Description
The AudioModule by default uses a 300 Hz cutoff high-pass filter for audio from all decoders. This is intended to filter any DC offset and any sub-audible signalling in the LTR decoders. However, this prevents the end user from disabling the filter to analyze the demodulated audio.
Provide an option to enable/disable audio high-pass filtering for the NBFM and LTR-based protocols.
