Audio Manager Documetation




Firstly, thank you for deciding to use our asset for your project. If you like our asset, feel free to leave us a review! If you find that our asset is not up to scratch or find and issue please do let us know either via our email: and we will do our best to help you with the issues you are facing.



Import all files from the Audio Manager package into your project. The files are all contained in their own file structure, you can just import it as is, or merge the induvial folders into your own project. Once this is done you’ll need to run the setup to start using the asset. If you plan to store your audio clips out side of “Assets/Audio” then you will need to change the base scanning directory from the Audio Manager Global Settings, found under Tools/Audio Manager | CG/Global Settings. If you just want the default directory you can just move on to the setup.

First add the audio manager component to any gameobject you like. We recommend putting the script on a empty gameobject. Once added the inspector will show up asking for an Audio Manager File before moving forward. If this is your first time adding an Audio Manager script to an object, you’ll find that the field may be populated for you by the scripts automatic setup which generates the file structure for the asset and makes a default Audio Manager File for you to use.

Next you’ll need to assign the prefab that is to play the audio when you request it. We provide a correctly setup prefab in the package which we recommend you use with the asset. If you have lost it or are upgrading from an older version you may find your prefab is outdated. See the Audio Prefab section for more on how the prefab should be setup.

You can also assign audio mixers should you wish, though these are optional and are not required to use the manager to function. When you add mixer groups here you can use the ID listed next to them to use them when calling for a clip to be played without needed a direct reference to the mixer in the script you are calling from.

From here you are almost ready to use the Audio Manager. The inspector should now show the options for directories & clips. Open the directories tab by pressing the show directories button if it is not already open. Here you’ll see an empty field and a button to continue. If you audio clips are going to be stored in the base scan directory you can just press the continue button and the manager will scan and add any clips it finds. However if you want to use a folder structure you’ll need to define the subdirectories here. See the How Scanning Works section for examples of how to write these. You can add or remove elements with the + & – buttons along each row. When all the directories are valid the manager will scan, you may notice a little editor lag as this runs.

From here all of the clips in the directories selected should be in the clips section, press the show clips button to reveal the clips if needed, with both the directories and clip sections you can hide them to reduce the space the inspector takes up when not needed. Assuming you see the clips all listed you will be ready to use the Audio Manager.


Basic Usage

The Audio Manager has a variety of methods you can use to play audio clips in your scene. There are two main ways of passing in params, either but individual params or with a hashtable. We provide a version of a hashtable called AudioArgs which will make sure the params you pass in are setup correctly, such as fixing formatting issues you may accidently make. To play any method you will need a reference to the script, this can either be the static instance provided or a direct reference made by yourself. Below is a few examples of how to play a clip called MySound:

// Reference to script
public AudioManager audioManager;
// This will play MySound at the default volume of 1 and default pitch of 1.
// This will play MySound at the volume of 0.5 with the default pitch of 1. You get the idea…..
audioManager.Play("MySound", .5f);
// Using the static instance
AudioManager.instance.Play("MySound", .5f);

Audio Args & Hashtables

As of 2.5.0 we have changes how the methods in the main audio manager script work. You can now use the AudioArgs static method or a Hashtable to define all the params for the method. With this change we have also added a few additional params, such as priority and reverb & spatial blend that are not in our standard methods which allows for full customisability. This is also where our play at position and on gameobject methods have been moved to. In 2.5.1 we have moved the AudioArgs to the Audio Helper static class so it can be used without the Audio Manager being static. To use the arguments you can do any of the following, note that inn 2.5.0 you need to pass string values with PascalCase, from 2.5.1 or later string values should be in lowercase:

// Using the static Audio Helper class
Play("myClip", AudioHelper.AudioArgs("position",, "time", 1f));
// Using a Hashtable
Play("myClip", new Hashtable("position",, "time", 1f));

You can also cache a reference for better performance and easy editing like so:

// With Hashtables
// Set in start/awake 
var table = new Hashtable();
table.Add("Time", 1f);
// When you want to play a clip...
Play("myClip", table);

Audio Manager File


The Audio Manager File Scriptable Object stores all the audio that has been scanned by the manager instance that is using said file. This file is required for the Audio Manager and Audio Player scripts to function. You can have multiple files and multiple instances of the manager running at once should you need to as each instance will run independently.

You can create an Audio Manager File by using the create asset menu following the path shown above. One of these is created for you when you run the setup mentioned before. Most projects will only really need one file. However the option is there to create more.


The Audio Manager File (AMF) has a custom inspector which better display the information it holds for the user as well as explains what each field does.

⚠️ If you haven’t imported the AudioManagerFileEditor.cs script into your project you will not see this inspector. Instead you will see a normal scriptable object inspector.

There are two tabs in the inspector. The first tab is the settings that this AMF is setup with, all of these values are handled by the inspector in the Audio Manager script and should be left as is in the file, editing this here can cause errors in the inspector of the manager. The second tab shows all the clips that the AMF holds, this is what is used when you call for a sound the be played. You have the option here to clear and re-scan this library from the AMF should you need it.


Audio Manager Settings


The audio manager settings are a set of global options that effect the asset as a whole. You will only have one of these per project and don’t have the option to make your own. When you run the setup for the asset it will make one of these for you if there isn’t one in the project and it will sit in the same location as the AudioManagerEditor.cs class is.


You can edit the options either form the scriptable object or via the editor window. The editor window provided more context on each option and what they do so it is recommend you use that over the scriptable object. The editor window can be accessed either by the custom inspector on the settings scriptable object or via the navigation bar under Tools/Audio Manager | CG/Global Settings.

Base Audio Scan Path – This controls the base directory that is used for all audio in the project. By default it is set to /audio in the assets folder of your project. You can change this to any directory in the assets folder of your project, though we recommend you only change this if necessary and before actually using the asset to avoid issues with existing audio manager files.


Audio Manager


The Audio Manager script is the main script for the asset. it handles the scanning and setup for audio in your project. When you first add the component to a GameObject you’ll be greeted by a display similar to what you can see on the left here. This script requires an Audio Manager File to work, it will generate one when you first add the component.

Setup Details

We go through this in the Setup section, but here is a more detailed rundown about what is what.

When you first add the script, it run the initial setup for the asset by creating the paths for the Audio Manager Files in the defined base scan path, which is just /audio in your projects assets folder by default. If it is your first time adding the component, it will also make an Audio Manager File for you and place it under the base scan path folder generated which by default is under /audio/files and assign it in the inspector for you ready for use.

The audio manager has a few options that need setting up before it is ready to use. These steps are only needed on the first run, once you’ve done this you won’t need to repeat the steps unless you change the Audio Manager File the manager uses with a fresh one, in which case you may need to repeat the setup.

  • Firstly you can choose to have the Audio Manager be static or not. If you wish to use the static instance then just press the button and wait for the editor to refresh, once done the button will change to a red disable button. Note that you may need to restart Unity and/or your IDE of choice to get the instance via your IDE auto complete.
  • Next you will need to assign the audio prefab, we provide one with the asset package, see the Audio Prefab Setup for more information. This is used to play the sounds you request.
  • Next you can setup and Mixers you wish to use with the manager. You can add additional mixers with the + Button next to the any mixer field. Each mixer is assigned an ID, which works like a collection index, starting at 0 and going up the more you add. You use this ID to use mixers when calling sounds to be played through the manager.
  • Next you’ll need to press the show directories button to reveal the scan directories window. Here you can set all the directories from the base directory you wish to scan. If you wish to get audio from the base directory then you can just press continue right away. Once again you can add more via the + Button.
  • Once you have pressed the continue button the Audio Manager will have scanned all the clips in the defined the directories and display them for you. If it runs into any errors, the asset will show a message explaining what has gone wrong most of the time.

You are now set the use the Audio Manager and the rest of asset scripts that require the Audio Manager File to operate.


Manager Settings
  • Enable/Disable Static Instancing – toggles the static instance on the audio manager script, it is off by default but can be enabled if you want to use a static instance for referencing. When toggling, the editor will take a little time to reload. Note that if you use the instance, you can only have 1 audio manager script in the game. Any extra version will auto-destroy on enable.
  • Audio Manager File – The audio manager file to read/write from.
  • Audio Prefab – The prefab to spawn when you call for a clip to play through the manager.
  • Mixers – The audio mixer(s) to use when playing the clips through.
  • Directories – A collection of directories that are to be scanned, a blank field just scanned the base location. You can’t have duplicates and the manager wil warn you if you do.
  • Clips – Each field will show a play button in green and a clip name which is the name you need to call to play the clip. You can copy directory from this field. Pressing the green button will preview the clip.

Audio Prefab


The audio prefab is used to play the clips that you request from the Audio Manager & Audio Player. These objects spawn in when you call for a clip to be played and when finished the object with disable for re-use.


We provide a fully setup prefab in the asset package, though should you wish to create your own or may alternative versions you will need the following components attached:

Audio Source

The source that plays the clip, this is all setup when you call for a clip to be played.

Audio Clip Player (prev. Audio Removal)

This script just handles the clean-up of the object once the clip has finished playing ready for re-use. This is a required component as the audio manager can’t function properly without it.

Audio Events

If you wish to use the OnClipEnded Action then you will also need this script. If you don’t use the event they you will be fine to not add this script.


Audio Player


The audio player script lets you play clips from a Audio Manager File library from the inspector. This is designed for use with UI elements and UnityEvents. This is designed to just be a basic stopgap as you’ll more commonly want to write your own implementation for playing specific audio.


The inspector for this script should be setup for how you want your audio to play when you call the method to play the sounds on it.

  • Audio Manager File – the library to read from for the clips.
  • Audio Mixer – the mixer group to play the clips through.

The next section defines all the clips that are to be played, you can add or remove elements with the + & symbols. Each clip has several fields, below is what each of them are:

  • Clip Name – The name of the clip you want to play, this has to be a clip that is currently in the audio manager file entered at the top of the player for it to work.
  • Volume – The volume the clip should play as, this is limited between 0-1, use the mixer group, or increase in the audio clip file to change it further if needed.
  • Pitch – The pitch for the clip to play at.

The rest of the settings are optionall for each clip but allow them to be played using the from time and with delay setups like in the main audio manager script.

  • Play From Time – The start time clip should play from.
  • Play With Delay – The delay there sould be before the clip should play.

Music Player


The music player is a script that allow you to manage some basic background music within your games. The script lets you change the track via code with a few transitions to choose from. This script has a static instance by default and is not affected by the main Audio Manager static instance toggle.


The inspector for this script should be setup with the first track you wish to play, the rest of the tracks should be stored in your own scripting to be inserted into the player when needed.

  • Track To Play – the track that will play when will script is first called
  • Music Audio Mixer – the audio mixer to play the clip from

The settings for the player allow you to change how the player plays your tracks, You can edit all the values when through code.

  • Play On Awake – should the click play on the Awake() method
  • Intro Transition – the transition the player uses when the track first plays
  • Transition Length – the length of the transition for changing tracks
  • Track Volume – edits the volume of the clip between 0-1
  • Track Pitch – edits the pitch of the track

The looping of the track you select is optional, should you want to use it you’ll need to set it up for each track you want to use. When calling to play a track in code you can set the start and end times.

  • Should Loop Track – should the track loop once it reaches the end of the audio clip
  • Start Track At – the time in seconds where the clip should start from
  • Loop Track At – the point in seconds where the track will loop from


By default the script scans the “/audio” directory if you have left a directory field left blank, you can change the path via the Audio Manager Global Settings which we recommend you do before scanning for the first time. to go to any sub-directory within the “/audio” folder, or add additional directories using the inspector display. This field is not case sensitive as shown below:

  • Example 1: mygame – “/audio/mygame” will be scanned
  • Example 2: MyGame – “/audio/mygame” will be scanned (capitals are ignored)
  • Example 3: MyGame/SFX – “/audio/mygame/sfx” will be scanned

The script will automatically update with the new sounds once you have entered a valid directory. Once scanned the script will list all the audioclips it has found. This will update on the fly when you add new files into your scanned directory with the audio manager selected.

The scripts have a selection of error messages in the form of console warnings, all errors from this script come with the prefix “Audio Manager |” so you will know it is from this package. Most errors shouldn’t come up, but they should explain what you’ve done wrong and how to fix it.

  • Warning Code 1: Make sure you have a sound prefab assigned to the AMF you are using, this is caused when there is not prefab found.
  • Warning Code 2: Make sure you have spelt the clip you want correctly, this warning shows up if the audio could not be found in the audio manager when called.
  • Warning Code 3: Could not find audio mixer, Please ensure the mixer is in the inspector and you have the right ID.
  • Warning Code 4: No AudioSource Component found on the Sound Prefab. Please ensure a AudioSource Component is attached to your prefab.

This can happen if you switch the build up

The audio manager will scan all valid audio file types that work with unity. There are a few reasons why a clip won’t scan. Try some of the steps below if you are having this issue.

  • Make sure the file type is accepted by Unity.
  • Make sure the clip name is not the same as another in the project.
  • If updating a clip with a new one with the same name, delete the old one and let the audio manager rescan, then add the new one.

There can be a few reason why a clip won’t play:

  • Check that you have spelt the clip name correctly.
  • Check that the clip is present in the audio manager file you are using.

This is due to you having the call in an update() or similar, if you have the call in update you need to have either a Boolean or a coroutine to stop it been called more than once.

If this has happened, please sent me screenshots and ways to replicate the problem so I can fix it. email:
