i´m trying to send real time audio messages from a web site to a desktop applicacion (C#) .Its for a public address system, so desktop applicacion just recives audio stream and plays it through the speakers.
it's posible? what can I use for that purpose?
WebRTC can be used for that?
Thanks.
WebRTC used for browser based peer to peer communication. As per your requirement you can use WebRTC for real time audio messaging and can use Electron for user desktop app.Other approach would be can use Socket.IO for RTC for audio messaging.

How can i allow multiple users to stream audio coming from their machine over the network for multiple listeners i mean taking all the sound from their soundcard to the network,
I know this can be accomplish using icecast, edcast etc. but that will be only when the user installs these program to their device and start making configurations and a lot of work.
what i need is if its possible to do this without icecast just javascript, if we use webrtc it will be more like a voice call i guess,
but i need that audio streamed from device A to device B as if it was already in device B, am talking about playing music on the device and sound from mic at same time. is this possible with javascript? and multiple users can do this stream at same time.
taking all the sound from their soundcard to the network [...] without icecast just javascript
There is no Web API for capturing all sound the computer plays that I know of.
You could maybe make something like this with WebRTC or other web APIs if the user's sound drivers expose a recording device (like the "Stereo Mix" recording device of olden days) that the user selects for your web app to use.
(As an aside, Icecast itself doesn't care where the audio comes from, it just accepts and redistributes OGG or MP3 streams. It's up to the casting client to figure out where the audio comes from.)
I am on my way of learning javascript by developing some cool stuff like video conferencing app. I don't have much understanding of this webRTC technology so I am wondering if it is also possible to save video call to the server which has been taken place on webRTC based video conferencing app ?
Yes, it is possible. You can record each stream to blobs and push them to your server with websocket. You can then convert the blobs to a webm file.
Demo: video https://webrtc.github.io/samples/src/content/getusermedia/record/
I'm trying to develop a web application with WebRTC and I'm getting video from my webcam through WebRTC and I want to do live streaming on Facebook and YouTube with my browser I have searched python and node js libraries but I haven't find any library for that. I want to build an application like streamyard.com.
I have watched ffmpeg
You can do this using Pion WebRTC and ffmpeg!
I have created a demo here. If you have ffmpeg installed and the Go compiler this should just work!
This takes audio/video from the browser, and then constructs a webm in memory. It then passes this WebM to ffmpeg via a stdin pipe, which then is transcode and sent to Twitch!
There are a lot of optimizations we could make here (like taking H264 from the browser directly) but H264 isn't supported everywhere, so this just makes the sample easier to reason with.
Good Day,
I have a USB Audio device connected to my web server (RPi) running linux, apache2 and php.
I would like to display the sound level from the mic connected to the server via a webpage. I came across this html5 example which uses the:
navigator.getUserMedia
However this is for a microphone on the client side.
Can someone advise how I could achieve a similar page that instead displays the
level of the server side audio.
Thanks,
I want to make a very simple web app that takes the audio signal from the phone's microphone and varies some simple graphics on the page in as near to real-time as possible.
I'd prefer the app to be web-based (rather than iOS/Android apps) so that users can be directed to the page in a more rapid way. (I.e. go to sh.ort/url and the web app starts straight away)
Is this currently possible?
I'm not sure how well supported the web audio API is, or some of the more modern HTML5 features.
Thanks
This gives you a nice tutorial on how to record audio through the HTML5 API: http://www.html5rocks.com/en/tutorials/getusermedia/intro/
Unfortunately, as seen in this post, Apple doesn't support any API for this yet: Mobile Safari Audio Recording from Microphone
