+Should run completly fine on a pi 5, right now with the preemp, on a pi 3b, its 20%

+# Recommendations
+use a lpf, for example swh-plugins's lowpass_iir, for example:
+
+```
+pactl load-module module-null-sink sink_name=FM_Audio rate=48000 # this goes to fm95
+pactl load-module module-ladspa-sink sink_name=FM_Audio_lpf sink_master=FM_Audio plugin=lowpass_iir_1891 label=lowpass_iir control=15000,6 rate=48000 # use 4 poles minimum
+pactl load-module module-loopback source=radio_audio.monitor sink=FM_Audio_lpf rate=48000 # from the apps to the filter
+```
