Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/wirtz/OpenAudio_ArduinoLibrary/commits/commit/7a57dfc7b80dc66568a931361a1021ca919fbd8a/examples/SpectralDenoise
You should set ROOT_URL correctly, otherwise the web may not work correctly.
Add Spectral NR example. Example switches between
'passthrough' and 'Spectral NR' processing every 10
seconds to allow comparison.
Input is via I2S and USB. Output is on I2S/headphones
