The app is called Vocal Shapes and is a visualizer for monophonic audio signals such as your voice or a musical instrument. Here is a quick demo video:
Here is a breakdown of how the hours were spent:
|Audio Signal Processing||2 hours|
|OpenGL graphics programming & design||4 hours|
|Splash Screen Artwork & Animation||3 hours|
|Fine tuning of processing & graphics||3 hours|
|App Store Submission||3 hours|
|Promo Song & video||3 hours|
|This blog post & product web page||1 hour|
So, 2 hours remain, which I will probably spend making another nice demo video. Lessons I have learned so far:
- Simple apps require dramatically less development time
- Simple apps are more fun to develop
- Even the simplest apps apparently get downloaded by some people
NOW GO TO THE APP STORE AND BUY THE THING FOR $0.99!
Note: this app is no longer available, I haven’t had the time to redo it for newer phones. If I were to resurrect this, it would probably be as a web page, using WebGL.
