iPads are widely used for listening to recordings, podcasts, and voice memos, but Apple's tablet handles AMR files inconsistently across its built-in apps. The iPad Audio preset converts AMR recordings into AAC wrapped in an M4A container — the exact format that iPadOS treats as a first-class citizen in Files, Music, and every audio app on the App Store.
While iPadOS can technically decode AMR through the Core Audio framework, the Files app may not preview it, AirDrop may not recognize it, and third-party apps often skip over .amr files. Converting to the iPad-optimized AAC/M4A format guarantees smooth playback, lock-screen controls, AirPlay streaming, and correct display in the Music library with proper metadata.
The conversion decodes AMR to PCM and re-encodes using Apple-compatible AAC-LC at 64 kbps mono (for voice) or 128 kbps stereo, enclosed in an M4A container with Apple-standard metadata atoms. The output conforms to iPadOS media framework expectations for seamless integration.
AAC-LC at 64 kbps is transparent for narrow-band speech. The iPad's audio hardware and DSP actually enhances playback with bass correction, so converted files often sound better on iPad speakers than the raw AMR played on the original phone.
