RM-Noise FM-Repeaters

It would be interesting to offer RM Noise for FM repeaters, but the AI should also include TX audio equalization and automatic RMS leveling. There are certainly some open-source implementations that could achieve this. This way, RM Noise could be used in the transmission path and always be optimally modulated.
Additionally, the audio could be processed to such a high quality that it would be seamlessly compatible with a Speex or Codec2 vocoder. Furthermore, voice fingerprinting could be implemented in the future to automatically block undesirable folks from abusing the repeaters.

fnords: Interesting suggestions.

I'm considering an API for the filtering engine, so in the future [audio bandwidth issues aside] the outbound FM filtering/equalization could be done by any 3'rd party.

Voice fingerprinting isn't something that *I* plan to pursue, but this capability would be great if false positives were extremely rare.


Please forgive the late reply ..hurricane.. Thank you.
