Recording on iPod Video

[Outland]

From what I understand, the iPod Video has a line-in record set of pins on the dock connector. Rockbox can then use those pins to record a line-level stereo signal with one of the 3rd party adapters like the MicroMemo.

What I don't understand is why those pins are there in the first place. No Apple accessory provided a line-in jack as far as I know, and the iPod was never advertised as a recorder. Why are they there?

It's for the voice recorder feature: https://everymac.com/systems/apple/ipod/ipod-faq/ipod-voice-recorders-microphones-remote-controls.html

You could buy accessories that would plug into the dock line in.
