Simple WebAudio based resampling library.
#### Runs on all modern browsers which support WebAudio.
npm install audio-resampler
``
resampler = require('audio-resampler');
resampler(input, targetSampleRate, oncomplete);
input : Input audio file. This can either be a URL, a File object, or an AudioBuffer.
targetSampleRate : The target sample rate after the re-sampling process. This number is limted based on the browser implementation (usually >=3000, <=192000)
oncomplete: Callback when the resampling process is completed. The argument to this callback is an Object which supports the following methods:
getAudioBuffer : Returns the resampler AudioBuffer
getFile : Returns a ObjectURL of a WAV file created from the resampled Audio.
`
resampler = require('audio-resampler');
var URL = "https://dl.dropboxusercontent.com/u/957/audio/sine.wav"
resampler(URL, 192000, function(event){
event.getFile(function(fileEvent){
var a = document.createElement("a");
document.body.appendChild(a);
a.download = "resampled.wav";
a.style = "display: none";
a.href = fileEvent;
a.click();
window.URL.revokeObjectURL(fileEvent);
document.body.removeChild(a);
});
});
To test this repository, you can run a local server using the npm start` command which serves a simple drag-and-drop interface based webpage to resampler audio files.
