I recently wrote a feature looking at the broader concepts of iPhone audio design to tie in 
with my earlier article looking specifically at asset size, “Size Matters“.
Since the launch of the iPhone, apps have been big, especially in the games sector, which has seen some sell like AAA titles. Major developers have added the iPhone to their list of available platforms for existing titles, as well as moved to develop unique titles just for it.
The feature is published exclusively on Gamasutra.com and can be read here.
I hope people find this article useful when producing audio for the iOS devices. Please send any additional thoughts. Enjoy!
