TapeDeck and Capo Updates for the Mac

This week I shipped Capo 2.1.10 and TapeDeck 1.5.2.

Capo 2.1.10 addresses a few major issues that were found in the 2.1.9 update, as well as some longer-standing ones. For instance, the default keyboard shortcuts failed to operate properly and displayed...


Capo 2.1.9

It was an odd coincidence that Capo 2.1.9 was released on the same day as Capo 1.3 for iOS. I submitted both products on the same day, and fully expected the Mac update to take twice as long. I'm glad to see things seem to be improving with Mac App...


Capo 1.3 for iOS

Today I released Capo 1.3 for iOS, and you can buy it now from the link at http://capoapp.com/iphone.html.

Help Wanted

I'm going to level with you: I'm drowning here on my own with four products on my plate and a fast-moving set of platforms to support. I'd rather be focusing on adding features, but lately I am spending too much time on playing catch-up.

So instead...


TapeDeck 1.5

It might appear that I've not done much to the app in a while, but TapeDeck 1.5 represents months of technical debt repayment, plus a few new features.

First off, the new stuff. I added Retina support and improved the quality of YouTube uploads. Now...


#pragma mark CALayer Texture Atlases

Here's a nifty trick I used recently to implement the fast-moving low-overhead time display in Capo. Maybe you can use it somewhere that you might have fast moving digits in your UI.

The naïve implementation of my time display actually involved a...


#pragma mark vDSP (ab)use

Have you ever wished you could memset() with a stride parameter? Are you also using floating-point values?

OK, let me frame this a different way. Suppose you're drawing a waveform on the screen. You'll need to set a list of points, where the X values...


Building the Fast Fourier Transform

I wrote a guest post over at Mike Ash's blog about the Fast Fourier Transform. Check it out if you're interested in learning a bit more about how it works.

I have a lot of potential follow-up post ideas to continue this series on Fourier Transforms...
