Hi. Thanks fore all the suggestions. I've experimented with a lot of
combinations over the years, and you can hear the difference. I guess what I'm
asking, is how low can you get away with and still have acceptable voice
quality. I guess that's an impossible question to answer since not everyone's
hearing is the same. A golden eared audio file will hear things someone else
won't even notice. If you want to try an interesting experiment and you have
goldwave and good headphones with a flat response from 20 to 20 kHz, try
testing your hearing to see just how far up the spectrum you can hear a sine
wave. select a kHz tone and turn the volume up just until you barely hear it.
Never never go any louder than that as you increase frequency. if you don't
hear a tone after lets say 16 kHz, it doesn't necessarily mean its not there,
it just means your hearing probably rolls off at that frequency. Again. Don't
turn up the volume since you don't want to damage your hearing. Keep it just at
the point you can hear a 3 kHz sign wave. I pick that frequency because most
peoples hearing is OK there, so what you perceive to be a low volume level at
that frequency is probably accurate. This test is far from precise but it
gives a good idea of someone's hearing range. You may not hear as high as you
think you can. Anyway, thanks for all the answers. I'll continue to experiment.
The recordings I'm making are just voice recordings of tutorials on how to use
an amateur radio from a blind perspective that I'm putting on line. I'm also
voice tagging names of albums on my thumb drive for my NLS player to be put in
audio+podcasts. Thanks again. Joe.
