There are a total of 129 audio guides in the game and you only need 100 to unlock the achievement. Be aware, unlike the first game, YOU CANNOT return to older locations as you advance from area to area, therefore, if you miss too many, this will become missable.

Here is a great video following the remaster. This includes the weapon upgrade station as well.
