What does fuzz, hiss and hum in the IVC settings do?
-
Hello, I’m trying to remove the radio voice effect from IVC but I’m not sure what to tweak, any help please?
-
I’ve been wondering as well- haven’t had a chance to fiddle with it aside from adjusting a few of those settings slightly upward. Haven’t noticed a difference tho.

They’re basically DSP effects designed to try and make the otherwise pristine VoIP audio sound more like what you’d hear over real radio equipment in the jet. The fuzz acts kind of like an overdrive pedal for a guitar – think heavy metal chords (overdrive) versus acoustic guitar strummed. The hiss adds noise – I think I used pink noise if memory serves – there’s almost always some hiss from this kind of radio equipment. Lastly the hum is a 400Hz tone that simulates picking up interference from all the 28V 400Hz power that drives a lot of the gadgets in the cockpit – think like hearing alternator whine over the stereo in a car with poorly shielded/grounded audio equipment.
All of these are tunable to taste up to and including turning them all off. While some of the effects, like range roll off and LoS attenuation and ground clutter are dynamic varying with the situation of your jet, these particular three effects are fixed extent – set them once in the ini file or with the command line and they stay constant strength throughout your flight.

thanks I appreciate the guitar examples !

well in case you’re curious I’ll be going with something like this. Fuzz was already at 0, and also I don’t know if its a 0 and 1 setting or something like hum and hiss that goes to -18, the tech guide PDF doesnt mention it, so idk about that one.

Pekins - I think “fuzz” is described in the 4.35 technical manual, on page 18-246, but under the heading “Radio distortion”. It says the range is 0 -15. Hope this helps.

Right so 0 is the minimal value then, yeah I tested using the settings I posted above and the radio filter is still heavily present.
Edit: I think I found it might be nofx = 0
-
Sadly nofx = 0 made no difference
-
I don’t believe nofx has a value, it’s a switch.
Just uncomment the line so it reads
–nofx

So this is all documented in the BMS Technical Manual if you want to look it up long hand.
The nofx parameter is an on/off switch so adding it to the command line (by including “–nofx”) invocation for the client will apply it. In the ini file, a value of zero disables nofx and a value of 1 in the file enables it.
The purpose of nofx is to deliver clean sound instead of radio-like sound. There are still range-roll-off and line-of-sight effects so volume levels can be attenuated or cut off (respectively) depending on the relative position of players trying to talk to each other over IVC if you are both in the 3D world. So…
If you want to remove all DSP effects to get at clear audio then you want nofx enabled. So either add it to the command line or change the value from zero to one in the ini file for that line (which based on the file image pasted above means: remove the “#” from the start of the nofx line and then change the “0” to a “1” and see if that works for what you want).

Sorry but that’s not what the manual says, if if that is what it means
"Sound effects: /N or –-nofx
If present this switch will cause all sound effects processing to do with signal strength and interference to be omitted. This results in clearer sound reception although volume attenuation at extreme ranges is still present. In testing, it was noted that in some cases of mixed language speakers, heavy accents are already enough challenge to communications without the additional difficulties in hearing due to audio degradation. This switch can help if you need to set up a connection that is relatively clear in the 3D world but still sounds like radio transmission.
Example: “<yourinstallpath>:\FalconBMS\Bin\x86\ivc\IVC Client.exe” /N"
There’s no indication of a 0 or 1 flag, just the explicit existence of - - nofx

No, I believe that is what the docs say…but one has to read the whole section. I’m not sure how to make it much clearer in the docs. Did you notice that post #9 above talks about both the command line and ini file way to use this nofx thing?? The zero/one only applies to the ini file. The section you are quoting talks about the command line. The subsequent section of the docs describes how the ini file works and how it relates to the command line equivalents.
In short though: the ini file treatment for equivalents to command line arguments that are just switches is zero for “like there’s no command line option present of this type” and one means “like the command line did include the switch for this type”.

Ah, yes, reading is good. Thanks for the clarification.
I must have read that section a dozen times, but never noticed the inference - I guess that’s the difference between theory and practice.

Alright noted, I use the .ini only, dont really know how command lines work, I’ll first try with “nofx = 1” if it doesnt make any difference I’ll try with “nofx” only
