Audio logs

Audio logs are auditory information found throughout the Heleus Cluster.

Overview
Audio logs can be found on datapads, consoles and terminals, devices, and other objects.

Because this information is only transmitted in an auditory fashion, if closed captioning is turned off, this information can only be heard. There is no transcription of the information to read or review such as a datapad or a terminal entry. It should be noted that some audio logs can only be listened to one time and then the option to play is gone. Other audio logs can be listened to any number of times.
 * Some audio logs have limited availability and can be lost, such as those present on Habitat 7 during Planetside.
 * Some audio logs are part of specific missions, such as the Task: What He Would Have Wanted series and only appear when the mission is acquired.
 * Some audio logs change content depending upon when they are listened to such as Dissension in the Ranks.
 * Some audio logs are just left lying around where anyone can listen to them, such as the Dead Exile audio logs in the Haarfel region on Kadara.
 * Some audio logs trigger missions such as the one for Old Skinner.

Each section gives details on the specific requirements and/or any findings about the audio log in question.

Blackrock Tande
These three audio logs play in a specific order that is always the same no matter which of the audio logs is played first. The final building location will be empty before the mission Dissension in the Ranks has been acquired. If Dissension in the Ranks is saved until after the Archon is defeated, the three audio logs will change content and the console will display a pre-recorded message.

Cave, North of Prodromos
The first transcription is before SAM has an adequate base for translation. This would normally happen if you go to this location before you have the mission Dissension in the Ranks. If you listen to the log before translation is possible, SAM will comment that he is "adding to language database".

Southern Monolith
The first transcription is from the first hearing of the audio log, before SAM has an adequate base for translation. If Ryder returns later in the game, the second log is when SAM can translate the message.

Task: What He Would Have Wanted
These five audio logs play in a specific order that is always the same no matter which of the beacons is placed first.

Ryder's Room
These three audio logs play in a specific order that is always the same no matter which of the datapads is interacted with first. Once a datapad has been listened to, the audio log that plays is fixed to that datapad. Also, they aren't available until you've listened to the General Log/Asari Archaeologist branch of entries on the Archive System and SAM adds Dr. T'Soni's notes to the datapads.

A Trail of Hope
There are multiple phrases spoken by the Kett Holographic Recording. The phrases vary and will be spoken when approaching the holo. Eventually, the holo sort of breaks down and repeats "I am Archon" a lot. The Kett Holographic Device is fixed and the message does not change.

Kett Facility
There are three audio logs on datapads that display as terminal entries. The titles of the audio logs are fixed and the order of discovery is fixed, but they are not linked—it doesn't matter which audio log you activate first, you'll hear the first audio log.
