The Microcone from Dev Audio allows the simultaneous recording of up to six separate audio tracks in a meeting situation.
The Microcone is a multi-directional microphone with six faces, and each face gives a separate audio recording. It provides six, independently controllable pickups for different group members.
It is paired with a Mac application called Microcone recorder, which records each person into their own track, and shows each of those tracks on a timeline. You can annotate the timeline with action points and bookmarks. Finally the audio tracks can be uploaded to Nuance for automatic transcription.
