I know the question seems strange, but I want to know if it is possible in some maniere to speed up the speed of listening of a vocal message on instagram.
I am currently trying to create an mobile app that could do that, and much more. But this is the principal thing it needs. And i start the creation on the app by doing it on a cumputer to continue improving it.
Currently, I don't have a specific coding language, but it will be an app on mobile.
So, do you think that with something we could speed up the speed of listening of a vocal message on instagram?

We're building a video chatroom experience using OpenTok and while we have the fundamentals working, I'm finding that the noise floor is super high when we have many participants in the room publishing audio. Off-browser solutions like Zoom do not seem to have this high level of "white noise", but we seem to still be able to hear each participant immediately.
A secondary problem we're attempting to solve is that of the sheer number of subscriptions required: we're capped by OpenTok's limit of 3000 subscriptions per room. Currently, every client subscribes to every publisher's feed.
While experimenting with different approaches, it occurred to me that this is something all video chat applications would have to solve. Is there an optimal way to approach this currently? I can see the following solutions:
Mute the stream on the publisher side, essentially streaming silence until our voice activity detection (VAD) algorithm triggers.
Mute the stream on the subscriber side until VAD triggers. Because VAD is done on the publisher side, we risk losing the start of their audio.
Only subscribe to streams when VAD triggers. This is like the previous solution, but helps reduce our subscription count. However, I believe the latency and non-determinism here (each client would be individually subscribing, and this likely will be faster for some clients than others) would mean we'd certainly lose the start of speech.
What's the best way to approach this currently with WebRTC? We're targeting Chrome, Firefox, and Safari.

What timing... I literally just wrote a blog post about this: Best Practices for Multi-Party Video Conferencing with the Vonage Video API
I think it covers most, if not all, your questions. Also, be sure to join the Vonage Community Slack where our entire team & community can help.
A one place solution to your problem is OBS,( https://obsproject.com/ ) I guess you know it.
If you dont or if you have used it less, I would like to tell you that, it has immense feature if you explore it correctly and i feel that It will solve your need.
Do use and let me know if your problem is solved, or comment if its not solved.
Prewarning: I am a noob with development, I started doing web design when I retired from the Marines about 3 years ago. I specialized in Intelligence and Tactics, so not a computer user during that career. Fast forward to Today:
I work as an Exchange admin and migration specialist with GoDaddy, I have been through several Webdesign courses and learned a decent foundation of html/css/php however JavaScript, Nodejs, Java, Python, C++, and C# are all still things I am working on.
My issue: My lead wants to have a bot built that essentially posts messages in the #general group (I learned how to do this and actually setup a nodejs server within my test hosting server # GD and have a Joke bot running in my slack WS). The tricky part that I have been scratching my brain on is how to use an web API that GD has to monitor our call que, hold times, and agents online. I need to figure out how to get the bot to post a message regarding certain triggers automatically(exp. Hold time exceeds 10mins). I can not figure out whether to use a webhook, eventListener, or a direct bot auth'd into the GD api like my joke bot that links to chuckNorris jokes.
I appreciate all the comments truly, I have thick skin and know that I am late to the game on development. I want to build this for the experience and to integrate with slack, my end goal would be more projects to eventually become a Dev within GD.
I have a few thoughts that might help you.
Regarding these holdtimes, agents online, and call queues, think of these as events. Whenever these events occur, they should fire a payload (HTTP request) to your service that then posts messages to slack. I think you might need a slack bot token for this.
Many APIs have this functionality under webhooks. You provide them the URL to the endpoint your developing and theres usually a toggle to tell them that you want to start accepting events.
To get going on your service/bot, I'd recommend starting with learning about what these webhook event payloads will look like in terms of structure so that you can parse it.
If you have more detailed questions feel free to comment or message. Happy to help. I've written a slack bot or two.
We've made an application where two people can video chat with each other using TokBox, but are running into a lot of technical issues surrounding WebRTC and TokBox itself. I know that Twilio recently launched a Javascript version for their video service, but both TokBox and Twilio seem to be aiming for larger scale publish/subscribe operations. It also isn't as far along as TokBox.
Are there other services out there that can do web video 1 on 1's? Perhaps some that don't use WebRTC and therefore don't have the problems we are facing?
I can't help but to think back to ChatRoulette and similar apps.
If what you need is an application that needs to run within the context of a browser, then WebRTC is your only choice when it comes to the technology to use. There's just nothing else there now that Flash is officially dead.
If you need it to run purely inside a packaged PC/mobile application, then you can use something other than WebRTC, but I don't really see the need for that.
When using real time video technologies, one aspect to look at closely is the quality of the network you are using. The questions I usually ask myself are things like does Skype/Hangouts/FaceTime run any better? If the answer is "yes they do", then the problem is in the implementation you have done/used. If the answer is "no, they are just as bad" then you probably can't do a lot better either.
For alternatives, you can check out the vendors listed in this WebRTC Develoepr Tools Landscape: https://bloggeek.me/webrtc-developer-tools-landscape/
I don't know what you mean with "a lot of technical issues surrounding WebRTC and Tokbox itself", but I do know Tokbox handles millions of 1:1 streaming minutes every day, without issues, and it can even handle sessions with 1 publisher and 3000 subscribers at the same time, so, maybe the technical issues are not there, but in another place...
For sometime now I've been trying to do something that I never thought that it would be that hard: audio streaming. My objective is simple; a simple web app through which a certain someone can click a button and live-stream his own voice to other people using this app. It's an online classroom of sorts. Here's the details:
A broadcast/lecture is scheduled for a certain date and time (done)
A user logs-in as a teacher/instructor to a simple interface where he can click "start broadcasting" (done)
When the instructor clicks "broadcast" his voice is streamed to other users. Other student-type users can also log in and start listening to THE BROADCAST this teacher started. (and here is the trick!)
The broadcast itself should be automatically stored to a local file in the process. So that students can go back to it anytime.
Of course I spent so many hours googling and stackoverflow-ing this problem, and here is what I could understand so far:
If the starting point is the browser, I must use the GetUserMedia API, the result is raw PCM data that I can download, send to server or stream to others. (simple)
Offering the broadcast to the listeners (students) will be done via HTML5's Audio API. (simple)
WebRTC cannot help me here, because it's a p2p thing, there cannot be a server middling in the process, and I NEED TO KEEP A COPY OF THE LECTURE LOCALLY. (Here's a working example)
I can use tools like Binary.js to stream the audio binary data to the students, but this requires a file to be present already on the desk.
I need to convert the PCM data to a format like MP3 or OGG in the process, and not use WAV because it's much expensive bandwidth-wise.
I feel like it should be straight forward, but I cannot get it to work, I cannot piece all of this together and offer a stable and good experience for the user.
So again, I would love to know how to do the following:
Break the GetUserMedia raw data into packets and convert it to mp3, stream it to the server, where a script (NodJS probably) can store it locally and stream it whoever tuned-in, in real time.
I am open to whatever tool you recommend, I know that NodeJS will be present in the solution, and I am happy to use it. If the streaming could be done via a 3rd-party tool, I have no problem with that.
Thanks you in advance.
I see your comment about WebRTC, but I think you should investigate it more.
Like what you see here in this (old) post: http://servicelab.org/2013/07/24/streaming-audio-between-browsers-with-webrtc-and-webaudio/
Otherwise, you might have to go for a third party solution, like https://www.crowdcast.io/
(Even if you find a video-only solution, you can use a static picture or so for the video)
Event broadcasting is a good business for many companies. If it was that easy, there wouldn't be only few and well known competitors in the market.
I'm a newbie in Node.js and after doing initial learning on Node.js, I find it rather confusing to find out any best practices. My project requires to build a real-time notification system such that, when something happens at the server side or any of the connected clients, a notification can pop up at all connected clients. I couldn't find any official recommendations on what's the best approach and tools to take. I saw there are various frameworks written in Node.js seem able to do the job, but I'm hoping some one can give me some direction.
Thank you in advance.
Start with Angularfire if you want to code less.
You can create real-time apps without a backend part like so: https://github.com/tastejs/todomvc/blob/master/examples/firebase-angular/js/app.js
