overlap-add

Perform additive synthesis from a stream of frames. This is something like inverse of frame-hop.

example

//First create the push-frame function
var pushFrame = require('overlap-add')(256, 64, function(data) {
  console.log('got a frame:', data)
})
 
//Then stick frames into it
pushFrame([...])

Install

npm install overlap-add

require("overlap-add")(frame_size, hop_size, ondata)

Performs additive synthesis on a sequence of frames.

• frame_size is the size of each frame
• hop_size is the size of a hop between successive frames
• ondata(frame) is a callback that gets fired each time a frame is full

Returns A function that you can call to push a frame of data into the stream.
