Is there a concept called "white waveforms" in computer science? It sounds like the lecturer is speaking


  If you for example want to play a
  music file, mp3 file, well you know, given
  that you've taken a programming course
  before, all right? How would you do this?
  
  Well, you would look up on Wikipedia, what
  are the specifications of an mp3 file,
  and then you would sit down over a long
  weekend and you could probably write
  something in Python or in C, takes the file decodes it generates
  the white waveforms and so on.
  
  and it's
  not a big deal right after a couple days 
  you will have a program that takes that
  date and generates the output, that's fine.


The lecturer used a term "white waveforms". 

I know the visual of a waveform may look like this figure.



I also know .wave is one type of audio filename extension.

I am trying to figure out what "white waveforms" is.

I understand the approximate meaning that the lecturer is trying to say is playing mp3 file. 

So, what is "white waveforms"?
I suspect you might have misheard.  I suspect the lecturer said "takes the file decodes it generates the right waveforms and so on"  (right, not white).
