In this post we will understand what it means to say “this song has a lot of high frequencies”, then hunt and capture the waveform that allows us to say this! Some Python code will be used, but understanding it is not necessary. Footnotes are more technically advanced.
The x coordinate of the circle… is frequency?!
Sine waves are widely agreed to be the “most basic wave” when doing anything involving periodic signals – whether radio circuit analysis or music synthesis. Indeed, the sine wave is pretty simple as far as waves go, and quite smooth to boot, but I’ve always asked myself: why the sine? There are many other simple, basic waves that could be used as a basis for a theory of frequencies.
… and yet mathematicians and engineers, even musicians, always choose the sine. What makes the sine so special? Could a theory of frequency analysis be built around a different waveform, and how different would it be? How different would music sound if we used another simple waveform as our basis?

I started exercising my idea muscles a few days ago.
Every day I think of 10 startup ideas and develop one into a business model. Some will be published here.
Lets begin with the first example – geekar, an Augmented Reality-enhanced retail, in the most early-adopter industry I know: geeks. geekar will sell comic books, tabletop roleplaying sourcebooks, board games, trading card games, manga, anime, computer games and so on.
Is it really necessary to invest a lot of money to build something? I guess it depends a lot on the product. My start-up is based on a web app, and I don’t need to hire anybody at all, I do it all by myself, so I think I will only need to spend money on Google App Engine resources, which is not very expensive. I am being too optimistic? What do you think?
In your specific case as you tell it, it indeed sounds like bootstrapping is the way to go. But we have almost no information.
Just ask yourself these questions, for each atlernative (bootstrapping, getting angel-size investment, getting bigger angel-size investment and hiring help, getting VC-size investment):
What are my chances of success?
How much profit will the company generate*?
How much profit will I earn?
How will my lifestyle be before I become very profitable?
How much fun will it be?
* It’s not trivial that this has different answers for different initial investments, but if you think about it you’ll probably agree.
Make a table, think of the answers. They are different for every business and every founder. Who knows, you might even decide to get an investment and hire someone just because you feel lonely working alone, even though you can withstand spartan living conditions and have a slight preference for 100% of profit to 50%.
