//Because meyda v2 doesn't really have an offline extraction API, we need to manually require some stuff
var jsfft = require("./node_modules/meyda/node_modules/jsfft/")
var complex_array = require("./node_modules/meyda/node_modules/jsfft/lib/complex_array.js")
var extractors = require("./node_modules/meyda/dist/node/featureExtractors.js")
var meyda_utils = require("meyda").utils
//this is a simple class for streaming WAV data as Float32Arrays
//available at https://gist.github.com/jakubfiala/cb9de100fdd4f043d46e
//we're not going to use its streaming functionality for simplicity
var WavManager = require("./wav-manager.js")
var fs = require('fs')

//==========================================================
// CUSTOM JAVASCRIPT CONSOLE
// built by jakub fiala
//
// this small script intercepts the standard console methods
// and provides a way of accessing their messages,
// as well as stack traces, which is really cool.
// it formats the stack traces for popular browsers
//
// contributions welcome!

// creates a Sequence for the given AudioContext, which changes the `param` of the `node` according to a specified `seq` array with a given `smoothness`
// Example of a `seq` array:
// [ [0, 440], [1, 220], [1.5, 330], [2, 440] ]
// English: set the value to 440 immediately, then to 220 after 1 second, then to 330 after 1.5 seconds, then return to 440 after 2 seconds
//
// returns an object containing 3 methods:
//
// - `playOnce` will perform the sequence once
// - `loop` will loop the sequence indefinitely
// - `stop` will stop looping the sequence
