I'm preparing an ibook filled with HTML5 widgets. All of them have audio elements. Apple specifies AAC audio format. Hype indicates mp3, ogg, or wav. What is the proper way to proceed?
You should be fine with just MP3s -- they are fully supported by iBooks. If you need to do bulk conversions, I recommend Miro Video Converter: http://www.mirovideoconverter.com
Thanks Daniel for such a quick reply. It's very helpful. I'm sure Miro is fine, but for batch audio conversions I usually go with Apple Compressor.
