Greetings:
One thing that occurs after listening to Repeaterphone users for quite a
while is that their TX audio is often muffled compared to those using
radios, even with good microphone placement and technique. This is less
apparent when using a radio-less node, or even sometimes a personal node
via RF.
Experimenting with various things over the years, I found that using a
flat source as an input to Allstarlink isn't really the greatest way to
go about things, and applying just a few DB of gain in certain
frequencies helps tremendously to get your audio out of the mud,
especially on RF.
Just as an example, I have a setup that currently boosts the frequencies
around 2500 Hz by 3Db given a flat, wide source.
Since Repeaterphone is already using an EQ as basically a gain slider,
as iOS doesn't allow changing of microphone gain since the iPhone 6S and
the original iPhone SE, I propose adding an option to add a fixed,
non-changeable boost somewhere in the mids between 2.5 and 3k to
increase intelligibility. Make it work both with and without iOS
processing enabled, and turn it on by default.
Since I am advocating for this feature, if desired, I would be glad to
help find an optimal sweet spot given the way iOS processing works, but
I think this would be a huge benefit
