Get it work with sox-stream

[roccomuso]

It would be cool if we find a way to make it work with sox-stream. Any hint?

I wasn't able to get it working using this code:

var createBpmSink = require('../')
var sox = require('sox-stream')
var fs  = require('fs')
var src = fs.createReadStream('hellberg.mp3')

var transcode = sox({
        input: {
 		type: 'mp3',
                encoding: 'float',
		rate: 44100,
		channels: 2
        },
	output: {
		type: 'mp3'
	}
})

var bpmSink = createBpmSink()
src.pipe(transcode).pipe(bpmSink)

bpmSink.on("bpm", function(bpm){
   console.log(Math.floor(bpm))
   createBpmSink()
});

I got an issue:
RangeError: Index out of range

Changing the input channel i have this error on sox instead:

Error: sox WARN formats: can't set 1 channels; using 2

The only thing I can think of is attaching to the on('data') event and making sure that the data coming out of that library is the same as the original example.
