Dictaphone
From Tardis Wiki, the free Doctor Who reference
A dictaphone was a device which recorded sound.
Jamie McCrimmon was fascinated by gadgets such as Polly's secretarial dictaphone, on which she kept his recordings for many years after their travels. (AUDIO: The Forbidden Time)
In 1969, the Tenth Doctor recorded an alien signal at Mission Control with a dictaphone, and then was arrested. After the Doctor escaped several days later, he used the TARDIS to translate the recording into a visualisation of the sounds so he could communicate with the aliens. (PROSE: Blue Moon)
Ben Anderson, a travel writer, used a dictaphone while sailing on the Neptune. (PROSE: Dateline to Deadline)
