Greetings
I specially send very low signal to audio input.
Dream can work excelent with very low level audio signals -100db PSD

But no visible shifted PSD level.

One can increase Y range in shifted PSD level.
I want test minimal pure radio signal level enough for software decoding.
Its need for long distances DX and receive 1296Khz BBC and other MW stations
on 80m delta loop

Your screenshots are amazing, and you have put together an even more amazing set of hardware.
I have best results with an input level where the Input PSD has the top of the DRM signal at the -60dB line.
In the Dream main dialog, there is also an input level meter showing a transition between red and green
at about -12 or -15 dB (see screenshot attached). With the signal at that transition, the input PSD is
usually at the level I mentioned earlier, and Dream performs best for me.
