Following is the code that i have written yet navigator.getUserMedia({audio: true, video: false}, function(stream) { webcamstream = stream; var media = stream.getAudioTracks(); socket.emit("sendaudio", media); }, function(e){ console.log(e); } }); How to convert stream into buffer and emit it to node.js server as stream comes from getusermedia function? Per @MuazKhan's comment,

Quick version: how to send correct Content-Range headers when don't know the body length? I have a FLAC file. I want to transcode it to MP3 and stream it to the user immediately. I have something like this so far: function transcode(file) { var spawn = require('child_process').spawn var decode = spawn('flac', [ '--decode', '--stdout', file ]) var encode = spawn('lame', [ '-V0', '-', '-' ]) decode.stdout.pipe(encode.stdin) return encode } var express = require('express') var app = express() app.get('/somefile.mp3', function (req, res) { res.setHeader('Accept-Ranges', 'bytes') res.setHeader(

I want to play my audio file as microphone input (without sending my live voice but my audio file) to the WebRTC connected user. Can anybody tell me how could it be done? I have done some following tries in the JS code, like: 1. base64 Audio <script> var base64string = "T2dnUwACAAAAAAA.."; var snd = new Audio("data:audio/wav;base64," + base64string); snd.play(); var Sound = (function () { var df = document.createDocumentFragment(); return function Sound(src) { var snd = new Audio(src); df.appendChild(snd); snd.addEventListener('ended', function () {df.removeChild(snd);}); snd.play(); return

I'd like my Android application to download an mp3 file from the internet and play it like a stream while downloading it. Is this even possible? How would I go about doing it? Essentially I want the user to be able to listen to the file instantly, but have it keep downloading to the SD Card even if he stops listening, so the whole mp3 file will end up on the SD Card either way. I don't believe android provides the functionality you're asking for. But there's one workaround I know of that might work. http://code.google.com/p/android/issues/detail?id=739 is an open ticket with a lot of

We need some heads up for a hobby web project. At this stage we want to detect client's sound card and direct whatever coming from sound card to server to process audio. And low latency is an important issue for us. So we need your suggestions for language, library etc to use. If you can give us some information about the big picture, then we can study on our own. Capturing Audio Client-Side You can use the Web Audio API along with getUserMedia (generally considered part of the WebRTC feature set) to capture audio (and video if you want it) from the user. Here is a code example from the

So I am using AudioRecord from Android to record raw bytes and for writing them into a .wav file. Since Android has no support for this I had to write the .wav file headers manually with the following code: randomAccessWriter.writeBytes("RIFF"); randomAccessWriter.writeInt(0); // Final file size not known yet, write 0 randomAccessWriter.writeBytes("WAVE"); randomAccessWriter.writeBytes("fmt "); randomAccessWriter.writeInt(Integer.reverseBytes(16)); // Sub-chunk size, 16 for PCM randomAccessWriter.writeShort(Short.reverseBytes((short) 1)); // AudioFormat, 1 for PCM randomAccessWriter.writeShort
