Making Musical Apps (book)

Posted on March 17, 2012 by Nuno Correia

O’Reilly has recently released the book “Making Musical Apps – Real-time audio synthesis on Android and iOS”. From the publisher’s website:

“Want to turn your mobile device into a musical instrument? Or equip your game with interactive audio, rather than canned samples? You can do it with Pure Data (Pd), an open source visual programming environment that lets you manipulate digital audio in real time. This concise book shows you how to use Pd—with help from the libpd library—as an easily embeddable and widely portable sound engine.”

I’ve embedded a preview, via Create Digital Music:

Cocos2d for iPhone

Posted on December 23, 2011 by Nuno Correia

From www.cocos2d-iphone.org:
“Cocos2d for iPhone is a framework for building 2D games, demos, and other graphical/interactive applications. It is based on the cocos2d design: it uses the same concepts, but instead of using python it uses objective-c.”

For example, Tiny Tower, iPhone Game of the Year 2011, was built using Cocos2d.

Via Ilari Niitamo, who did his project for the course using Cocos2d.

Putting multitouch in perspective

Posted on November 10, 2011 by Nuno Correia

Microsoft’s recent vision video depicts a future populated by flat touch screens. Bret Victor finds that limiting, and I agree with him. Read more about it here.

Codify for iPad

Posted on October 27, 2011 by Nuno Correia

Codify, an app that brings touch-based programming to the iPad – http://twolivesleft.com/Codify/:

“Codify for iPad lets you create games and simulations — or just about any visual idea you have. Turn your thoughts into interactive creations that make use of iPad features like Multi-Touch and the accelerometer. (…) Codify is built on the Lua programming language. A simple, elegant language that doesn’t rely too much on symbols — a perfect match for iPad.”

Limited, certainly, but might be useful for quick prototyping or teaching (via MacRumors).
