It basically, consists in selecting the source from which we will capture the sound, specifying the format that adapts most to our need and indicate the name of the file and the location where we want to store the recording.

), you can download Free MP3 Sound Recorder. Only if getUserMedia() succeeds (user grants microphone access) we trigger the rest of the code.If you need a simple and free application to record from any sound source (microphone, line-in, multimedia application, Internet stream. set up the constraints object for audio only (see our audio constraints article for toggling advanced options like noise reduction and echo cancellation).The startRecording() function will do most of the heavy lifting in this demo. With our record & stop buttons referenced in JS we can add event listeners for when they’re clicked: recordButton.addEventListener("click", startRecording) stopButton.addEventListener("click", stopRecording) Var stopButton = document.getElementById("stopButton") Var recordButton = document.getElementById("recordButton") Var encodingTypeSelect = document.getElementById("encodingTypeSelect") holds selected encoding for resulting audio (file) MediaStreamAudioSourceNode we'll be recording var encodingType

The comments describe each variable in detail: var gumStream We’ll start out by defining a few variables and setting up references to those DOM UI elements. Now let’s move on to app.js and build our web based audio recorder. We’re inserting and app.js at the end to make sure they have access to all the DOM elements when run. Here’s how my index.html looks: Convert audio to: In index.html we need a select for the type of encoding, 2 buttons: start and stop, a list for showing the recorded files and a visible log too keep track of what’s happening.

I’m using index.html for a simple record/stop UI and app.js to host the code for the interface. To use the library you must 1st download the latest release (0.1.1 from 2015) from GitHub and set up your project folder. In practice, you’ll mostly see sample rates of 44100 (44.1kHz) and 48000 (48kHz). Regardless of the library, the sample rate used will be the one set in your OS for your playback device ( as per the spec). When recording to wav, audio data is recorded as 2 channel 16bit audio (CD quality) and thus will be exactly 10.582MB/minute at 44.1kHz but you can lower the number of channels from the WebAudioRecorder constructor to halve that size. The small code for capturing data as uncompressed wav is located separately in which comes in at just 2.6 KB minified and 1 KB gzipped. Also, keep in mind that Vorbis is mostly aimed at compressing music and audio in general, it’s not aimed at compressing speech like the way Speex is. The Vorbis encoder can encode mono or stereo sound and you can configure the bitrate from 45kb/s to 500kb/s. That’s 2 HTTP requests and 209KB in total when gzipped.

The MP3 encoder is locked at recording 2 channels but you can configure the bitrate from 64 to 320. That’s 2 HTTP requests and 126KB in total when gzipped. These libraries are loaded and used as Web Workers which prevents the browser tab from becoming unresponsive while the audio encoding is underway.Įven though the main JS file comes in at just 3.6KB when minified (and 1.21 KB when gzipped) unless you’re recording to wav, you do have to make extra HTTP requests and load the external libraries, and these libraries are quite big: Since JavaScript is slower than native code you should expect your encoding times to be higher. These libraries are Java Script versions of the popular LAME mp3 encoder and libogg/ libvorbis encoders obtained by compiling the original C code using Empscripten as (the asm.js subset of) JavaScript. WebAudioRecorder.js uses external JavaScript libraries to convert the raw audio to mp3 and Vorbis. When used in conjunction with getUserMedia() it can record the audio from the user’s microphone or webcam. WebAudioRecorder.js is a JavaScript library written in 2015 by higuma that can record audio and encode to common formats directly in the browser. The project is available on GitHub, link at the bottom, live demo here. There are 2 demos available for WebAudioRecorder ( the main one linked from GitHub that’s not working and a functioning one) but they’re fairly complex implementations and thus hard to get started with. We’ll be building a simple demo to help you get started with the library. In this blog post, we’ll cover using WebAudioRecorder.js to record mp3, vorbis and wav audio on your website. This is the 2nd post in our new recording audio in HTML5 series.
