I'm building a single page web app with node and express. I would like the user to be able to upload their own audio file so it can be played back in the browser.
I have tried using the <form> and <input> tags with type="file" but how can I get the audio file from that and use it in the browser for use with the web audio API?
Any help would be much appreciated thank you.
Check out the initDragDropOfAudioFiles() method in main.js in my Vocoder demo (webaudiovocoder.appspot.com, on github at http://github.com/cwilso/Vocoder). It sets up an element as a drag/drop receiver of audio files for use by Web Audio. It'll need a bit of generalizing to work for you, but it should be straightforward.
