Vehicle sounds are distorted, some double up and stutter and some sound digitized
Closed, ResolvedPublic

Description

After a recent patch to the dev build vehicles and air craft have had a strange audio glitch.

The helicopters have a strange stuttering, and overlapping of the blade sounds when they start up and persist until you shut the heli down.

The land vehicles (Ifrit, Hunter) have a strange digitized / 8 bit effect.. The motors don't sound like motors. It quite literally sounds like an old dial up modem trying to connect to the internet.. you hear a couple distinct tones that fluctuate.. Like a modem .. not like a motor..

ATV's are also affected. they have a very distinct oscillation not very noticable in "Q" speed however, "W","E" make it clear.

I have uninstalled the game and reinstalled it because I honestly thought it was my PC.. Its not.. It is the Dev build. {F19885} {F19886}

Steps To Reproduce

Go into the editor. Place a playable vehicle, Land or air..

if in a heli.. when you start it up you will hear the start up sequence, and then the overlapping "woosh" and stuttering of the main rotor blades..

If in a land vehicle, simply drive around and you will hear a old dial-up modem instead of the motor...

The distortion occurred for me after last Monday's dev update, maybe it's got something to do with "FIX: APOLimeiter effect for sounds". Just a wild uneducated guess.

Would be interesting if you could post a short sound clip of this. :)

I uploaded two sound clips:
The anomaly is noticeable when the Ifrit accelerates and when the MH-9 starts up. Or is this a desired effect?

By gripe is the sudden appearance of the clipping “blade flap” sound far to early/prominently in the start sequence in 1st person, when really, the main rotor blades are hardly turning either in RL or in the game.

Also blade flap is more prominent outside when past the tip of the rotor as that is always the fastest moving part of a blade and is far less prevalent inside when it’s happening.

Some MD500D/E inside and outside start-ups (same engines etc and airframe as the MH/AH-6 AKA MH/AH-9)
MD500E inside up to full rpm’s:

edit added “mh9_startup_shutdown.zip” (in game “blade flap”) though I chopped the shutdown bit off the file to get it under the file size limit and forgot to remove the “shutdown from the file name/.zip doh!

Our samples sound pretty much alike and to me it's pretty obvious what's amiss. The swelling and subsiding sound gives me a headache.

The sound clip of the Ifrit posted is from the inside of the vehicle.. the sound anomaly is much more noticeable when outside the vehicle. And the MH-9 sound clip perfectly displays the issue... Thanks for posting those guys!!

Actually, the Ifrit was also recorded while in 3rd person, you can hear me enter but I immediately switch view. Just before the engine starts you can hear the grasshoppers. :)

But I understand that this is quite subjective and also depends a lot on the hardware and periphery used.

It seems the latest DEV build fixed this issue (for me). Can somebody confirm?

Mass closing ancient tickets with no activity for > 12 months; assume fixed or too trivial.

If this issue is still relevant in current dev build, please re-post.
