Voice recording on iPhone by using Safari and HTML5 - javascript

I am developing a simple web application which only records a voice from microphone but I have some trouble.
HTML5 voice recording function works well on chrome and firefox desktop or android. But while using mobile browsers on iPhone even chrome and firefox it doesn't work.
I tried recorder.js and result did not change.
Is it possible to recording voice on safari or it is a missing function of safari or iOS?

May 2018 Update (because figuring this out has been tough with all the outdated info).
I found this demo that proves it is possible: https://kaliatech.github.io/web-audio-recording-tests/dist/#/test1

As far as I knew, even on the latest iOS (iOS 10), recording voice on iOS using HTML5 is still impossible. Since all the browsers on iOS are limited to use UIWebView which Safari on iOS uses as well, Chrome on iOS is not able to support any API that can be used for media recording.
For example, recorder.js which you used are built on Media Capture API. If you check caniuse.com, you will find this API is not supported on iOS. (Also check the issue here).
MediaRecorder API is also a promising API but still not supported by Apple's browser.
Check answers below for more information.
1. Record voice from IPhone using HTML5
2. Audio Recording html5 on iOS

It's now possible and "easy" to do on iOS11 for Safari! The mediaStream API is supported now. The mediaRecorder API however is not. This causes any existing examples out there to not work. So you'll have to implement your own mediaRecorder functionality by connecting the media stream to a webkitAudioContext ScriptProcessorNode and collect the stream buffer on the node's onaudioprocess event. You can then collect the iOS microphone's streaming audio data and do with it what you want, most likely merging it into a wav file for upload/download. This works for any browser that supports the Media Stream API.
Two gotcha's:
- iOS Safari likes to deallocate any AudioContext that wasn't created on the main thread (on a tap) so you can't initialize it on the device media access accepted callback.
- The scriptProccessorNode wont fire any audioprocessed events unless the input AND output are connected for some reason.

Since iOS11, Safari now supports Media Capture API:
New in Safari 11.0 – Camera and microphone access.
Added support for the Media Capture API.
Added ability for websites to access camera and microphone streams from a user's
device (user permission is required.)
Announcement by Apple - broken link as of Jul 2018

Therefore recorder.js will work now.

I'm using the new iPhone 11 ProMax, with iOS13.3, and have been trying to build out a web app with voice recognition services via HTML5 to work in safari or any browser on my iPhone. It seems iOS developers have blocked audio / video recording at the os level. There is a limited workaround however that might be useful for someone coming here as I did.

Basically, if you go into advanced settings for safari you can enable the mediaRecorder. Their demo works with video capture, I have not seen it with pure audio yet.

Safari on iOS 11 does NOT support the 2 standards which would make audio (only) recording possible (and easy to implement):
HTML Media Capture for audio (spec, correct syntax ) - audio recording should be passed to a native app which should pass the result back to the browser for upload (it works for video and picture)
MediaStream Recording API (spec, demo) - allows you to record to a blob directly in the browser. The recording can be downloaded or uploaded to a web server.

Chrome/Firefox won't play HLS video/mp2t video stream in HTML player

I’m currently working on a web application whose main purpose is streaming/timeshifting TV channels. Application is written in Javascript React framework and for web player we are using CookPete ReactPlayer with integrated hls.js. We have managed to successfully play live TV channels but unfortunately, we are experiencing some issues with timeshifting channels
Live streams are distributed over XtreamUI server as a m3u8 lists, and have this kind of format
example.org/live/username/password/channel_1.m3u8
So when a user is watching Live TV this kind of URL goes to the player source and CookPete player + hls.js are doing their magic with parsing/processing m3u8 list which results in playing video flawlessly.
Here comes the problem, for timeshift XtreamUI are using this kind of URL example.org/streaming/timeshift.php?username=XXX&password=XXX&stream=2&start=2020-04-26:19-23&duration=7
As you can see its PHP script which STREAMS raw bytes into the player. Here are response headers from /streaming/timeshift.php
As you can notice, the Content-type is video/mp2t which for some reason cannot be played in the browser environment.( Google Chrome, Mozilla Firefox, IE 11). This warning pops up.
On the other hand, Safari browser on Mac video is playing completely normal, but the request from Safari is a little bit different. This is a screenshot from Safari's console network tab. As you can see there are several requests with different byte-ranges.
We are seeking a solution which will provide playing timeshift video (video/mp2t content) in Google Chrome, Mozilla Firefox and IE 11. All suggestions/advices are welcome.
the Content-type is video/mp2t which for some reason cannot be played in the browser environment
This is because chrome and Firefox do not support mpeg transport streams, and safari does. hls.js works because it knows how to read a binary ts file, and rewrite it as mp4 fragment before sending to the the media source extensions buffer. You will need to do the same. Take a look at mux.js.
In Firefox install a codec by running this command.
sudo apt-get install libavcodec58
Install a similar codec in chrome too. It should fix the problem.

Record audio in a safari browser using HTML5?

I was searching for some solution to record audio inside of the browser and send for a webservice. I have found some solutions, but they only work for Chrome or Firefox. So, I wanna know:
Is there someway to record audio in SAFARI?
PS: I don't wanna use the tag video
What you are looking for is the getUserMedia API from WebRTC to access the user's microphone without any plugins. You can check out what browsers currently support the webrtc functionalities here: http://iswebrtcreadyyet.com/
At the moment it is not ready for safari.
The best support for webrtc is given by google because they are pushing this standard a lot.

Looking for a cross-mobile browser compatible way to record from a built in microphone?

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

Voice Record on Mobile Web Application

Question:
Is it possible, with some sort of technology, to integrate voice recording into a mobile web application?
Some background:
I have been working on a mobile web application just for my own enjoyment and research. Everything seemed to be working pretty slick with HTML5/CSS and JavaScript for the client application, although it looks like I need a third party technology for voice recording. I had a pretty good solution working with Flash, but after testing it with my IPhone, I had remembered that they don't seem to support flash which is disappointing because I had a pretty good solution going.
Voice Recording Requirements:
1. Must work with both iOS and Android.
2. Must work in most current versions of Firefox, Google Chrome, Internet Explorer, Opera, and Safari.
3. Must work within the framework of a mobile web application.
4. Must be able to record without being actively connected to the internet.
5. The client application shouldn't require the user to alter their phone OS.
I tried to be as specific as possible to assist in allowing you to answer this question accurately. If anything is unclear, just let me know in a comment below, and I will further clarify.
Check this http://www.html5rocks.com/en/tutorials/getusermedia/intro/
HTML Media Capture <input type="file">
Work for most of the mobile browsers, but it works not well because it will require native recording app and needs to active manually.
getUserMedia() and WebRTC
So far, only the Chromium support it well in mobile.
So, I gave up the web app. Hybrid app is the solution.
If you want to try the hybrid app for recording, you can check the Cordova Plugin https://github.com/emj365/cordova-plugin-audio-recorder-api that I created for recording task in the hybrid app.
It looks like in the years since asking this question a solution has surfaced. This solution has come in the form of MediaStreamConstraints dictionary audio property.
The Web API docs from Mozilla have a very nice example shown below:
document.getElementById("startButton").addEventListener("click", function() {
navigator.mediaDevices.getUserMedia({
audio: true
}).then(stream => audioElement.srcObject = stream)
.catch(err => log(err.name + ": " + err.message));
}, false);

https://developer.mozilla.org/en-US/docs/Web/API/MediaStreamConstraints/audio
If you want to record it as an audio, I think you can only make it for Chrome dev, Chrome canary, Opera next, and some mobile browser.
Using the WebRTC getUserMedia() API then make the blob URL of the audio data URL to save it.
If you want to record it as text maybe you can use <input -x-webkit-speech/> for webkit browsers. Make an event that make every-time it stop recording it'll add the currently recorded speech to an element and start recording again. Finally, make a blob URL to save it as a text file.

Audio streaming and voice recording via HTML and Javascript

I'm on a new project that requires to stream audio files (mp3) and record voice messages.. of course my first option was to use flash. But the problem is that the customer wants the website to be iPhone friendly.
Is there any technologie that allows me to play and record voice messages just with javascript/php/xhtml?
And of course, the website should be fully compatible with firefox, safari, internet explorer, etc.
I googled it and everything I found was flash-based.
but if you have any clue about it, please let me know.
No. Not even the new-ish HTML5 has any features to record audio. You'd need to go through Flash or Java - but that would rule out iPhone.
if you want to record sound you should do it with the new HTML5's api's, you can read more about it on
https://labs.ericsson.com/developer-community/blog/beyond-html5-audio-capture-web-browsers
However, this is theory, in reality no browsers support it and there is no way to do it. So in short: you cannot do what you ask.
What you could do is create an iPhone native app for those who want to use iPhone, and a flash website for those who want to access it with a regular browser.
