Stripping an M4A down to a raw AAC stream removes the MP4 container for broadcast tools and embedded devices that want bare .aac files. The codec never changes, so the audio comes through bit-for-bit.

Why convert M4A to AAC?
- Supply ADTS streams to HLS packaging and broadcast tooling that ingests raw AAC rather than MP4 files.
- Load prompts onto IVR phone systems and embedded hardware that read .aac but choke on container metadata.
- Satisfy older mobile phones and firmware that list .aac support without full MP4 parsing.
Tip: Audio quality is untouched because nothing is re-encoded — but tags, artwork, and chapters live in the MP4 container and are lost along with it.
