your Studio 192 Mobile? 73, Bryan

Re: What does "Use RX2" do?

Dear friends, In Setup/Audio/VAC1, Direct I/Q box, what does "Use RX2" do? Michael In OpenPowerSDR it used to select the RX2 IQ stream, instead of the RX1 IQ stream, for output through VAC1. In Thetis I don't believe the ChannelMaster was ever hooked up to this Setup control. It appears t...

I understand why VoiceMeeter is needed, i.e. to patch PowerSDR & MAP65 together. But why ASIO4ALL?

Hi Enzo, The solution file in "Thetis\Project Files\Source" should load the PortAudio project along with all the other projects automatically within VS2019. The dependencies are wrong I think. Just remember that ChannelMaster depends on WDSP and Thetis depends on ChannelMaster. 73, Bryan W...

Re: MON sounds different LSB to USB...??

Yeah, you're not wrong, most people don't even notice it though. The MON system is a bit crude, in that what you are listening to is the complex baseband (I/Q) signal being sent out to the DUC in the radio hardware. So it's not real audio per se. Somewhere in the bowels of this forum is an erudite e...

Re: VAC doesn't show me a WASAPI option

Hi Mark, WASAPI is trapped out in the code and not shown in the VAC1 ComboBox on purpose because the latency is so bad (~30ms) in shared mode. PortAudio doesn't work correctly with WASAPI in exclusive mode (which is very fast, but badly distorted). The PortAudio guys are currently trying to address ...
