Sound Configuration FilesOverviewThis document describes the format of sound configuration files, which determine the sounds to use for each aircraft, or other simulated object
Currently, there is no 'easy' method for implementing audio within Dovetail’s Flight Sim World (referred to as FSW), such as through the use of a front end 'blueprint editor' like found in a commercial engine such as Unreal Engine 4. Instead FSW relies on configuration files (.cfg) that 'direct' the game to where the audio files are located as well as defining the parameters for their playback, such as where they can be heard, their pitch, their volume, etc. It is advised you install a program such as Notepad++ or Visual Studio Community Edition so that you can create and edit these sound.cfg files, which are essentially text files. Below is a screenshot of the sound config file for the PA-18 SuperCub from FSW open in Notepad++ to act as an example for what a typical sound config file will look like. Table of ContentsCurrently on FSW, audio audio files have very stringent formatting requirements. This is due to the technical limitations of the FSW engine; file size considerations; and from various compatibility changes. As it stands: - All aircraft, ambient, mission VO/SFX, weather and UI sounds MUST be set to have a sample rate of 44.1 kHz and a bit depth of 16 bits.
- ATC voices MUST be set to 8 kHz and 8 bits.
Additionally, all sounds on a particular in-game “channel” (such as aircraft sounds or UI sounds) need to have the same number of channels (mono/stereo). For aircraft sounds we use mono, whilst UI and weather sounds are all stereo.
If something is incorrectly formatted and you are running the game through Steam on the test branch then asserts will trigger to tell you something is wrong.
Naming Conventions
When naming our audio files internally, we tend to stick to the following format, the sections of this you choose to use will largely differ from one aircraft to the next:
'COMPANY'_FSW_Aircraft_'AircraftName'_'exterior (x)/interior (blank)' 'sound' 'front/rear' 'number' 'left/right'
Here are some examples of this from some of our core bundled aircraft:
DTG_FSW_Aircraft_PiperSupercub_xRPMf01
DTG_FSW_Aircraft_DA42_RPM01Left
Looking at the first example given above, working from left to right we're able to see that: this sound was produced internally at DTG, that it's for use in Flight Sim World, it's a sound for the PA-18 SuperCub aircraft, the use of 'x' in front of the sound name denotes that this is an exterior sound (if there was no 'x' present we would know that it's a sound that should be heard in internal views), we can see that because it's named 'RPM' that it's an engine sound, the 'f' tells us that it should be heard when the player camera is in front of the engine ('r' would tell us it should be heard when the player camera is behind the engine), and lastly the '01' states that this is the first loop in a list of sounds.
Of course you're welcome to follow whatever naming convention/s are most easily understandable to you, the most important thing is to make sure you're able to just read the audio file's name and be able to understand exactly what the sound is. The only bits from the guide given above that we highly recommend you use are denoting whether a sound is exterior ('x') or interior (leave blank) and whether a sound should be heard in a front ('f') or rear ('r') arc around the engine.
Audio Directories The are several directories in FSW where audio files are stored: the "core audio folder", "pack audio folders" and "mission audio folders". The core audio folder, as the name suggests, is centrally located and can be referenced by anything bundled with the core product or by any DLC. Pack and mission audio folders need to be kept specific to each DLC pack and thus should only be referenced by that pack specifically. Core Audio Folder
Provided you have installed FSW in the directory Steam allocates by default, the core audio folder is found here: C:\Program Files (x86)\Steam\steamapps\common\DFS\sound The core audio folder is where sounds are stored that can be referenced by multiple DLC packs, such as default mission music files, a myriad of default aircraft sounds, crash, splash and ground rolling sounds, as well as a few "special" sound effects that can be used in missions, if you so wish! Pack Audio Folders
Pack audio folders are those that are specific to certain DLC packs. They are found in the SimObjects folder and technically apply to everything in there (Airplanes, Animals, Boats, Characters, Ground Vehicles, Misc), though we just focus on the aircraft and leave the rest with their defaults. For now we'll look at the "Airplanes" folder, and as an example we shall look at the PA-18 SuperCub: C:\Program Files (x86)\Steam\steamapps\common\DFS\SimObjects\Airplanes\Piper_PA18
Within this folder are two sound folders, one simply named "sound" and one named "soundai". Both work in exactly the same way, with the only differences being that one is for the player aircraft and the other is for all AI aircraft in the game-world. Generally the AI folder should have less sounds in it for two reasons: - Technical limitations in the engine mean that AI aircraft cannot use startup, shutdown, starter, wind, ground or miscellaneous sounds. Just engine sounds.
- The AI version of an aircraft may simply reference files in the "sound" folder, since both the player and AI versions will be provided as part of the same DLC pack.
What is important to remember is that all the sounds in both folders are heard from the player's perspective, so all internal sounds in the "sound" folder are for those heard by the player in the internal camera views (same applies to external sounds when in external views), but it also means that internal sounds in the AI folder are for when the player is in an internal camera view of their own aircraft (same applies to external AI sounds).
Once again, config files in a pack audio folder should only ever reference sound files in the pack it is in or in the core audio folder, NEVER anything from another pack. This is because not all users will have all the DLC and so each piece of DLC needs to be self-contained.
Mission Audio Folders
Mission audio folders are specific to each mission and are for mainly storing mission specific voice over as well as the occasional sound effect, such as an aircraft being loaded with bags or engines 'popping'. You may wish to also include music files in these folders, however there is now also a core folder that missions can reference that contains generic music that can be referenced. As an example we'll take a look at a mission folder from the Epic Approaches Mission Pack DLC:
C:\Program Files (x86)\Steam\steamapps\common\DFS\DLC\630910\Missions\Approaches\Big Bear Approach\Big Bear Approach - Level 1\Sound
Audio specific configs are not needed as part of missions. Instead, the mission writers have their own files that they will reference both your voice over and sound effect audio files from.
The Sound System The sound.cfg file is located in an aircraft’s Sound folder, and defines the sounds to use for that aircraft (such as the sound of the engine at various speeds, the sound of the landing gear going down, and so on). This file also specifies attributes for each sound that determine exactly how the sound is played. Many aircraft sounds in are composed of multiple .wav files (called a sound list) that are linked to one another, processed in sequence, and then played as a group. These sounds are updated by the simulator’s sound engine every time the screen refreshes (once every frame). Whilst these sounds don't need to be listed in a particular order, it will make your life easier if you group certain sound lists together (combustion, prop, startup, shutdown, starter, etc). As you read this section, you should look at actual sound.cfg files to become more familiar with the structure and syntax of them. They can be found in the Sound subfolders of the aircraft containers, and viewed using any text editor. To hear any particular component of a sound in its pure form (unaffected by the attributes in the sound.cfg file), just play the .wav file referenced in the sound.cfg (.wav files are located in either the Sound folder in an aircraft’scontainer, or in the core audio folder). Notes: - For clarity, the naming convention used for our core bundled Flight Sim World aircraft engine sounds was to put an “x” at the beginning of all external sound (heard in external spot and tower views) headers, and to number consecutivesound headers (e.g., [SHUTDOWN], [SHUTDOWN.1]). The specific headernames used does not matter, as long as they are consistent in the[SOUND_ENGINE] section and across link parameters. Additionally, theorder of the sections within the sound.cfg file does not matter, nordoes the order of the parameters within a section.
Defining the Flight Sim and Sound Engine
In the first section of the config file there are two sections. The first, titles "[FLTSIM]" is the section where are define the product code ("FSIM") and whether or not there is an alias. An alias is used to basically say "this aircraft will use the sounds of this other aircraft" if they will be completely identical. A hypothetical example of this could be for an aircraft that we wish to use completely the same sounds and settings as the PA-28 Cherokee. In this case we would write "alias=Piper_PA28\sound", this tells the Flight Sim engine where to look for the intended sound.cfg file. It is thus very important that what you write in the 'alias=' section matches exactly the containing folder names of the sound.cfg you wish to point to.
The second section is where you define the sound lists for the engines, props and startup/shutdown/starter sounds as well as the number of engines. Looking at an example of the sound config file from the PA-28 Cherokee (shown below) we can see that it has a single engine and that for this single engine there are single sound-lists for each of the various groups of sounds: combustion (engine loops), starter (startup), combustion_start (engine ignition), shutdown, prop (propeller), non-combustion (engine mechanical sounds).
To act as a comparison, have a look at the sound config file for the core bundled Diamond DA42 (screenshot below), this shows how things should be set up for aircraft that have two engines.
The [SOUND_ENGINE] section focuses specifically on the engine sounds for the aircraft and is nothing needs to be added to this for covering the ground, wind or miscellaneous sounds (these will be discussed in following sections). Additionally, each engine specified in the sound config file will then have its source point assigned automatically by finding the corresponding number in the aircraft config file. Note that in the sound config file the engines will be named from '1' to 'N', whereas in the aircraft config file they will be named from '0' to 'N-1'. So it ends up looking somewhat like the following:
| Sound Config File | Aircraft Config File | 1
| 0 | | 2 | 1 | | 3 | 2 | | 4 | 3 | | ... and so on | |
Following is a description of each section of a sound.cfg file.
General Sections [fltsim]Property | Description | Examples | | product_code | This parameter should always be set to: FSIM | Aircreation_582SL( product_code=FSIM ) | | alias | A sound folder path, relative to the root folder. If an alias is entered, do not enter any more information into the sound configuration file - all the sounds from the aliased folder will be used. | b747_400( alias=B737_800\sound )
DH_Dash8_100( alias=beech_king_air_350\sound )
MD_83( alias=B737_400\sound )
PA28_180( alias=c172\sound ) |
[sound_engine]These parameters concern the engine sounds of an aircraft. They specifythe number of engines the aircraft has, and the sound lists thesimulation should use to create the aircraft’s engine sounds. Eachsound list is referenced by the header of the first sound in the list(additional sounds are linked to in sequence from that first sound).The individual sounds in a list are defined in their own sectionswithin the sound.cfg file (see the Specific engine sound parameters section below). The engine numbers reference the engine positions in the[generalenginedata] section of the aircraft configuration file, exceptthat in this sound file engines are numbered 1 to N, whereas in theaircraft configuration file they are numbered from 0 to N-1. This meansthat eng1_combusion, for example, references engine.0 in the aircraftconfiguration file, eng2_combustion references engine.1, and so on. Theaircraft configuration file gives the position of the engine relativeto the datum reference position for the aircraft, and this positionwill be the source of the engine noise.

| Aircreation_582SL( flags=125218 ) | | minimum_speed | Specifies the minimum speed (in KTAS) used by the _volume and _rate parameters. | Aircreation_582SL( minimum_speed=3 ) | | maximum_speed | Specifies the speed (in KTAS) above which the sound has constant volume and pitch. Specified in KTAS units. | Aircreation_582SL( maximum_speed=55 )
C208B( maximum_speed=25 ) | | minimum_volume | Specifies the lowest possible volume--if the sound dropsbelow the minimum volume specified, it will not be heard. (Volume isspecified in 1/100dB units, with a value of 10,000 being the maximumpossible volume.). | B737_800( minimum_volume=10000 )
Bombardier_CRJ_700( minimum_volume=6500 )
DG808S( minimum_volume=8000 ) | | maximum_volume | Specifies the highest possible volume--the sound neverexceeds the volume specified. (Volume is specified in 1/100dB units,with a value of 10,000 being the maximum possible volume.). | Bombardier_CRJ_700( maximum_volume=10000 )
Mooney_Bravo( maximum_volume=9300 ) | | minimum_rate | Specifies the minimum rate at which the sound is played. If theaircrafts speed is between minimum_speed and maximum_speed, theplayback rate is interpolated between the minimum_rate and maximum_ratevalues. | Aircreation_582SL( minimum_rate=0.80 ) | | maximum_rate | Specifies the maximum rate at which the sound is played. If theaircrafts speed is between minimum_speed and maximum_speed, theplayback rate is interpolated between the minimum_rate and maximum_ratevalues. | Aircreation_582SL( maximum_rate=1.60 )
Bombardier_CRJ_700( maximum_rate=1.0 )
C208B( maximum_rate=0.95 ) | | panning | Determines where the sound is placed in the stereo field:
0 = center
-10,000 = full left
10,000 = full right
| Bell206B( panning=-10000 ) | | initial_volume | Specifies the volume at which the sound starts. (Volume isspecified in 1/100dB units, with a value of 10,000 being the maximumpossible volume.). | Bell206B( initial_volume=10000 ) | | viewpoint | Determines when the sound is audible, one of:
1 = internal cockpit views
2 = external spot and tower views | C208B( viewpoint=1 ) | | link | References the next sound in a sound list (by section heading name).Some ground sounds are made up of several .wav files, and each .wavfile has its own section in the .cfg file. | Aircreation_582SL( link=GROUND_ROLL2 )

These sound sections take the following parameters: Property | Description | Examples | | filename | SSpecifies the name of the .wav file to play. The .wav extension should not be specified. The Sound folder in the specific aircraft container is searched first, and then, if the file isn't found, the root Sound folder is searched. Note that[CRASH_SOUND] and [SPLASH_SOUND] filename parameters have commaseparated filenames and the sound played will be randomly chosen fromthe listed files.
Some miscellaneous sound sections consist of no more than the filename entry. | Aircreation_582SL( filename=cncrash1,cncrash2 )
