Is it possible to Stream Audio form the Server to the client ?
Is there any example please ?

[duncanhoggan]

Yes it is possible

Server

io.on('connection', function (socket) {
  socket.on('client-stream-request', function (data) {
    var stream = ss.createStream();
    var filename = __dirname + '/downloads/' + <YOURSONG.MP3>;
    ss(socket).emit('audio-stream', stream, { name: filename });
    fs.createReadStream(filename).pipe(stream);
  });
});

Client

var audio = document.getElementById('player');
ss(socket).on('audio-stream', function(stream, data) {
    parts = [];
    stream.on('data', function(chunk){
        parts.push(chunk);
    });
    stream.on('end', function () {
        audio.src = (window.URL || window.webkitURL).createObjectURL(new Blob(parts));
        audio.play();
    });
});

AWESOME, i will try it soon ! <3 THANK YOU VERY MUCH!

[daslicht]

Is it also possible to send additional data with it like Metadata and is it even possible to send it to a specific point of time ?

[duncanhoggan]

You can emit it as a separate event or include it in the data object that is sent with the stream

ss(socket).on('audio-stream', function(stream, data) {}

[daslicht]

ok , but what about time sensitive data ?
Lets say I like to push metadata once the Playback has reach 1Minute, 30 Seconds of the source ?
Is at hat possible at all ?

[NecroKills]

Hi, Could you provide the full code?

[zoutepopcorn]

With this html part its working:

    <audio id="player" controls>
    <source src="" type="audio/mpeg">
        Your browser does not support the audio element.
    </audio>

[zoutepopcorn]

Example over here :D

[schnells]

is there a way to do it in real time?

[StefansArya]

There is a way to stream microphone in a real time, but I have small problem on my implementation..

Update:
I just uploaded this library, but it still need some improvement
https://github.com/ScarletsFiction/SFMediaStream

[avin3sh]

@StefansArya Can I use that library to stream binary blobs (sent as chunks of 3-seconds) ? Finding it very difficult to implement

[StefansArya]

Hmm, I think you could only send the buffer data (without media header). Because that's what I can get after calling mediaRecorder.requestData().

To stream chunks of 3 seconds you need to change the latency to 3000ms. I have an example on the repository that default to 100ms, maybe you can use that for experimenting.

And don't forget to set the similar latency to the streamer too.

[ithustle]

Yes it is possible

Server

io.on('connection', function (socket) {
  socket.on('client-stream-request', function (data) {
    var stream = ss.createStream();
    var filename = __dirname + '/downloads/' + <YOURSONG.MP3>;
    ss(socket).emit('audio-stream', stream, { name: filename });
    fs.createReadStream(filename).pipe(stream);
  });
});

@duncanhoggan , is it a good idea use sockets to build a streaming server to work as a streaming service on demand?

[daslicht]

that doesn't take bandwidth throttling into account no ? I just push as fast as possible no ?

[yusuf987]

Yes it is possible
Server

io.on('connection', function (socket) {
  socket.on('client-stream-request', function (data) {
    var stream = ss.createStream();
    var filename = __dirname + '/downloads/' + <YOURSONG.MP3>;
    ss(socket).emit('audio-stream', stream, { name: filename });
    fs.createReadStream(filename).pipe(stream);
  });
});

ss is not defined

[yusuf987]

var audio = document.getElementById('player');
ss(socket).on('audio-stream', function(stream, data) {

what is ss here ????

The solution @duncanhoggan provided is working. But what it do is it firstly read the whole file then after that it plays. But What I want is, I want to stream the file into chunks. There can be the delay for max 4-5 seconds.

Can anyone please provide the solution for this?

[avin3sh]

@rajatlnweb if you send it in chunks of 4-5 seconds, it will play it that way too.

[rajatlnweb]

@avin3sh , Can you please give me the code example as I am not able to find it out anywhere?

[zoutepopcorn]

Look above: #73 (comment)

[rajatlnweb]

@zoutepopcorn , I checked your code and it's not related to chunk based audio play at all.

[jojomoore2007]

Yes it is possible

Server

io.on('connection', function (socket) {
  socket.on('client-stream-request', function (data) {
    var stream = ss.createStream();
    var filename = __dirname + '/downloads/' + <YOURSONG.MP3>;
    ss(socket).emit('audio-stream', stream, { name: filename });
    fs.createReadStream(filename).pipe(stream);
  });
});

Client

var audio = document.getElementById('player');
ss(socket).on('audio-stream', function(stream, data) {
    parts = [];
    stream.on('data', function(chunk){
        parts.push(chunk);
    });
    stream.on('end', function () {
        audio.src = (window.URL || window.webkitURL).createObjectURL(new Blob(parts));
        audio.play();
    });
});

Could you do that client -> server -> client?
Like a peer-to-peer voice chat?
Just trying to make something for my non-programmer friends.

[duncanhoggan]

@jojomoore2007 For that use case I would recommend using WebRTC or something similar, it would scale much better and would be a true peer to peer implementation as opposed to the server middleman.

Hello
Streaming music synchronously from an mp3 file via an Angular + socket. io I have an mp3 file on my server.

And I want all my clients who visit that URL to listen to that music in sync.

That is.

Let's say the file plays for 6 minutes.

I start the song at 10:00 am

A request which comes at 10:03 am should start listening from the 3rd minute of the song.

All my clients should listen to the song in sync.

How can I achieve this with Angular and socket.io?

Hi @viradiya1993 , did you get any solution for this?

[Jobin-S]

isten to the song in sync.

I also need a solution for this. does anyone know how to implement this?
