4.11.4 - High Pass Filter
For maximum voice intelligibility within broadcasts, we can take a cue from AT&T corporation, which long ago did a great deal of research and determined that the frequency range of 300 Hz to 3000 Hz (3 KHz) was the "sweet spot" for voice. If you set ⇔ Hpf = 300, and then set the maximum demodulator bandwidth to 3 KHz, this will provide an excellent setup for listening to AM and SAM voice broadcasts. I find opening up as far as 4 KHz increases detail and intelligibility, if interference is not present.
When recalling memories, if you want the memory recall action to set the high pass filter state and frequency, →Left-click .
