I'm working on an app that will play several audio files. I have gotten that to work, having no trouble. But I'm not sure what file format to use. Right now I am using .wav and one .mp3. Is there a file type that is recommended? I don't know how the app is packaged for the App Store; should the audio be compressed or uncompressed?
Thank you!
It depends on what you're trying to accomplish.
Personally, I favor compression unless quality is an issue. Mp3s, while lossy is my preferred default. It's a standard file type, easy to work with, it can be high quality and iPhone/iOS is efficient at decoding.
However, if you need higher quality, AAC or uncompressed can be better. It's also possible for an mp3 to take a fraction of a second before it starts to play due to decoding. That may or may not be an issue if your audio is tied to a UI event.
