Help Tweak Audio

[webstar22]

Hey,

I am running https://github.com/szpajder/RTLSDR-Airband on my Pi3 at
http://5.2.67.244/milair.m3u

I was wondering if someone can help me tweak the audio settings.
On my scanners it's clear as a bell but on the Pi3 feed there is static.

Is there any of these I can tweak?

devices:
({
type = "rtlsdr";
index = 0;
# serial = "00000384";
gain = 25.0;
# correction = 0;
mode = "scan";
# sample_rate = 2.56;
# buffers = 10;
