Hi Julian,
Thank you for this very useful program. I use my tablet, connected to my dac via a 10-foot usb-c to usb-b cable, to play pink noise/tones while measuring sound with a Dayton IMM-6 connected to my Pixel 6 Pro phone. Everything else played through my phone or tablet is streamed via WiiM Pro and that made me wonder if it was possible to add a cast option to the Analyser tab. I searched the discussions for 'cast' and came up empty so there may be little interest in this option. Anyhow, though far from a necessity, it would be a nice feature to have.
