Reason for the awful turret spin-up noise.
« on: December 09, 2009, 05:59:01 am »
Today, cron discovered and posted the cause of the awful turret spin-up sound

Quote from: irc
16:26:09 «@unnamedplayer» cron: up to help with some bug finding about the sounds?
16:26:21 « cron» sure
16:26:45 «@unnamedplayer» ok I suspect it's entirely about the encoding of the files that throws openal off
16:27:15 «@unnamedplayer» can you make/get some test files we can use to check at each level (bitrate,etc.) ?
16:27:44 « cron» mhm
16:27:44 «@unnamedplayer» I'll be home in lik 15 mins to test with my openal laptop
16:28:01 «@unnamedplayer» lets test whole range and see what works/doesn't work and what sounds like shit on openal
16:28:32 «@unnamedplayer» if it's just encoding problem we will have a fix in time for gpp2 :)
16:29:10 «@unnamedplayer» probably work with turret sound since that's so obvious
16:29:22 « cron» i'm fairly certain ii'm 98% sure the issue is with 8 bit sound
16:29:57 « cron» let me test the ret spinup sound at 16 bit
16:30:00 «@unnamedplayer» yeah, lets make that 100% and then we can get ioq3 guys to fullly investigate while we have a fix for trem in the mean time :)

17:05:36 «@Khalsa» Nice big game on US1 atm
17:06:20 « cron» i found the problem :o
17:06:27 «@Khalsa» oh?
17:06:33 « cron» it's not 8bit sound, it's stereo sound :P
17:06:40 «@Khalsa» really?
17:06:42 « cron» sounds have to be mono
17:06:59 «@Khalsa» makes sense actually
17:07:02 « cron» mhm
17:07:12 « cron» openal provides any stereo effect
17:07:30 « cron» openal/sdl
17:07:38 «@Khalsa» so in essence you hear the turret sound from every direction in stereo
17:07:41 «@Paradox» wow
17:07:46 « cron» yup
17:07:51 «@Paradox» that is something i never would have expected
17:07:56 «@Paradox» but it makes perfect sense
17:08:04 «@Khalsa» Good job cron \o/


Anyway, for those of you who are afraid of reading IRC, here is the basics of what happened.
  • Cron found out that most sounds are mono, but turret sound was stereo
  • OpenAL only cares about mono sounds, as it does the mixing of channels (makes sense right)
  • 2 channel sound=2 times the mixing=insane ear shattering poop sounds

As of now, it has become a requirement on the map repo for maps to use mono sounds only. I am working on adding this to the validator.

I disagree with this. Music sounds better with stereo sound, if anyone were to use it.

The use of music on maps is highly discouraged.

Its not a requirement, but it WILL warn you about it if you do have stereo.

Mostly because people don't want to listen to looped tracks of crappy music.

Ambiet sounds and the like can be very nice, but actual music can be distracting and annoying to people who just want to play without having to listen to someones song.

I assumed that a song=background music. I see what you mean now though. I'd probably go insane if I had to listen to a particular song every time a certain map was played.

I have music disabled, I prefer to hear footsteps etc.  Also I can play my own music if I want it.

That's cheating.  Obviously, playing your own music will mean you have an unfair advantage over the other players.  

Don't cheat and hack!

The fact that there can be quiet times in this game is one of its best features imo.

Music unapproved by the devs should result in permabans from all major servers.

most of the time, disabling music and ambient sounds will give you a nice fps boost anyways. its not that crucial of an issue :/.
