Plugin Concepts

The plugin cordova audio recorder , can be used to record audio , on android and iOS . This plugin , provides an api , which is accessible , using the global object cordova.plugins.audioRecorder .

The api , consists of two functions , one for performing the recording , and one for stopping it .

For recording , the cordova.plugins.audioRecorder.audioCapture_Start function , can be used , it has the following signature :

cordova.plugins.audioRecorder.audioCapture_Start(audioCapture_Ended , audioCapture_Failed , audioCapture_duration )
/*
audioCapture_duration : 
    Number of seconds to perform audio
    recording . If non is provided , 
    the default is 60 seconds . 
audioCapture_Ended : 
    call back function , called when the
    amount of time allocated for recording , 
    audioCapture_duration , has elapsed . 
    It receives as argument , a String 
    containing the path of the recorded 
    m4a audio file .
    If cordova.plugins.audioRecorder.audioCapture_Stop 
    is  called , while performing recording , 
    then the registered methods ,
    using this function , are not called  , 
    instead the registered functions , using 
    cordova.plugins.audioRecorder.audioCapture_Stop
    are called .    
audioCapture_Failed : 
    If any error happens during the 
    act of performing the recording , 
    this method is called . It is passed.   
    a String , detailing the error .*/

To stop the recording, it is either stopped automatically , after the set amount of time has elapsed , or it can be stopped at any time , using the cordova.plugins.audioRecorder.audioCapture_Stop method ,which has the following signature :

cordova.plugins.audioRecorder.audioCapture_Stop(audioCapture_Ended , audioCapture_Failed )
/*
audioCapture_Ended : 
   call back function , called when successfully , 
   the audioCapture_Stop function , stopped the
   recording of the audio file . 
   audioCapture_Ended receives as argument , a 
   String containing the path to the recorded file . 
audioCapture_Failed : 
   Called when performing the recording has 
   failed . 
   It receives as an argument , a String , detailing 
   the error .*/

The recorded audio file is an m4a audio file , it is saved in the cache directory , of an application . The cache directory , might be emptied by the system , on low storage . Hence , for permanent storage , the recorded files , must be copied elsewhere .

For iOS , in the config.xml file , found in the root of the application , the following must be added , in between the widget element :

<edit-config file="*-Info.plist" mode="merge" target="NSMicrophoneUsageDescription">
    <string>Describe why microphone permission is needed</string>
</edit-config>
