Timed-stream transcoding: how AAC becomes iPad Audio
Converter.now decodes the waveform and channel layout carried by AAC, then writes the codec and container profile used for iPad Audio. Duration can remain identical while compression, channel mapping, frame cadence, metadata, or auxiliary streams change. AAC arrives as coded audio frames without the richer track tables expected from an MP4-family container, so timing and tags are reconstructed from the elementary stream.
Decoded media - Lossy Advanced Audio Coding frames used by many streaming and device workflows. Encoded delivery profile - A preset that converts audio to M4A (AAC), the format iPad's Music and Files apps play back natively without a third-party app.

AAC source facts versus iPad Audio output requirements
What can fail when AAC audio format is interpreted
An AAC elementary stream carries less container metadata than M4A and another lossy encode can soften transients.
What iPad Audio audio format cannot safely promise
Because this preset always outputs standard AAC in M4A rather than Apple Lossless (ALAC), users converting audio for archival or bit-perfect playback in the iPad Music app will get a lossy file regardless of which device preset they pick.
How the iPad Audio writer handles this route
The ipad-audio preset always encodes to M4A (AAC audio) at a fixed bitrate with no per-device profile switching, which works in practice because M4A/AAC is the one audio format every iPad model, from the original 2010 iPad onward, has been able to decode natively.
Acceptance evidence for the converted iPad Audio
Record the AAC evidence before conversion
Listen for speech sibilance and music attacks, then confirm duration and channel layout.
Test the iPad Audio file in its receiving workflow
Transfer the converted M4A file to an iPad via AirDrop or the Files app and confirm it opens and plays in the Music or Files app without a "format not supported" or "cannot play" error.
The delivery decision for this AAC to iPad Audio route
Confirm the receiving player, editor, or publishing service actually names iPad Audio's container and codecs before switching; stay with AAC if extra tracks or original encoding need to survive intact.
What changes between the AAC model and the iPad Audio deliverable
- The source stores lossy Advanced Audio Coding frames used by many streaming and device workflows; the destination stores a preset that converts audio to M4A (AAC), the format iPad's Music and Files apps play back natively without a third-party app. Compare application metadata after that structural change.
- Treat AAC-specific metadata fields as optional in the iPad Audio result until you have actually confirmed they survived.
