There are several libraries on github enabling this:

https://github.com/web-audio-components/simple-reverb

https://github.com/Dinahmoe/tuna

What they eventually do, is using the AudioContext api to create a convolver(which is also an option if you dont want to use the libraries).

The principle is:

1.)Load the file via Ajax, get the response, and use AudioContext.decodeAudioData saved to a variable.

2.)Create an audio context, and instead connecting it straight to .destination, add a a convolver using the .createConvolver()

The audioContext api documentation would help you a lot:
