Today we’ll be talking about the Preload Audio Data option in Unity’s Audio Import Settings and why understanding this small but critical checkbox is important for your game.

So many options… How does Unity choose which audio is loaded to a scene?

Editor’s Note: Compression Formats, Load Type and the Preload Audio Data/Load in Background settings go hand in hand. We recommend reading our blog posts on all three in the following order for a complete overview:

Blog 1: Compression Formats

Blog 2: Load Types

Blog 3: Preload Audio (this post)

Blog 4: Load in Background (coming soon)

This blog post has been made as a supplement to our video tutorial on this same topic.

 

Testing Testing

We’ve imported 10 sound effects, 10 dialogue, and 2 music files into a Unity project. They’re all marked with Preload Audio Data to simulate a larger game. There are also two different scenes to simulate loading and unloading audio in a normal scene transition.

Let’s start with the first scene. We have a GameObject here with an AudioSource that has an AudioClip.

We hope this looks familiar.

This is already a so-called reference and this audio file will be loaded when the scene is loaded. I turned off Play on Awake for this to make sure that the audio is not played. Let’s build this and confirm with the profiler.

Our AudioClip is loaded and ready for action.

Perfect. Even though the AudioClip is not played at all, it is loaded because it has been referenced.

Note that this music file, which has “Streaming” selected as its Load Type, is only 311 bytes in the memory, unlike the 200-ish kilobytes from the last tutorial. That will change if we actually play the sound file.

Let’s now add two scripts we’ve prepared for another GameObject.

These two scripts do nothing but define a public AudioClip variable and a public AudioClip array. Let’s add an AudioClip to that and profile this.

Voilá. We have the second audio clip loaded.

For the sake of this demonstration, I will add another two AudioClips to the array and check the profiler once again.

As you might have guessed, without Preload Audio Data selected, Unity will not load the AudioClip until it is called, even though it is referenced in the scene. We’ll be going more in-depth on this in our next tutorial.

So, a reference is as simple as that. As long as you have a reference of any kind to an AudioClip, be it directly in the AudioSource, as a variable in a script, or even in a ScriptableObject, it will be loaded when the scene is loaded if you have checked Preload Audio Data.

Scene Transitions

Now: what happens if we change to another scene? Will the audio data we loaded in this scene be automatically unloaded?

Let’s go to the second scene. We’ll keep one AudioClip constant across both scenes but change the rest. Now we can build and profile this once again.

And then we’ll transition to the next scene.

We see here that all but one of our AudioClips from the first scene are already unloaded from the memory, leaving only the one that is used again in the second scene.

The unloading process took place as the scene was changed; this is a normal routine that Unity does in the background called GarbageCollection.

var audioImporter = assetImporter as AudioImporter;
var serializedObject = new UnityEditor.SerializedObject(audioImporter);
var normalize = serializedObject.FindProperty("m_Normalize");
normalize.boolValue = false;

serializedObject.ApplyModifiedProperties();

audioImporter.SaveAndReimport();
UnityEditor.EditorUtility.SetDirty(audioImporter);
UnityEditor.AssetDatabase.Refresh();

모바일 게임을 제작하다 보면, PC-에디터에서는 잘 나오던 게임 사운드가 핸드폰에서는 밀려 나오는 경우를 종종 겪을 수 있다.

이런 상황을 해결하기 위한 설정값을 기록해 둔다.

프로젝트 세팅

Edit > Project Settings > Audio에서 DSP Buffer Size를 Best latency로 설정
- Best Performance : 성능이 우선 되어 출력 시 지연이 발생할 수 있음
- Best latency : 지연이 발생하지 않는 것을 우선시하여 출력 품질이 저하될 수 있음

리소스 타입별 세팅

배경음 1
- Force To Mono : 언 체크(퀄리티에 따라 가변)
- Load In Background : 체크
- Load Type : Streaming
- Preload Audio Data : 언 체크
- Compression Format : Vobis (100%)

배경음 2
- Force To Mono : 언 체크(퀄리티에 따라 가변)
- Load In Background : 체크
- Load Type : Compressed In Memory
- Preload Audio Data : 언 체크
- Compression Format : Vobis (70%)

효과음 : 작은 크기의 빈번한 출력 
- Force To Mono : 체크
- Load In Background : 언 체크
- Load Type : Decompress On Load
- Preload Audio Data : 체크
- Compression Format :  PCM

긴 효과음(보이스) : 중간 크기의 빈번한 출력
- Force To Mono : 체크
- Load In Background : 언 체크
- Load Type : Compressed In Memory
- Preload Audio Data : 체크
- Compression Format :  ADPCM

작은 크기의 가끔 발생하는 Sound
- Force To Mono : 체크
- Load In Background : 언 체크
- Load Type : Compressed In Memory
- Preload Audio Data : 언 체크
- Compression Format :  ADPCM

중간 크기의 가끔 발생하는 Sound
- Force To Mono : 체크
- Load In Background : 언체크
- Load Type : Compressed In Memory
- Preload Audio Data : 언 체크
- Compression Format :  Vobis (70%)

개별 리소스 세팅 정보

Force To Mono(모노 강제조정)
- 스테레오를 모노로 강제 조정
- 모바일이고 최적화를 중시할 경우 설정(체크) 함

Load In Background(지연된 로딩)
- 체크 시 출력 타이밍을 엄격히 지키지 않고, 느긋하게 백그라운드에서 로드
- 따라서 배경음악일 경우 사용 FX 사운드의 경우 체크 해제


Load Type
- Decompress On Load
　실행과 동시에 압축을 해제
　작은 사이즈의 FX 사운드에 유용
　많은 메모리 점유 CPU는 적게 사용

- Compressed In Memory
　메모리에 압축 상태로 저장, 실행 시 압축을 해제하여 재생
　약간의 성능상 오버헤드를 발생시킴
　보이스 사운드 등에 사용

- Streaming
　저장소에 위치한 오디오를 실시간으로 읽어냄.
　보통 배경음악에서 사용


Preload Audio Data
- 씬이 로딩될 때 씬에서 사용하는 모든 오디오 클립을 미리 로드
- 언체크시 플레이시 로드 하기에 랙 발생 됨


Compression Format
- PCM
　최고품질 / 용량 큼 / 작은 파일 크기에 적합 / FX 사운드
　Load Type은 Decompress On Load로 하자
　즉시 재생해야 하는 매우 짧은 효과음

- ADPCM
　중간 품질 / 용량 중간
　PCM대비 3.5배의 압축비, 노이즈가 포함됨
　총격 소리와 같이 무압축에 가까운 품질 까지는 필요없지만,
　지연시간 없이 자주 반복 재생 되야 하는 경우 적절

- Vobis
　최저품질 / 용량 적음 / 배경음에 적합
　압축률 설정이 가능(보통 70%로 설정)
　지연 재생 되어도 무방한 일반적인 배경음

[빌드 에러]

Firebase 10.6.0이 업데이트 돼서 다시 한 번 iOS 빌드를 시도해 봤는데 여전히 에러가 난다.

그래도 다시 이리저리 검색해보다보니 해결했다는 글이 아래와 같이 있다.

Fixed this error with changing the version in "GoogleSignIn.podspec.json" file.

Firebase/Auth (= 10.4.0) was resolved to 10.4.0, which depends on
FirebaseAuth (~> 10.4.0) was resolved to 10.4.0, which depends on
GTMSessionFetcher/Core (< 4.0, >= 2.1)

GoogleSignIn (~> **5.0.2**) was resolved to **5.0.2**, which depends on
  GTMSessionFetcher/Core (~> **1.1**)
I found the file in {user}.cocoapods/repos/cocoapods/Specs and then just search for "GoogleSignIn.podspec.json".
Find the folder with the same version with the error, in my case 5.0.2.
And then change its dependencies with the version 7.0.0 or something that works with the other packages.
In my project the solution was this;

 "dependencies": {
    "AppAuth": [
      "~> 1.5"
    ],
    "GTMAppAuth": [
      ">= 1.3",
      "< 3.0"
    ],
    "GTMSessionFetcher/Core": [
      ">= 1.1",
      "< 4.0"
    ]
After that I exited Xcode, deintagrated pods, cleaned cache and installed it again.
Everything works fine now.

글을 보면 아래와 같은 내용이 있다.

에러도 나와 거의 같아서 확인해보니 GoogleSignIn 버전이 현재 6.0.2여서 GTMSessionFetcher/Core (~> 1.1)를 지원하는데,

설치한 FirebaseAuth 10.6.0은 GTMSessionFetcher/Core (< 4.0, >= 2.1)을 사용하고 있어서

GTMSessionFetcher/Core 버전이 서로 호환이 안되는 것 같다.

위 링크의 내용대로

GoogleSignIn 버전을 7.0.0(2023-03-27 기준 최신) 버전으로 변경하고 빌드를 다시해보니 깔끔하게 빌드가 잘 된다.

[추가]

빌드는 잘 되는데 회사 플랫폼에서 사용하는 GoogleSignIn이 6.0.2여서 7.0.0으로 올리면서 API 호환이 안돼서 로그인 시도할 때 Crash가 나면서 앱이 강제종료 된다.

6.2.4
  2.x 버전을 허용하도록 GTMSessionFetcher 종속 항목을 업데이트했습니다. (#207)

GoogleSignIn에서 해당 빌드 오류 이슈를 해결한 버전은 6.2.4여서 6.2.4로 버전을 내렸다.

나처럼 다른 이슈로 7.0.0으로 못올리는 사람은 6.2.4로 한 번 시도해 보면 좋을 것 같다.

Unity 2021.3.19f1

Firebase 9.6.0

Facebook Android Plugin 15.0.2

[Case 1]

Firebase로 Facebook 연동을 했는데,

Facebook Web에서는 로그인이 잘되는데

위 스크린샷처럼 Facebook App이 설치돼 있는상태에서 App으로 로그인 하려하면 Invalid key hash 에러가 발생했다.

Facebook Web Login이랑 Facebook App Login이랑 Hash Key가 다른것 같다.

에러 메시지에 뜨는 key hash를 페이스북 개발자 페이지에 추가해주니 정상적으로 Facebook App 로그인이 됐다.

----

[Case 2]

- 스토어에서 받은 앱은 Facebook App 로그인 진행하려니 Key hash는 안보이고 위와 같이 에러 메시지만 띄운다.

- 혹시나해서 LogCat으로  보니 Key hash가 보여서 등록하고 정상 로그인 확인 함.
