I have gone through the answer provided here for the difference. But I need to just play notification sound for like 2 seconds as an alert. No video or any other heavy loading.
This is the notification sound I am about to play.
ms-winsoundevent:Notification.SMS
The below is for MediaPlayerElement:
MediaPlayerElement mediaPlayerElement = new MediaPlayerElement();
mediaPlayerElement.SetMediaPlayer(new Windows.Media.Playback.MediaPlayer { AudioCategory = Windows.Media.Playback.MediaPlayerAudioCategory.Alerts});
mediaPlayerElement.MediaPlayer.AudioCategory = Windows.Media.Playback.MediaPlayerAudioCategory.Alerts;
mediaPlayerElement.Source = Windows.Media.Core.MediaSource.CreateFromUri(new Uri("ms-winsoundevent:Notification.Default"));
mediaPlayerElement.AutoPlay = false;
mediaPlayerElement.MediaPlayer.Play();
The below is for MediaElement:
MediaElement mediaElement = new MediaElement();
mediaElement.AudioCategory = AudioCategory.Alerts;
mediaElement.Source = new Uri("ms-winsoundevent:Notification.Default");
mediaElement.AutoPlay = false;
mediaElement.Play();
Can I use MediaElement since its a small audio or should I only use MediaPlayerElement as it is the one prescribed by Microsoft? which one is better to use in this case?
P.S.: I need to set audio category as Alerts in order to dim any background music.

Derive from official document,
In Windows 10, build 1607 and on we recommend that you use MediaPlayerElement in place of MediaElement. MediaPlayerElement has the same functionality as MediaElement, while also enabling more advanced media playback scenarios. Additionally, all future improvements in media playback will happen in MediaPlayerElement.
And it means that the new feature will be developed base on the MediaPlayerElement, we recommend using MediaPlayerElement that could make your app has longer life.

in UWP application, Sometime Playing sound is stop.
await Execute.OnUIThreadAsync(async () =>

StorageFile sf = await StorageFile.GetFileFromApplicationUriAsync(uri);
var stream = await sf.OpenAsync(Windows.Storage.FileAccessMode.Read);

I think, This UIThread job finish immediately.
but My sound file has 1 minutes length, Then,
The task was closed. then, Sound can not play by end.
How should I write to play sound ?
Refer to the following MSDN doc:Play media in the background. To support your music playing in background, you need to check the requirements from "Requirements for background audio". Actually you've mentioned that it is "sometime", so I'm not so sure whether you've already used the solution from the above doc. But if you haven't, you need to refer to that article, enable capbility and then manage both the transitioning and also notice the memory.
As explained here, OffsetSampleProvider can be used in order to play a specific portion of an audio file. Like this:
AudioFileReader AudioReader = new AudioFileReader("x.wav");
OffsetSampleProvider OffsetProvider = New OffsetSampleProvider(AudioReader);
OffsetProvider.SkipOver = TimeSpan.FromSeconds(5);
OffsetProvider.Take = TimeSpan.FromSeconds(8);
myWaveOut.Init(OffsetProvider);
myWaveOut.Play();
The above example will play an audio for 8 seconds, starting at second 5. However, if I want to play it again, it will not play, unless I set the Position property of the AudioFileReader to 0, and re-create a new instance of OffsetSampleProvider from it. So I would like to know if I'm missing something, or this is the way that OffsetSampleProvider should be used (and if it does, do I have to free any resources related to it).
You could copy the code for OffsetSampleProvider and add a Reset method to it. I'd also avoid using SkipOver for performance reasons and just set the CurrentTime of the AudioFileReader to 5 seconds directly before you play.
I receive over network PCM audio data stream and this part works fine so I am ending up with
DataReader incomming = args.GetDataReader();
byte[] RcvBuffer = new byte[incomming.UnconsumedBufferLength];
incomming.ReadBytes(RcvBuffer);
I have all audio data in buffer.
How I can play this through telephone Speaker ? Can you point me in some direction ?
Thanks
There're many ways to do that.
You can prepend the WAVE header to your data, and use MediaElement for playback, see the documentation for SetSource method.
If however by “telephone speaker” you mean the earphone, then it is only possible if you are creating a VoIP app.
It took a while but I sorted it, maybe someone else will need help in the future.
First Problem - since I just started app development for Windows Phone I have chosen Blank App (Windows Phone) instead Blank App (Windows Phone Silverlight) and I did not have access to many features that are available in Silverlight projects, so my suggestions for beginners: understand what each project is for.
Like Soonts said there are many ways to do this, this is one that I used.
I simplified this code and retyped this so there can be some typos.
using Microsoft.Xna.Framework.Audio;
using System.IO;
1) Create Stream to load your incoming data:
MemoryStream stream = new MemoryStream();
2) Load data from buffer to stream:
stream.Write(RcvBuffer, 0, RcvBuffer.Length);
3) I am using SoundEfect to play this through Loud-Speaker. Sample rate that I use is 8 kHz
SoundEffect sound;
sound = new SoundEffect(stream.toArray(), 8000, AudioChannels.Mono)
sound.Play();
Can anyone tell me the best approach to playing single-tone, audio (.mp3) files in a Windows Phone 8 app? Think of a piano app, where each key would represent a button, and each button would play a different tone.
I'm looking for the most efficient way to go about this - I've got 8 different buttons that need to play a different tone when tapped.
I tried using the MediaElement:
MediaElement me;
public MainPage()
{
InitializeComponent();
me = new MediaElement();
me.AutoPlay = false;
me.Source = new Uri("/Sounds/Sound1.mp3", UriKind.Relative);
btnPlay.Click += btnPlay_Click;
}
private void btnPlay_Click(object sender, EventArgs e)
{
me.Play();
}
But nothing happens, either in the emulator or on a device (testing w/ a Lumia 822). Am I doing something wrong here? It seems like it should be pretty simple. Or would using MediaElement even be the best thing to use for my scenario?
Would this fall under the Background Audio category? I've read through this example but it seems overkill for what I want to do.
I've also read about using XNA's SoundEffect to do the job, but then I'd have to convert my .mp3 files to .wav (which isn't necessarily a problem, but I'd rather not go through that if I don't need to).
Can anyone tell me either what I'm doing wrong in my example above or guide me to a better solution for playing quick <1s audio tones?
I had this problem before with MediaElement not playing audio files. After many attempts I found out that it only plays if it defined in the xaml and AutoPlay is set to true.
Try defining it in the xaml or you can just add it to your LayoutRoot.
var me = new MediaElement();
LayoutRoot.Children.Add(me);
me.AutoPlay = true;
me.Source = new Uri("Sound/1.mp3", UriKind.Relative);
I have had good luck just doing this piece of code in my app. But it may not work as well in your context, give it a whirl though.
mediaElement.Source = new Uri("/Audio/" + songID.ToString() + ".mp3", UriKind.Relative);
mediaElement.Play();
I would like to create a simple add-on that would play a different MP3 recording every time the user double clicks a word in a webpage he is visiting and selects a special option from the context menu.
The MP3 files are located on a remote server. Normally I would use JavaScript+Flash to play the MP3 file. In a Firefox add-on, however, I'm unable to load external scripts for some reason (playing the sound works fine if it's the webpage itself that loads the scripts, but of course I need it to work with every website and not just the ones that include the script).
So what's the easiest way to play a remote MP3 file in a Firefox add-on using JavaScript?
This may not entirely solve your question, as I don't BELIEVE it plays MP3s, but I'm not certain.
Firefox has nsISound, which I KNOW can play remote WAV files, as I've tested and proved it.
You may want to test it for yourself and see if it leads you a little closer!
var ios = Components.classes['#mozilla.org/network/io-service;1'].getService(Components.interfaces.nsIIOService);
var sound = ios.newURI("http://www.yoursite.com/snds/haha.wav", null, null);
var player = Components.classes["#mozilla.org/sound;1"].createInstance(Components.interfaces.nsISound);
player.play(sound);
Good luck, I hope this at least gets you close!
I know this is an old question, but if someone needs a way to do it:
let player = document.createElement("audio");
player.src = browser.runtime.getURL(SOUND_URL);
player.play();
There is one caveat: the user must have allowed autoplay on the website.
Here is a working code....
var sound = Components.classes["#mozilla.org/sound;1"].createInstance(Components.interfaces.nsISound);
var soundUri = Components.classes['#mozilla.org/network/standard-url;1'].createInstance(Components.interfaces.nsIURI);
soundUri.spec = "chrome://secchat/content/RING.WAV";
sound.play(soundUri);
var window = require('sdk/window/utils').getMostRecentBrowserWindow();
var audio = ('http://example.com/audio.mp3');
audio.play();
