Best sound format for mobile audio
Hi,
I am currently working on a new project for iOS and Android, which involves playing a rather long audio session (around 25 minutes). Since the audio files will be downloaded by the user to the Cache directory, I don't want them to be too big. I tested both MP3 and M4A (AAC) formats, and I must admit that AAC is really of much better quality, for a file two times smaller!
But I saw that the AAC format had to be streamed, and that people had various results on iOS (didn't find yet a successful example of this technique working for someone on iOS). So here are my constraints:
- best quality/size ratio
- being able to play the sound while the app is deactivated (i.e. I need background playing possibilty)
- being able to have controls like volume, seeking, and other typical player UI.
Any suggestions about the format I could use? Or is MP3 still a winner regarding simplicity and available features?
Thank you for your help!
Frédéric
