Could anyone help me with a simple code?

You can use Independent Components Analysis to solve the Blind Source Separation problem (the "cocktail party problem"). Here are some links:

It can be done, but I doubt the math (maths, plural, for our UK friends) or the code will be "simple" as you requested. Good luck with it though.

I only need ad algorithm to segment an audio stream into portions. I think fastIca is for another aim

Are you talking about just cropping your signal in time, like

subsignal = signal(200:4200);

or something like that, rather than actually extracting different types of sounds from the same segment of audio?
