Most Chinese movies, for example, do not record sound at the same time they film.

They are wireless and high resolution but don't record sound.

Could a pen that records sound while you write be the key to taking good notes?

Over the course of a year, 600 sounds were assembled and recorded.

Methods, machines, and media have changed much since sound was first recorded.

As a result, they produce a warmer, better recorded sound.

It does not record sound, take pictures, connect to my computer, send e-mail or even make phone calls.
