Documentation related to the ISO/IEC 13818-3 standard. The standard for information technology, generic coding of moving pictures, and associated audio information systems.
I would like to know before coding and modifying audio files such as .mp4 files submitted to the iTunes store or other media type’s such as Podcasts, that it applies to Apple’s media standards.
- Or is there a universal pre-processing stage Apple implements when such audio files are submitted to iTunes?
So far I have only found a utility set that allows conversion from .wav files to .mp4 by iTunes. Would be nice to know what these conditions these droplet files and scripts provide, specification-wise.
