tea.xyz Spam Plagues npm and RubyGems Package Registries
Tea.xyz, a crypto project aimed at rewarding open source contributions, is once again facing backlash due to an influx of spam packages flooding public package registries.
@accentdotai/recorderjs
Advanced tools
Readme
This library drives the audio recording capabilities of the language learning app Accent.ai.
Note: This repository is the most up-to-date and functional fork of @mattdiamond's Recorderjs.
var rec = new Recorder(source [, config])
Creates a recorder instance.
exportWAV
.exportWAV
. Defaults to 'audio/wav'.rec.record()
rec.stop()
Pretty self-explanatory... record will begin capturing audio and stop will cease capturing audio. Subsequent calls to record will add to the current recording.
rec.clear()
This will clear the recording.
rec.exportWAV([callback][, type])
This will generate a Blob object containing the recording in WAV format. The callback will be called with the Blob as its sole argument. If a callback is not specified, the default callback (as defined in the config) will be used. If no default has been set, an error will be thrown.
In addition, you may specify the type of Blob to be returned (defaults to 'audio/wav').
rec.getBuffer([callback])
This will pass the recorded stereo buffer (as an array of two Float32Arrays, for the separate left and right channels) to the callback. It can be played back by creating a new source buffer and setting these buffers as the separate channel data:
function getBufferCallback( buffers ) {
var newSource = audioContext.createBufferSource();
var newBuffer = audioContext.createBuffer( 2, buffers[0].length, audioContext.sampleRate );
newBuffer.getChannelData(0).set(buffers[0]);
newBuffer.getChannelData(1).set(buffers[1]);
newSource.buffer = newBuffer;
newSource.connect( audioContext.destination );
newSource.start(0);
}
This sample code will play back the stereo buffer.
rec.configure(config)
This will set the configuration for Recorder by passing in a config object.
Recorder.forceDownload(blob[, filename])
This method will force a download using the new anchor link download attribute. Filename defaults to 'output.wav'.

This package can be used both as an ES6 Node.js module and a Browser library.
Node.js imports use the file src/recorder.js
.
NOTE: Currently this package can only be used under Node.js apps compatible with ES6.
Webpack is used to build the browser-compatible lib/recorder.js
file which is later uglified (using uglify-js
) into dist/recorder.min.js
.
The following scripts are defined within package.json
for ease of development:
npm run lint
npm run build
For more info on how these work simply checkout the script definitions within package.json
.
