cordova-plugin-dbmeter

This plugin defines a global DBMeter object, which permits to get the decibel values from the microphone. Although the object is in the global scope, it is not available until after the deviceready event.

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
    DBMeter.start(function(dB){
        console.log(dB);
    });
}

Installation

cordova plugin add cordova-plugin-dbmeter

The iOS part is written in Swift so the Swift support plugin is configured as a dependency in plugin.xml.

⚠️ Because this plugin doesn't support Swift 3 at the moment, the following preference has to be added in your project :

<preference name="UseLegacySwiftLanguageVersion" value="true" />

Supported Platforms

  • iOS
  • Android

Methods

DBMeter.start(success, error)

start listening.

DBMeter.start(function(dB){
  console.log(dB);
}, function(e){
  console.log('code: ' + e.code + ', message: ' + e.message);
});

DBMeter.stop(success, error)

DBMeter.stop(function(){
  console.log("DBMeter well stopped");
}, function(e){
  console.log('code: ' + e.code + ', message: ' + e.message);  
});

⚠️ If the DBMeter is stopped while is not listening, an error will be triggered and can be handle from the second callback argument.

DBMeter.isListening(success, error)

  console.log("Well done !");
}, function(e){
  console.log('code: ' + e.code + ', message: ' + e.message);  
});

⚠️ If the DBMeter has not been started once before deleting, an error will be triggered and can be handle from the second callback argument.
