IMO the suggestion to use a different remote-screen technology is a good one too. IIUC the windows Remote Desktop (RDP) routes local (client) audio devices to the remote server, in addition to graphics (server -> client) and keyboard/mouse (client -> server). It makes sense - one typically wants...

The hardware works the same way on linux and windows. But the hardware configuration can be different. My 2 cents - there is some gain USB control in your USB capture device which gets set differently in windows and linux. IIUC REW itself operates this control, if the checkbox "control input...

Since you are using plughw:X device (i.e. using the alsa plug plugin), any format is always available. My 2 cents your device is enabled in pulseaudio/pipewire and used by that sound server, thus blocking out the direct alsa access by java in REW. Always disable a device in PW/PA if you want to...

That device is described as 12 x 18 audio interface. If it really supports 12 input and 18 output channels and not fewer, then the wasapi-excl plugin would not check for 18 output channels...

You can use newer JDK, look at e.g. https://www.avnirvana.com/threads/rew-linux-installation.6711/ .

I just tested beta 100 and runs OK on my amd64 with java 21: Do you have correct path to the launcher jar (e.g. REW_DIR/.install4j/launcherd9d2fef3.jar in my case)? Your error looks like java cannot find the main REW class which is in that jar: pavel@precision:~$ jar tvf...

Unfortunately the Wayland support in java has still a long way to go https://openjdk.org/projects/wakefield/ https://wiki.openjdk.org/display/wakefield/Work+breakdown

Switch your desktop to X11 and check if it helps. Just google out the method (it should be at login screen).

Maybe your system switched from X11 to Wayland? What does echo "$XDG_SESSION_TYPE" say ?

IMHO USB is way more compatible with current and future host devices than firewire. Technically both interfaces are just transferring data anyway, good audio devices have conversion master clocks on their sides. Well engineered (especially multichannel) USB2 highspeed devices use the packet...

Yes, if the ADC distortion component to the combined distortion is negligible, compensating (i.e. adding distortions of opposite phase) on the DAC side only works OK. The problem is when the ADC distortion is not negligible, while being also compensated on the DAC/generator side . Then the...

Separating DAC and ADC distortions from the combined loopback measurement is by principle not trivial. The standard way is using a steep notch filter on the ADC side which suppresses the DAC distortions before the AD conversion. REW supports measuring the notch filter params and compensating its...

@redmountain : how is clock master determined in your "firewire stream"?

@redmountain : what REW buffer size do you use?

But that's not related to some differential mode, but simply averaging the vector distortions of the two channels (each a bit different) improves the resultant distortion, statistically.
