The game features 101 audio logs. Some logs are acquired automatically by doing side missions and Investigations like scanning QR Codes, finding weapon crates, completing ctOS breaches, locating Missing Persons, etc. Some logs can be retrieved by Hacking the computers inside all of Aiden's hideouts while the others can be found during specific campaign missions.
Collecting all audio logs won't unlock any trophies or additional rewards but will count towards 100% game completion.

I am unable to find the last Charlotte Gardener audio log as well. I've done all of the ctOS breaches, and I think I have done everything in the game that would give you an audio log.
I am missing #6 and #7 of Malcolm Deodato...
Can't find Charlotte Gardner audio log #3, and the other two had nothing to do with cTos breaches, so whoever wrote this 'guide' is a moron.
I am missing #6 and 7 of Deodato. Any help?
There are 11 Angela Balik audio logs and not 8 as stated.
