React record audio

Break out the champagne and doughnuts! Imagine a ski-run recorder that synchronizes video with GeoLocation data, or a super-simple voice memo app, or a widget that enables you to record a video and upload it to YouTube — all without plugins.

It's available now in Firefox and in Chrome for Android and desktop. See this bug. First up, instantiate a MediaRecorder with a MediaStream. Optionally, use an options parameter to specify the desired output format:.

For options it's possible to specify the MIME type and, in the future, audio and video bitrates. Use the static method MediaRecorder. Next, add a data handler and call the start method to begin recording:. This examples adds a Blob to the recordedChunks array whenever data becomes available. The start method can optionally be given a timeSlice argument that specifies the length of media to capture for each Blob.

Play the recorded Blobs in a video element by creating a 'super-Blob' from the array of recorded Blobs:. The ability to record audio and video without plugins is relatively new to web apps, so we particularly appreciate your feedback on the APIs. We'd also like to know what usage scenarios are most important to you, and what features you would like us to prioritize. Comment on this article or track progress at crbug.

By Sam Dutton. Useful guidance and analysis from web.This component is dependent on browser implementation of both the navigator.

The Recorder component provides an onMissingAPIs prop that allows developers to specify the appropriate behavior if a browser is lacking support for these APIs. If onMissingAPIs is undefined, it defaults to calling the alert function to notify the user to use either Chrome or Firefox. You can see the Recorder in action here.

Check out the source code here. If you're using Redux to handle your client-side state, react-recorder-redux provides actions and reducers for working with this library.

The onStop prop is the only required prop for the Recorder component. You can then use this Blob object to play back the recorded audio, download the recorded clip, upload the recording to a server, etc.

The onMissingAPIs prop is a function called when the browser fails to implement either the navigator. The function is passed the values for navigator. If onMissingAPIs is left undefined, the default behavior is to call window.

The onError prop is a function called when either navigator. The resulting error is passed to the onError function. A function called after a call to navigator. The function is passed the resulting stream, which can then be used with the Web Audio API to provide audio visualizations, etc. Useful for Redux-like environments where changes in state are communicated via props.

When the command prop is changed, the corresponding method is called. Allowed values are the method name strings ['start', 'stop', 'resume', 'pause'] as well as 'none'representing no method call. Developers can also call these methods directly by accessing the component's ref. The Recorder component does not have an actual representation in the DOM, returning only false in its render method.

Most cameras have a Auto Focus feature. It adjusts your camera lens position automatically depending on the pixels seen by your camera. Use the autoFocus property to specify the auto focus setting of your camera. Setting this property causes the auto focus feature of the camera to attempt to focus on the part of the image at this coordinate. Coordinates values are measured as floats from 0 to 1. Values are based on landscape mode with the home button on the right—this applies even if the device is in portrait mode.

On iOS, focusing will not change the exposure automatically unless autoExposure is also set to true. Specifies if audio recording permissions should be requested. However, this might not be always desirable e. Setting this to truemeans your app will not release the audio session.

Note: other apps might still "steal" the audio session from your app. Manually set camera focus. Only works with autoFocus off. The value 0 is minimum focus depth, 1 is maximum focus depth.

Use getSupportedRatiosAsync method to get ratio strings supported by your camera on Android. Overrides the type property and uses the camera given by cameraId. Use getCameraIds to get the list of available IDs.

A common use case for this is to provide a "switch camera" button that loops through all available cameras. Note: Variables such as flash might need to be resetted due to the camera not reporting an error when those values are not supported.

Use the whiteBalance property to specify which white balance setting the camera should use. Specifies the zoom of your camera. The value 0 is no zoom, 1 is maximum zoom. For a medium zoom, for example, you could pass 0. Value: optional float greater than 1.GoReact is the best way to give feedback on student videos.

This post will focus on getting the recorded audio into the same file format across browsers.

And yes, I spent a long time debugging in the browser. Here is the "simplest" way to record, play and download audio in Chrome this also works in Firefox but ogg format is used instead of webm.

react record audio

When you paste this example in the developer console it will ask for permission to record audio, record audio for 4 seconds and then append a HTML5 input audio element to the body which can playback the audio. You can also then save the audio to a file from this input element. Chrome and Firefox also have different audio recording formats but the same codec. You can test the supported recording formats in the browser by using the MediaRecorder function isTypeSupported. Remember : MediaRecorder!

Playing formats are much better supported than recording formats. See this excellent support media formats page. Recording audio in the same format across browsers is annoying, especially if you want the audio files sent to a backend. Converting to a consistent audio format on the frontend before sending to the backend is a good solution. This is how Facebook Messenger and WhatsApp do their voice recording on the web.

They use a WebWorker on the client for the possible heavy audio conversion process before sending it to the backend. Including a demonstration of how to do the encoding in a WebWorker.

Facebook messenger records the audio streaming data as before but then converts it in a WebWorker to a WAV format. They then send that format to the backend. They do something very similar to this project I found by a Googler who seems to specialise in Web Audio.

They use a library similar to opus. They also access the microphone raw data similary to this article by Google developers. I noticed they added a Butterworth Filter which I believe reduces background noise from the recording. Interestingly they don't also use navigator. Once converted, send the MP3 audio to the backend.

Here is a good explanation of how its possible to convert recorded audio to MP3. Another alternative solution would be convert those ogg and webm formats to a consistent format after receiving them in the backend. Avoiding any kind of client-side work to convert them. FFmpeg for example can do the conversion quite easily.

Recording in Chrome produces a webm file without any meta data about the duration of the recording. This means when Chrome plays back the recording it has no idea how long it is!

Ogg format on Firefox does not suffer from this. There is a bug in Chromium open for this issue. The downside is that the API is not yet supported in all browsers and recording formats are not consistent.
