Audio Tips for iPhone Development

July 21, 2010

Coming up on today’s epsiode:

Audio production techniques for iPhone Application Development. Today we’re going to take a look at audio production workflows I use for iPhone development.

Developing audio assets for the iPhone sounds easy enough, but the real challenge is how you’ll need to optimize for file size.

Optimize File Size

When your working on audio for an iPhone application, it’s best practice to keep your file size as low as you can. Here are some settings I’ve found that keep your file relatively low, without too much quality loss.

Export Audio from DAW for the iPhone.

In your DAW, export your audio at a Sample Rate of 22050, with a file format of AIFF, and a resolution of 16bit. Using this setting should keep your file size small, and your quality at a medium.

Using Folders and Markers in Logic for organization.

When working on a project with multiple parts, a great way to group them is to pack them into a folder, and export them individually. To create a Folder in Logic, select your Regions from the Arrangement Window, goto the Region Menu, and then select Folder > Pack Folder.

Now you can double click to enter the folder, create a loop cycle and if you click and drag down, you’ll create a marker. Using Markers are a great way to keep your project organized. Now we can Bounce it out.

Testing your audio translation on iPhone.

Alright so once you get your audio files on your iphone, you definitely want to spend a lot of time testing your audio translation. Most of the time you’ll find yourself going back and editing your levels. some things are hard to hear on the iphone speaker, like low bass sounds. so listen carefully, and make sure to have fun.
