1. I don't think OneNote (WP8) capable of doing note taking & voice recording in parallel.
Had tried before but once voice recording function activated, I couldn't taking note.


2. Is there any similar apps line Android's Sync Voice Note

"Sync Voice Note combines the functionality of memo pad and audio recorder to enable user to jot notes with synchronized audio recordings. Sync Voice Note saves you tremendous amount of time to search audio recordings to match with your own notes, and vice versa. Watch the corresponding line being highlighted during playback can be a great help for you to recall the content in which they were taken.

With the power and convenience of your Android phone, Sync Voice Note can be an unprecedented tool for your meetings, interviews, conferences, lectures and a lot more."

There is SyncNote. It says you can voice record in your notes, though it doesn't mention if it will do it in parallel. SyncNote (Free) | Windows Phone Apps+Games Store (United States)
