# audioExt v0.0.3

 Sound External Loader/Unloader Manager for GameMaker Studio 2.3.1+

 

 This library helps load/unload, assign and manage ogg/wav files into neat lil structs to quickly utilize.



Note: ~~Only wavs currently support 3D audio. Ogg files are streamed in and do not have an option for 3D audio support support 3D audio out of the box~~ Both wav and ogg files support 3D Audio.

Additionally: ~~As of 2.3.6 (maybe earlier), `audio_exists()` does not correctly return true for ogg files, due to an internal bug with audio streams.

Instead, you should use `audioExtSoundExists()` and remove the ogg file with `audioExtOggRemoveStream()` from the database.~~ Fixed as of 2.3.7.



Note: signed 16-bit and unsigned 8-bit are only supported for wav files.



## Supported Platforms:

## Functions: 



### `audioExtSoundExists(name)`



Checks whether a valid ogg or wav struct exists with that name.



Returns: true/false.



### `audioExtSoundGet(name)`



Gets the sound struct from the list.



Returns: struct or `undefined`.



### `audioExtSoundGetSoundID(name/audioStruct)`



Gets the soundID from the list. If unloaded, will load in the sound first before passing the soundID.



Returns: soundID.



### `audioExtSoundLoad(name/audioStruct, ...)`



Loads in the audioStruct. Multiple arguments can be provided for each sequential audio.



### `audioExtSoundUnload(name/audioStruct, [forced])`



Unloads the audio. 



Optional Argument: `[forced]` is default to false. On true, it will automatically unload the audio. Otherwise, it'll wait until the audio is done playing.



### `audioExtSoundUnloadAll([forced])`



Unloads all currently loaded audio. 



Optional Argument: `[forced]` is default to false. On true, it will automatically unload the audio. Otherwise, it'll wait until the audio is done playing.



### `audioExtSoundRemove(name/audioStruct, ...)` 



Removes the audioStruct from the database. Multiple arguments will remove multiple entries.



### `audioExtSoundIsLoaded(name/audioStruct)`



Returns whether the audio is loaded in or not.



### `audioExtSoundClear()`



Unloads all audio entries from memory. 



### `audioExtStep()`



A necessary function to include in the step event of your project.



### `audioExtOggAddStream(filename, [preload] [name])`



Adds the ogg file as a streamable source. The audio **must** remain availabe at all times while it's currently in use.



Optional Argument: `[preload]` defaults to true. Adds an entry but doesn't actually load in the file.



Optional Argument: `[name]` defaults to the name of the file (excluding the extension).



Returns: struct or `undefined`.



### `audioExtOggRemoveStream(name)`



Removes the ogg file, if one exists. Throws an error if it doesn't.



Optional Argument: `[name]` defaults to the name of the file (excluding the extension).



### `audioExtWavAddBuffer(buffer, name, [is3D], [filename])`



Adds the wav file as a sound source from a buffer. The buffer itself is copied. 



`name` is the name that you want audioExt to recongize it as.



Optional Argument: `[is3D]` defaults to false. Determines if the audio file is intended for 3D Audio. Otherwise uses whatever the wav format determines. (Mono/Stereo)



Optional Argument: `[preload]` defaults to false. Adds an entry but doesn't actually load in the file.



Optional Argument: `[compressedInMemory]` defaults to false. Compresses data in memory automatically. Note: If `[preload]` is set to true, it will copy the buffer, but quickly compresses down in memory. Making it "unloaded".



Optional Argument: `[filename]` defaults to `""`. 



Returns: struct or `undefined`.



### `audioExtWavAddFile(filename, [is3D], [compressedInMemory], [name])`



Adds the wav file as a sound source from a filename. As this audio is loaded and handled in memory, you do not need to keep the file around afterwards.



Optional Argument: `[is3D]` defaults to false. Determines if the audio file is intended for 3D Audio. Otherwise uses whatever the wav format determines. (Mono/Stereo)



Optional Argument: `[preload]` defaults to false. Adds an entry but doesn't actually load in the file.



Optional Argument: `[compressedInMemory]` defaults to false. Compresses data in memory automatically. Note: If `[preload]` is set to true, it will load in the file, but quickly compresses down in memory. Making it "unloaded".



Optional Argument: `[name]` defaults to the name of the file (excluding the extension).



Returns: struct or `undefined`.



### `audioExtWavRemove(name)`



Removes the wav file, if one exists. Throws an error if it doesn't.



### `audioExtOggGetNames(name)`



Gets the name of all of the ogg files loaded in.



Returns: array



### `audioExtWavGetNames(name)`



Gets the name of all of the wav files loaded in.



Returns: array



### `audioExtOggScan(filePath, [preload])`



Scans all of the files within the chosen filePath and loads in any ogg files.



Optional Argument: `[preload]` defaults to false. Adds an entry but doesn't actually load in the file.



### `audioExtWavScan(filePath, [preload], [compressedInMemory])`



Scans all of the files within the chosen filePath and loads in any wav files.



Optional Argument: `[preload]` defaults to false. Adds an entry but doesn't actually load in the file.



Optional Argument: `[compressedInMemory]` defaults to false. Compresses data in memory automatically. Note: If `[preload]` is set to true, it will copy the buffer, but quickly compresses down in memory. Making it "unloaded".



## General Struct methods



`.getSoundID()` - Returns the SoundID from the struct. If unloaded, will load in the sound first before passing the soundID.



`.getName()` - Returns the name from the struct.



`.getFileType()` - Returns the filetype (wav/ogg) from the struct.



`.getFileName()` - Returns the filename from the struct.



`.getChannel()` - Returns the channel type from the struct. 



`.load()` - Loads in the audio.



`.unload([forced])` - Unloads the audio. If forced is set to true, it will automatically unload the audio. Otherwise, it'll wait until the audio is done playing.



## Wav struct specific methods



`.getBuffer()` - Returns the bufferID from the struct.
