Accessing Metadata, Audio Example Using Multitouch


When playing AAC files, you have access to metadata information that can be useful for your application. In this example, we are tracing the duration and the codec:

var connection:NetConnection;
connection = new NetConnection();
var stream:NetStream = new NetStream(connection);
// define the stream client property
var metaObject:Object = new Object();
metaObject.onMetaData = onGetMetaData;
stream.client = metaObject;“someAudio.m4a”);
function onGetMetaData(data:Object):void {
// audio duration
trace(data.duration*1000, “milliseconds”);
// codec
for (var prop:String in data) {
trace(prop, data[prop]);

Audio Example Using Multitouch

You can develop a musical instrument or device to trigger audio and music. Android devices only support two simultaneous touches; however, they support a range of gestures.

You can, for instance, use a left-to-right swipe gesture to turn the volume up and a right-to-left swipe gesture to turn the volume down.
