Preface
Signal processing is one of my favorite topics. It is useful in many areas of
science and engineering, and if you understand the fundamental ideas, it
provides insight into many things we see in the world, and especially the
things we hear.
But unless you studied electrical or mechanical engineering, you probably
haven’t had a chance to learn about signal processing. The problem is that
most books (and the classes that use them) present the material bottom-up,
starting with mathematical abstractions like phasors. And they tend to be
theoretical, with few applications and little apparent relevance.
The premise of this book is that if you know how to program, you can use
that skill to learn other things, and have fun doing it.
With a programming-based approach, I can present the most important
ideas right away. By the end of the first chapter, you can analyze sound
recordings and other signals, and generate new sounds. Each chapter intro-
duces a new technique and an application you can apply to real signals. At
each step you learn how to use a technique first, and then how it works.
This approach is more practical and, I hope you’ll agree, more fun.
0.1 Who is this book for?
The examples and supporting code for this book are in Python. You should
know core Python and you should be familiar with object-oriented features,
at least using objects if not defining your own.
If you are not already familiar with Python, you might want to start with
my other book, Think Python, which is an introduction to Python for people
who have never programmed, or Mark Lutz’s Learning Python, which might
be better for people with programming experience.
