Om konvertering från AAC till iPhone Audio
The iPhone has used AAC as its primary audio codec since the original 2007 model. The iPhone Audio preset ensures your AAC files are encoded with parameters that match the iPhone's hardware audio decoder exactly — AAC-LC profile at 44.1 kHz in an M4A container. This eliminates edge-case playback failures and maximizes battery efficiency during audio playback.
Varför konvertera AAC till iPhone Audio?
Some AAC files encoded with HE-AACv2, unusual sample rates, or non-M4A containers (like raw ADTS streams or MKV) can cause stuttering, metadata display issues, or software-fallback decoding on iPhone. The iPhone Audio preset normalizes everything to the codec profile Apple optimized the A-series chip's audio DSP for, ensuring native hardware decoding on every iPhone model from the 3G onwards.
