Class: CB_AudioFile

CB_AudioFile

Class to manage an audio file. Internally, it uses one audio API object which belongs to the audio API being used (when the audio API is changed, it keeps the old audio API objects just in case they are needed in the future when the audio API is changed again). Possible internal audio API objects are CB_AudioFile_API.WAAPI object for "WAAPI" (HTML5 Web Audio API), CB_AudioFile_API.SM2 object for "SM2" (SoundManager 2), CB_AudioFile_API.ACMP object for "ACMP" (Apache Cordova Media Plugin) or CB_AudioFile_API.AAPI object for "AAPI" (HTML5 Audio API).


new CB_AudioFile(filePath [, audioId] [, options] [, audioAPI] [, callbackOk] [, callbackError]) → {CB_AudioFile}

The constructor is recommended to be called through a user-driven event (as onClick, onTouch, etc.) if the "autoPlay" option is set to true, as some clients may need this at least the first time in order to be able to play the audio.

Parameters:
Name Type Argument Default Description
filePath string

The path of the audio file or a data URI. NOTE: Only some clients with some audio APIs will support data URIs.

audioId string <optional>
'CB_AudioFile_' + CB_AudioFile._idUnique++

Desired identifier for the audio object (can be a different element depending on the audio API used). If not provided, an automatic unique ID will be calculated. Note that it is not case sensitive and it should be unique for each object.

options CB_AudioFile.OPTIONS <optional>
CB_AudioFile#DEFAULT_OPTIONS

Object with the desired options.

audioAPI string <optional>
CB_AudioDetector.getPreferredAPI(undefined, false, null) || CB_AudioDetector.getPreferredAPI(undefined, true, null)

The desired audio API to be used. If not provided, it will try to calculate the best one for the current client by calling the CB_AudioDetector.getPreferredAPI function internally. Audio API support will depend on the current client being used. All possible ones are defined in CB_Configuration.CrossBase.CB_AudioFileCache_PREFERRED_AUDIO_APIS. For example: "WAAPI" (HTML5 Web Audio API), "SM2" (SoundManager 2), "ACMP" (Apache Cordova Media Plugin) or "AAPI" (HTML5 Audio API).

callbackOk function <optional>

Function with no parameters to be called when the audio has been loaded successfully, being "this" the CB_AudioFile object itself.

callbackError function <optional>

Function to be called if the audio has not been loaded successfully. The first and unique parameter will be a string describing the error found (if it could be determined), being "this" the CB_AudioFile object itself.

Source:
To Do:
  • Do not allow to create one object with an "id" which has already been used (unless the value is undefined, null...). Note that the "id" is not case sensitive and it should be unique for each object.
  • Send the CB_AudioFile object itself as a parameter when calling both "callbackOk" and "callbackError".
  • Think about allowing to define 'useXHR' and 'useCache' options (used by CB_AudioFile_API.WAAPI objects).
  • Method getCopy and static method filterProperties (similar to the ones from CB_GraphicSprites and CB_GraphicSpritesScene).
Returns:

Returns a new CB_AudioFile object.

Methods


checkPlaying( [callbackOk] [, callbackError] [, ignoreStatus] [, ignoreQueue] [, useCache]) → {boolean}

Checks whether the audio can be played or not. Recommended to be called through a user-driven event (as onClick, onTouch, etc.), as some clients may need this at least the first time in order to be able to play the audio. Also recommended to use before calling the CB_AudioFile#play method the first time. Internally, uses the "checkPlaying" method of the used audio API object. The checking action will only be performed if the value of the "status" property of the used audio API object belongs to the CB_AudioFile.UNCHECKED or to the CB_AudioFile.CHECKING value. After checking, if the audio can be played, the "status" property of the used audio API object will get the value of CB_AudioFile.LOADED. Otherwise, if it cannot be played, the "status" property of the used audio API object will get the value of {CB_AudioFile.FAILED}. Possible internal audio API objects are CB_AudioFile_API.WAAPI object for "WAAPI" (HTML5 Web Audio API), CB_AudioFile_API.SM2 object for "SM2" (SoundManager 2), CB_AudioFile_API.ACMP object for "ACMP" (Apache Cordova Media Plugin) or CB_AudioFile_API.AAPI object for "AAPI" (HTML5 Audio API).

Parameters:
Name Type Argument Default Description
callbackOk function <optional>

Function with no parameters to be called when the audio has been checked successfully, being "this" the CB_AudioFile object itself.

callbackError function <optional>

Function to be called if the audio has not been checked successfully. The first and unique parameter will be a string describing the error found (if it could be determined), being "this" the CB_AudioFile object itself.

ignoreStatus boolean <optional>
false

If set to false and the audio status is neither "UNCHECKED" nor "CHECKING", it will fail calling the "callbackError" function (if any). If set to true, it will try to perform the checking action regardless the status of the audio.

ignoreQueue boolean <optional>
false

If set to false and there is already the maximum number of audio files being checked (defined internally, depending on the audio API), the function will exit and it will call itself automatically again and again until the checking process can be performed (when its queue turn has been reached). This is done for performance purposes. Some audio APIs will ignore this parameter as they do not use checking queues.

useCache boolean <optional>
false

If set to true (not recommended) and the same audio file was checked previously, it will not perform the checking process again and it will do the same as the previous call. Some audio APIs will ignore this parameter as they do not use cache.

Source:
Returns:

Returns false if the checking could not be performed and failed. If it returns true, it can mean either the checking has been processed successfully or it will fail in the future, so it is recommended to ignore the returning value and use the callback functions instead.

Type
boolean

destructor( [stopSound] [, keepStoppedUnaltered] [, avoidOnStop] [, forceOnStop])

Destroys the audio file object and frees memory. Sets its current status to ABORTED (CB_AudioFile.ABORTED value).

Parameters:
Name Type Argument Default Description
stopSound boolean <optional>
false

If set to true, it will also call the "stop" method of the internal audio file object for the current API (stored in the CB_AudioFile#audioFileObject property). This method has the same parameters as the CB_AudioFile#stop method.

keepStoppedUnaltered boolean <optional>
false

Used internally as the "keepStoppedUnaltered" parameter to call the "stop" method of the internal audio file object for the current API (stored in the CB_AudioFile#audioFileObject property). This method has the same parameters as the CB_AudioFile#stop method. If the "stopSound" parameter is not set to true, this parameter will be ignored as the "stop" method will not be called.

avoidOnStop boolean <optional>
false

Used internally as the "avoidOnStop" parameter to call the "stop" method of the internal audio file object for the current API (stored in the CB_AudioFile#audioFileObject property). This method has the same parameters as the CB_AudioFile#stop method. If the "stopSound" parameter is not set to true, this parameter will be ignored as the "stop" method will not be called.

forceOnStop boolean <optional>
false

Used internally as the "forceOnStop" parameter to call the "stop" method of the internal audio file object for the current API (stored in the CB_AudioFile#audioFileObject property). This method has the same parameters as the CB_AudioFile#stop method. If the "stopSound" parameter is not set to true, this parameter will be ignored as the "stop" method will not be called.

load( [filePath] [, audioAPI] [, autoPlay] [, callbackOk] [, callbackError] [, ignoreOldValues] [, forceReload]) → {CB_AudioFile_API.WAAPI|CB_AudioFile_API.SM2|CB_AudioFile_API.ACMP|CB_AudioFile_API.AAPI|null}

Loads the desired audio file with the desired options. Recommended to be called through a user-driven event (as onClick, onTouch, etc.), as some clients may need this at least the first time in order to be able to play the audio. This method will be called automatically if the "autoLoad" option was set to true when calling the CB_AudioFile#setAudioAPI method. The audio API used will be stored in the CB_AudioFile#audioAPI property.
When this method is called, if the "status" property of the audio API object already has the "LOADED" status (defined in the CB_AudioFile.LOADED constant) and the "forceReload" parameter is not set to true, it will exit calling the given "callbackOk" function (if any) immediately. Otherwise, regardless the status, the status will be set to "LOADING" (defined in the CB_AudioFile.LOADING constant). After it, it will reach the "UNCHECKED" (defined in the CB_AudioFile.UNCHECKED constant). If the "autoPlay" parameter is not set to true, this will be the final status (and it will be necessary to call the "checkPlaying" method of the audio API object after it). After it and only if the "autoPlay" is set to true, as the "checkPlaying" method of the audio API object will be called internally, it will have the "CHECKING" status (defined in the CB_AudioFile.CHECKING constant) and finally the "LOADED" status (defined in the CB_AudioFile.LOADED constant) if all goes well.
Although it is not recommended to do so, if this method is called when the audio API object has the "UNCHECKED" status (defined in the CB_AudioFile.UNCHECKED constant), it will call the "checkPlaying" method of the audio API object internally.
Internally, it can use the CB_AudioFile#audioFileObjects property as a cache.

Parameters:
Name Type Argument Default Description
filePath string <optional>
CB_AudioFile#filePath

The path of the audio file or a data URI. NOTE: Only some clients with some audio APIs will support data URIs.

audioAPI string <optional>
CB_AudioFile#audioAPI

The desired audio API to be used. If not provided, it will try to use the previously-set one (in the CB_AudioFile#audioAPI property). All possible ones are defined in CB_Configuration.CrossBase.CB_AudioFileCache_PREFERRED_AUDIO_APIS. For example: "WAAPI" (HTML5 Web Audio API), "SM2" (SoundManager 2), "ACMP" (Apache Cordova Media Plugin) or "AAPI" (HTML5 Audio API).

autoPlay string <optional>
false

If set to true, it will start playing the audio automatically (by calling the CB_AudioFile#play method internally) unless the "ignoreOldValues" parameter is set to false and the previous audio was playing or paused. If set to true and the "status" property of the audio API object reaches to the "UNCHECKED" status (defined in the CB_AudioFile.UNCHECKED constant), it will also call internally the "checkPlaying" method of the audio API object before anything. Possible internal audio API objects are CB_AudioFile_API.WAAPI object for "WAAPI" (HTML5 Web Audio API), CB_AudioFile_API.SM2 object for "SM2" (SoundManager 2), CB_AudioFile_API.ACMP object for "ACMP" (Apache Cordova Media Plugin) or CB_AudioFile_API.AAPI object for "AAPI" (HTML5 Audio API).

callbackOk function <optional>

Function with no parameters to be called when the audio has been loaded successfully, being "this" the CB_AudioFile object itself.

callbackError function <optional>

Function to be called if the audio has not been loaded successfully. The first and unique parameter will be a string describing the error found (if it could be determined), being "this" the CB_AudioFile object itself.

ignoreOldValues string <optional>
false

If set to true, it will ignore the old values of the previous used audio API object. This means that it will neither continue playing if it was playing (changing the audio API on-the-fly) nor keep the paused status if it was paused nor copy its "loop" property to the new audio API object. Possible internal audio API objects are CB_AudioFile_API.WAAPI object for "WAAPI" (HTML5 Web Audio API), CB_AudioFile_API.SM2 object for "SM2" (SoundManager 2), CB_AudioFile_API.ACMP object for "ACMP" (Apache Cordova Media Plugin) or CB_AudioFile_API.AAPI object for "AAPI" (HTML5 Audio API).

forceReload string <optional>
false

Used internally as the "forceReload" parameter when calling the "load" method of the used audio API object. Possible internal audio API objects are CB_AudioFile_API.WAAPI object for "WAAPI" (HTML5 Web Audio API), CB_AudioFile_API.SM2 object for "SM2" (SoundManager 2), CB_AudioFile_API.ACMP object for "ACMP" (Apache Cordova Media Plugin) or CB_AudioFile_API.AAPI object for "AAPI" (HTML5 Audio API).

Source:
To Do:
  • Think about using the "forceReload" just after the "callbackError" to match the parameter order of the "load" method of all the audio API objects.

Time in milliseconds where we want the audio to start at. If not provided or it is not a valid number, it will use zero (0) as default which belongs to the beginning of the audio. If the value provided is greater than the "stopAt" provided, it will use the value set in the "lastStartAt" property of the used audio API object (which belongs to the "startAt" value the last time that the "play" method was called). If, even using the "lastStartAt" value is still greather than the "stopAt" provided, it will use the same value as the "stopAt" which means it will not play and will stop immediately. Used internally as the "startAt" parameter to call the "play" method of the audio API object.

Used internally as the "loop" parameter to call the "play" method of the audio API object.

avoidDelayedPlay boolean <optional>
false

If set to false (recommended) and the audio failed previously or was aborted (destroyed), it will try to load it correctly again automatically and play it after that if possible (this can take some time so the audio could start playing after a delay). Otherwise, if set to true and the audio failed or was aborted (destroyed), the audio will not play at all and the "stop" method of the used audio API object will be called immediately. Used internally as the "avoidDelayedPlay" parameter to call the "play" method of the audio API object.

allowedRecursiveDelay boolean <optional>
CB_Configuration.CrossBase.CB_AudioFile_AudioFileCache_ALLOWED_RECURSIVE_DELAY_DEFAULT

If the audio is looping, this will be called only once when the audio starts playing the first time and it will not be called next loops. Used internally as the "onPlayStart" parameter to call the "play" method of the audio API object.

onLoadError function <optional>

Function to be called if the audio cannot be played successfully. The first and unique parameter will be a string describing the error found (if it could be determined), being "this" the CB_AudioFile object. Used internally as the "onLoadError" parameter to call the "play" method of the audio API object.

isResume boolean <optional>
false

If set to true (not recommended) and it is a looping audio, the next loop will use the value of the "lastStartAt" property of the audio API object as the "startAt" parameter when it calls the "play" method again automatically (internally). Recommended for internal usage only. Used internally as the "isResume" parameter to call the "play" method of the audio API object.

Source:
Returns:

Returns the returning value of the "play" method of the audio API object. It returns false if the duration is 0 ("startAt" and "stopAt" are the same number), returns "-1" if the audio cannot be played and an error is detected or returns true otherwise. Note that even when it returns true there can be a non-detectable error and maybe the audio is not played.

setAudioAPI( [audioAPI] [, autoLoad] [, autoPlay] [, callbackOk] [, callbackError] [, ignoreOldValues] [, filePath] [, forceReload]) → {string}

Sets the desired audio API. This method will also be called automatically by the constructor. If the "autoLoad" parameter is set to true, it will call the CB_AudioFile#load method internally, changing the audio API on-the-fly, and the audio will try to continue playing if it was playing at the moment of calling this method. Check the CB_AudioFile#load method documentation for more information. If the "autoLoad" parameter is set to true, it is recommended to be called through a user-driven event (as onClick, onTouch, etc.), as some clients may need this at least the first time in order to be able to play the audio.
