Pitch

Can set pitch for the sound like this: min_pitch_multiplier="0.9" max_pitch_multiplier="1.1"

If values are different - random value between min-max is selected. If you need constant pitch - make both values equal.

How to play a sound

Read sound index

int soundIndex = SoundEvent.GetEventIdFromString("YOUR_SOUND_ID");

Several ways to play a sound

UISoundsHelper.PlayUISound("event:/ui/inventory/take_all");

Worked ok:

mission.MakeSound(soundIndex, Vec3.Zero, false, true, -1, -1);

Did not work:

SoundEvent.PlaySound2D(soundIndex);

Works:

SoundEvent eventRef = SoundEvent.CreateEvent(soundIndex, mission.Scene);
eventRef.SetPosition(_mission.MainAgent.Position);
eventRef.Play();

is2D option

Setting is2D to true makes it play at a constant volume throughout the entire scene.

is_2d="true" in XML

Sound in menus

args.MenuContext.SetPanelSound("event:/ui/panels/settlement_village");  // one-time sound on opening
args.MenuContext.SetAmbientSound("event:/map/ambient/node/settlements/2d/village");

Why does not work on wait-type menus?

Sound Events

hunharibo: You don't need the event prefix. Only vanilla sounds use 'event:' to identify sounds in the fmod middleware. Since fmod is a licensed proprietary library, modders cant use that

Possible to play sound (events) with InformationManager.AddQuickInformation(text, 0, null, string SoundEventPath)

You need to null the SoundEvent when you leave the mission.

Same with MultiSelectionInquiryData and in the menus

In GauntletUI: HandleQueryCreated played with SoundEvent.PlaySound2D(soundEventPath);

SoundEvent.PlaySound2D("event:/ui/notification/quest_fail");

soundEventPath looks like:

"event:/ui/notification/levelup"

Some info about events

the event:/ derives from the FMOD event paths that the game uses to play sound events
however when we mod the game’s audio we don’t have access to the FMOD project and their events, so we have to replace entire events with singular oneshots
the event:/ is part of an event path
for example, “event:/Ambience/Rain” would be an event called Rain located in a folder called Ambience

Issues with sound volume using SoundEvent

Windwhistle: My findings so far:

When using SoundEvent to play a custom sound in module_sounds.xml from the sound category "mission_ambient_3d_small" and "mission_ambient_3d_medium", if the attribute is_2d is set to false, the volume of the sound at max volume (close to the sound source) is directly related to the distance at which it was spawned to the player.

So, if you set the position of the SoundEvent FARTHER from the player, it will be FAINTER at MAX volume. If you set the position of the SoundEvent CLOSER to the player, it will be LOUDER at MAX volume.

It draws confusion, as I do not mean that the sound becomes fainter as you travel farther away from it. That's normal. I am not talking about that. There's some videos if you scroll up that depict what I am talking about, because it's pretty hard to describe.

To fix this: I just set is_2d to true instead of false, and the sound plays how I wanted it to play.

Why: I don't know. I'm going to test it out in a regular scene/mission to see if it's my code somehow, or if it's a genuine bug. It might not even be a bug but intentional, but it'd be weird if it were.

EDIT: it also suffers from the same problem in a regular scene. Setting the position repeatedly on tick also does not alleviate the issue. Making the file format .wav also did not help.

Delayed stop to prevent ambient sounds from looping

private async void DelayedStop(SoundEvent eventRef)
{
  await Task.Delay(soundDuration);
  eventRef.Stop();
}

How to get sound duration?

Stop looping example

SoundEvent eventRef = SoundEvent.CreateEvent(SoundEvent.GetEventIdFromString(SoundEffectOnUse), Scene);
eventRef.SetPosition(GameEntity.GetGlobalFrame().origin);
eventRef.Play();
DelayedStop(eventRef); // used to prevent ambient sounds from looping

Short sounds for agents in Mission

agent.MakeVoice(SkinVoiceManager.VoiceType.Grunt, SkinVoiceManager.CombatVoiceNetworkPredictionType.NoPrediction);

SkinVoiceManager.VoiceType examples

Grunt - eeh
Jump - yah
Yell - eyah, hey, yeee
Pain - uh, mhmph
Death - uuuuhmmm
Stun - yyy, aaaa, eeee
Fear - yaaaaah, aaaah
Climb - ?
Focus - (silence?)
Debacle - aaaaaaah, shriek/screech
and many others...

Custom Music

Create your own soundtrack.xml in YOURMOD/music/soundtrack.xml

using System;
using HarmonyLib;
using psai.net;
using TaleWorlds.Engine;
using TaleWorlds.MountAndBlade;
using TaleWorlds.ModuleManager;

namespace Patches
{
    [HarmonyPatch]
    public static class MBMusicManagerPatches
    {
        [HarmonyPrefix]
        [HarmonyPatch(typeof(MBMusicManager), "Initialize")]
        public static void OverrideCreation()
        {
            if (!NativeConfig.DisableSound)
            {
                string corePath = ModuleHelper.GetModuleFullPath("YOURMOD") + "music/soundtrack.xml";
                PsaiCore.Instance.LoadSoundtrackFromProjectFile(corePath);
            }
        }

        // this will only work if you have custom audio? with ID 401. By default comment this out to play default menu music
        [HarmonyPrefix]
        [HarmonyPatch(typeof(MBMusicManager), "ActivateMenuMode")]
        public static bool UseTowMenuMusicId(ref MBMusicManager __instance)
        {
            Random rnd = new Random();
            int index = rnd.Next(401, 401);
            typeof(MBMusicManager).GetProperty("CurrentMode").SetValue(__instance, MusicMode.Menu);
            PsaiCore.Instance.MenuModeEnter(index, 0.5f);
            return false;
        }
    }
}

In your MOD/music/soundtrack.xml you can reference native audio by adding ..\..\..\..\music\PC\ in their <Path>

Original:

<Path>MBII_Campaign_Maintheme_Variation.wav</Path>

After the patch:

<Path>..\..\..\..\music\PC\MBII_Campaign_Maintheme_Variation.wav</Path>

Custom Music in Taverns

By culture:

Sandbox\ModuleData\settlement_tracks.xml

Source here

Find the music
Convert to OGG
In \Mount & Blade II Bannerlord\music\Soundtrack.XML find Maintheme and under it: <TotalLengthInSamples>
Change the number to your sample length using:

or multiply 44305 X {Your song length in seconds}
Backup \Mount & Blade II Bannerlord\music\PC\Maintheme.ogg
Rename your music ogg file to Maintheme.ogg and place it in \Mount & Blade II Bannerlord\music\PC\

Requires patching:

public class CharacterCreationCultureStageView : CharacterCreationStageViewBase

NAudio

Artem:

This is for everyone who tries to add sounds to the game and is annoyed by the game restrictions, like sounds being too short, too quiet, etc.

https://github.com/naudio/NAudio

Install NAudio

RMB on your project:

Example Play Audio method

using NAudio.Wave;

public static async void PlayNAudioSound(string audioFileName, double soundLevel = 1.0, double musicLevel = 1.0, bool soundLevelByNativeMusic = false, bool fadeOutNativeMusic = false)
{

    if (audioFileName.Length == 0) return;

    string _audioLocation;
    AudioFileReader _audioFile;
    WaveOutEvent _outputDevice = _outputDevice = new WaveOutEvent();

    string fullName = Directory.GetParent(Directory.GetParent(Directory.GetParent("YOUR_MODULE").FullName).FullName).FullName;
    _audioLocation = System.IO.Path.Combine(fullName, "Modules\\YOUR_MODULE\\ModuleSounds\\General\\");
    try
    {

        _audioFile = new AudioFileReader(_audioLocation + audioFileName + ".wav");

        // set sound level by native sound or music level
        if (soundLevelByNativeMusic)
        {
            _audioFile.Volume = NativeOptions.GetConfig(NativeOptions.NativeOptionsType.MusicVolume) * (float)musicLevel;

        _audioFile.Volume = _audioFile.Volume * NativeOptions.GetConfig(NativeOptions.NativeOptionsType.MasterVolume);

        _outputDevice.Init(_audioFile);

        if (fadeOutNativeMusic) PsaiCore.Instance.StopMusic(true, 1.5f); // stop native Music with fade-out

        _audioFile.Seek(0L, SeekOrigin.Begin);
        _outputDevice.Play();

        // calculate the duration of the audio
        // Get the total number of samples in the file
        long totalSamples = _audioFile.Length / (_audioFile.WaveFormat.BitsPerSample / 8 * _audioFile.WaveFormat.Channels);
        // Calculate the total duration in milliseconds
        double durationMs = (double)totalSamples / _audioFile.WaveFormat.SampleRate * 1000;


        await Task.Delay((int)durationMs);  // wait till audio stops playing

        if (fadeOutNativeMusic) PsaiCore.Instance.ReturnToLastBasicMood(true); // restore native Music

        // cleanup
        if (_outputDevice != null)
        {
            _outputDevice.Stop();
            _outputDevice.Dispose();
        }

    }
    catch
    {
            // ERROR   ($"ERROR: can't play NAudio sound: {audioFileName}. Missing folders/files? " + _audioLocation);
    }

}

Implementation example: Artem's Assassination Mod

hunharibo: I expanded on the NAudio integration idea a lot in TOR. Made a MixingSampleProvider so you can actually play multiple sound sources at the same time if you wanted to. It only takes 48khz stereo vorbis files though. LINK. Also has rudimentary 3d spatial sound with stereo panning and distance attenuation
