Spectrum Analyzer [005]
I spent the better part of a week working on demodulation - but I haven't produced any sound yet. It's difficult to get straight, concise and understandable information on exactly how to filter and demodulate.
So, I went back to working on the UI. You can

I put AM demodulation on hold for a moment and moved some code around so that I can better support demodulation later. In the new system (there's no point in dwelling on the particulars of the old system), the device read thread passes a newly received block of

My original, ill-conceived notion for drawing a waterfall display was to do a bunch of CGContextFillRect() each drawing a 1x1 rectangle. 1024 pixels wide * 250 pixels tall * redraw-rate = millions of 1x1 rectangles per second. Yeah, that didn't work at all.
So, I made a second internal representation of

I've had current (red line), average (green fill) and max (blue fill) correctly drawing for a while, but it's taken some time to get the scale (in dBm) right. And I'm still not accounting for gain associated with the window function and the fft.

I was asked what I am currently working on. "A spectrum analyzer," I replied. Blank stare. That's not uncommon though so I didn't think anything of it. Then there was a follow-up question: "A spectral man-a-lizer??" It was my turn for the

Not that there is a want of reasons to dislike MySpace, but now they've gone and bought Imeem and promptly shut it down. Thanks for that. When will MySpace die?

Okay, so, there was a New Kids on the Block music video playing at the gym this evening. And not one from the early 90's either. We're talking about a _new_ music video. Scary stuff.
You see, this is what I remember of them (*shudders*):

So, there's a live video feed of some dude's brain being sliced to pieces. Slowly. Note: the dude is dead and the brain is frozen.
