I am currently developing an app that will contain large amounts of audio, around 60-120 minutes. Most voice audio files. My question is really what is the best way to go about storing them. For example, one single large file, separate audio files, download-as-needed cache files.
Any suggestions on file format?
These are the audio formats decoded by iPhone hardware that should take the least power to play.
Whether to have the audio distributed with the app or separately would depend on the use. If you could reasonably expect the user to go through the material sequentially, you may want to allow the user to download part by part or stream the audio to let them conserve space on their device, while if the audio is more random access, you’d probably want it all on the device.
