Audiophile is an achievement in Halo 3: ODST and Halo: The Master Chief Collection. It is awarded to players when they find and access the thirtieth and final audio log in the campaign. In order to do so, they must find all 29 audio logs scattered across Mombasa Streets, then follow the Unidentified NMPD officer into Dr. Daniel Endesha's frozen lab on Data Hive, where they will find the final audio log.
In the original game it worth 75 gamerpoints and is represented by a gray square with Audio lines going across it, with 100% written in the lower-right corner, and a picture of the Superintendent looking happy. In the Master Chief Collection it is only worth 10 gamerpoints, and is represented by a sequence of images from Sadie's Story.
A map labeling the locations of each audio log, save the 30th, which is earned in Data Hive.
