This function 1st appeared in this article by Sam Dutton and was later introduced in the MediaRecorder API spec. To check whether or not a browser supports a certain file format or audio codec when recording audio you can use the MediaRecorder.isTypeSupported() function. In terms of controlling the sample rate, one can specify it through the sampleRate audio constraint in getUserMedia() but it is not supported at this time by any browser. In terms of controlling the bitrate, the MediaRecorder API spec lists the audioBitPerSecond property but it is not supported at this time by any browser.

I’ve also noticed Firefox will record stereo audio (2 slightly different channels) when recording from a stereo capable recording device like the Logitech C925e or C920 (both have dual mics) or the 15″ Touch Bar MacBook PRO (3 mics). Firefox used Vorbis for audio recording in the 1st implementations but it moved to Opus since.
ogg containers (.webm is supported starting with Firefox 63). webm (Matroska) containers.įirefox will record mono Opus audio at 48kHz in. File formats, audio codecs & qualityĬhrome and Opera will record mono channel Opus (default) and pcm (wav, uncompressed) audio at 48kHz in. With the polyfill you’ll have about 83% coverage on desktop (IE would still not be supported) and 90% coverage on mobile when recording audio. Go on and give the online polyfill demo a try on your iOS device, here’s what you’ll see:

This polyfill is cool because it enables you to record audio on most mobile devices – Chrome on Android and Safari on iOS – without relying on the limited HTML Media Capture standard. It enables you to record uncompressed pcm audio in wav containers through the same MediaRecoder API. On Safari 11 (on both macOS and iOS) and Edge (non Chromium) you can use this neat polyfill. Edge 79 (Chromium) now supports the standard. On Edge the API is under consideration for implementation with 967 votes. On the other hand, WebKit is an open source project so anyone with mad skills can jump in and contribute. This issue on tracks the MediaRecorder API implementation in WebKit/Safari, if you need this API jumping in and leaving a comment will go a lot towards showing Apple developers we need this feature. The API has NOT been announced for Safari 12/iOS 12 due later this year. On Safari we might have to wait until Safari 13/iOS13. This gives you about 75% coverage on desktop (IE, Edge (non Chromium) and Safari do not support the standard) and 62% coverage on mobile (Safari on iOS does not support it). What’s not so cool is that on desktop computers it is only supported by:

We've also put together a better demo showing how to use the MediaStream Recorder API to record audio natively in the browser. You can cook up a working audio recorder in as little as 21 lines of HTML & JavaScript:Īudio Recording with MediaStream Recorder API by Octavian Naicu ( CodePen.

What’s cool about the MediaStream Recorder API is that it is built-in browsers so your web app will not make any extra HTTP requests or spend time loading external JS libraries.Īnother win is the number of code lines needed to set up a recorder.
We’re now going to take a look at native audio recording in the browser using the MediaStream Recorder API – a W3C standard.Īs of this writing the MediaStream Recorder API spec is in editor’s draft. We’ve previously covered how to record pcm audio using the JavaScript based Recorder.js, pcm, mp3 and Vorbis using WebAudioRecorder.js and mp3 audio using the Web Assembly based vmsg recorder. I want to make sure such basic issues are resolved before I really begin to build my own sites.This is the 4th post in our new recording audio in HTML5 series. Here's example of the CSS code as it appears in the tutorial:įont-family: 'acumin-pro-extra-condensed', sans-serif Īnd here's a screen shot of what the page looks like in Firefox. Others, like Gill Sans, did not.įor your reference, the applicable tutorial files can be downloaded from Some of my local fonts, like Chalet Comprime, worked. Just to be sure, I tested the page after modifying the code such that the page would use some different fonts.
I did not modify that part of the code from what already was provided from the tutorial, yet the font Acumin is not displaying correctly. Actually, I was practicing one of the tutorials found with Dreamweaver Help.
