  node.js audio-streaming red5 rtmp webrtc
  This is more a conceptual question rather than a direct “how to do this”. Is it generally possible to implement a flash-like solution to stream the audio (independent of where we get the stream data from, e.g. webRTC or other) in HTML5 and nodeJS/binaryJS. If so, how would you go about this?There has been only one inquire on stackoverflow found here and its from 2010. NodeJS and HTML5 have grown and matured since then.What people usually do: When using multimedia streaming (i.e. video or audio)

  php mongodb audio-streaming html5-audio
  I wrote a little audio streamer based on mongo and php with a player in HTML5. Every time I play something audio suddenly stops. I’m using php 5.3.3-1 as server on xubuntu 13.04 and MongoDB, everything is streamed locally. The code is on github at this address: link<?phprequire(“core/core.php”);$id = $_GET[‘id’]; $x = Track::object($id);header(“Content-Type: {$x->mime}”); header(“Content-Description: File Transfer”); header(“Content-lenght: {$x->size}”); if ( !empty($_GET[‘download’]) )

  asp.net streaming audio-streaming
  We have a need to stream live audio from remote devices and be able to listen to it in a web page. I can stream stored audio files, but the live stream has me a bit confused, since we will be adding the data at runtime. Can someone point me in the right direction to show me how to do this?Thanks

  I’m writing text editor that is supposed to actually SAY the current key that is pressed. I managed to do that, I even prepared files. And everything works just fine, but when the amount of symbols becomes more than 29, the compiler says: javax.sound.sampled.LineUnavailableException: unable to obtain a line at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.connect(PulseAudioDataLine.java:279) at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.open(PulseAudioDataLine.java:102) at org.cla

  audio streaming live audio-streaming
  I wonder if you could share your thoughts / resources about live audio streaming (to run on-line radio station). I have to admit, I am a complete newbie to the subject, so please excuse me lack of details. What are the most recommended platforms / software setups? Opinions based on personal experience would be highly appreciated.Thank you in advance.

  I am using DigitalDj’s AudioStreamer project (https://github.com/DigitalDJ/AudioStreamer) to stream audio in the background in my application. Everything works fine when the app is in the foreground but sometimes it gets crashed in back ground.

Maybe there is also a better solution than using webView to play rad

  android audio-streaming
  I’m making two apps – receiver and sender, each of which goes on an Android device. The sender should be able to stream local audio files to the receiver, over Wifi, preferably using UDP or RTP.I have made the receiver app, it runs fine on Internet radio stations and all, but the trouble now is in making the sender app. I haven’t been able to find any reliable resources online. Some of the resources I referred to and why they haven’t helped:#1 Audiotrack doesn’t support mp3, which would be a ma
