TL;DR

Saros has over 150 total collectibles including Audio Logs, Text Logs, and Holo Logs.
Audio Logs are spread across all 8 biomes with counts ranging from 9 to 17 per zone.
Shattered Rise has the most Audio Logs of any biome — 17 in total.
Audio Logs are not required for the Platinum trophy but count toward 100% completion.
They appear as a white glow in the environment and show as icons on the minimap.
Spawns are tied to biome-specific location types rather than fully fixed map positions.
No Audio Logs are missable — all biomes remain accessible after story completion.

Audio Logs are one of the three main collectible types in Saros alongside Text Logs and Holo Logs. Each one gives you more insight into the former colonists of Carcosa, the Echelon expeditions, and the events that led to what Arjun finds when he arrives. The story in Saros is told largely through environmental discovery, and Audio Logs carry a significant chunk of that narrative.

This guide covers how Audio Logs work, how many appear in each biome, where to find them, and how to make sure you do not miss any across your runs. If you are also tracking down Text Logs, our complete Saros Text Logs guide covers those in full.

How Many Audio Logs Are in Saros?

Saros has over 150 collectibles in total across Audio Logs, Text Logs, and Holo Logs combined. Audio Logs are spread across all eight biomes, with each zone holding a different number. The counts per biome range from 9 to 17, with Shattered Rise holding the highest concentration of any single area.

Collecting Audio Logs is tracked in the Databank. It is not required for the Platinum trophy, but if you are aiming for 100% completion, you will need to find all of them. The good news is that no Audio Log is permanently missable. After completing the story, all biomes remain fully accessible and you can return to any area to pick up what you missed.

How Audio Log Spawns Work

Audio Logs in Saros do not have fully fixed positions. The biome layouts are randomised between runs, so a log that appeared in one room on your first visit may be in a different part of the biome on a later run. What stays consistent is the type of location — Audio Logs always appear in side camps, off-route rooms, and specific exploration spots rather than randomly in open corridors.

This means you cannot follow a precise map and mark each log on a specific tile. What you can do is learn the patterns — Audio Logs reward players who check every branching path, enter every side camp, and use the Area Scan before clearing a room. If you move fast through the main route only, you will consistently miss logs in biomes with high counts.

Some Audio Logs are also gated behind Permanent Equipment. If a route is blocked when you first visit a biome, the log behind it is not gone. Come back once story progression has unlocked the relevant ability. For more on traversal abilities and when they unlock, see our guide on how to unlock the Grapple in Saros and our guide on how to unlock Eclipse Threads.

How to Spot Audio Logs

Audio Logs glow white in the environment, the same as Text Logs and Holo Logs. When you get close enough, a pop-up identifies exactly what type of collectible you are looking at before you pick it up. They are placed in spots that stand out visually from the rest of the environment — look for the white light rather than scanning every wall.

The minimap is the most reliable tool for finding logs efficiently. A small icon appears on the minimap directly over any collectible in the surrounding area. Keep the minimap visible at all times, especially when entering new rooms or before clearing enemies and moving on.

The Area Scan (D-pad down) sends out a sonar pulse that highlights nearby collectibles and interactables. Use it every time a path branches or a room feels sparse. It takes one second and confirms whether something is worth checking before you move on. This habit alone prevents most missed logs across a full run.

You can also track your progress per biome by opening Primary and checking the World Dial. Selecting any biome shows how many collectibles and materials you have found within it, which tells you how close you are to completion without needing to memorise individual counts.

Audio Logs by Biome – Count Reference

Shattered Rise — 17 Audio Logs

Shattered Rise has the highest Audio Log count of any biome in the game at 17. This is the opening zone, which makes it the most accessible area for lore hunting. The mountainous rocky terrain has multiple side paths and camps that branch off the main route, and most of these hold at least one collectible.

Because Permanent Equipment restrictions are minimal this early in the game, most of these 17 logs are reachable on a standard run without needing to return later. Shattered Rise is the best biome to practice thorough exploration habits before the later zones introduce more gated content.

Tarn’s Camp is one of the notable side rooms in Shattered Rise that consistently holds Audio Logs or Text Logs. To enter it, you typically need to use your melee and your shield. Inside you will find tents, gear, and rectangular containers alongside the logs. Any side room that requires an extra step to enter is almost always worth checking in this biome.

Ancient Depths — 14 Audio Logs

Ancient Depths holds 14 Audio Logs, tied with Yellow Shore for the second-highest count in the game. This subterranean biome is built around tunnels and glowing caverns with rising platform mechanisms. The vertical layout means logs can appear at different height levels, not just on the ground floor of each room.

One important note for Ancient Depths: some side paths are only accessible when the Eclipse is active. If you arrive at the Vault without having triggered the Eclipse, one of the two main branching paths will be locked behind an Eclipse barrier, and any logs on that side of the biome will be unreachable until you activate it. Always trigger the Eclipse before heading to the Vault if you want full access.

Jump Network Pads unlock in Ancient Depths, which also opens up elevated areas that were previously out of reach in this biome and earlier ones. Our guide on how to unlock Jump Network Pads in Saros explains how to get that ability.

Shattered Descent — 14 Audio Logs

Shattered Descent is the shortest biome in the game but still holds 14 Audio Logs — a surprisingly high count given its compact size. This vertical, gap-heavy zone is where the Grapple unlocks, which immediately opens up previously unreachable platforms and side areas not just here but retroactively in earlier biomes too.

Because the biome is short in terms of main-path length, many of these 14 logs are tucked into side areas that require deliberate exploration rather than stumbling across them on the direct route. Shattered Descent is also a gateway zone that connects to multiple other areas once you have the right movement tools, so it rewards multiple return visits.

Shattered Descent is also the biome most commonly recommended for trophy farming due to its short layout and Rhabdom’s single health bar. If you are grinding runs here anyway, use each visit to chip away at the log count. Our complete Saros biomes guide has a full breakdown of what each zone contains.

Blighted Marsh — 10 Audio Logs

Blighted Marsh holds 10 Audio Logs. The swamp biome is the most hazardous environment for exploration. Proximity traps chain-explode if you move carelessly, and the poisoned waterways erupt periodically to punish players who stand still in the wrong spot.

Because the environmental hazards demand so much attention, it is easy to rush through the Blighted Marsh without checking side areas. The Audio Logs here are placed in spots that require the same deliberate off-path exploration as every other biome, but the constant threat from the environment adds pressure to keep moving. Resist that pressure. Clear traps before exploring side rooms and use the Area Scan frequently.

Reaching the boss Legion also requires restoring power to both terminals before the elevator activates. Exploring both branching paths to restore power naturally covers a large portion of the biome, which is useful for log hunting. Do not skip either path on the assumption that one is optional — both have collectibles and both are needed to reach the boss. Acolyte’s Haven is also accessible through a hidden route within Blighted Marsh, so thorough exploration here pays off in two directions.

Desecrated Fortress — 11 Audio Logs

Desecrated Fortress holds 11 Audio Logs. This once-grand citadel is now a ruin of falling debris and shattered stonework, spread across multiple vertical levels. The biome introduces Honorarium Sigils as a separate collectible and unlocks Eclipse Threads as a permanent ability, which lets Arjun traverse beams of light to reach upper levels that are completely inaccessible on a first visit.

This means some of the 11 Audio Logs in Desecrated Fortress will be locked behind Eclipse Threads on your first run through. Do not assume you have found everything until you have come back with this ability active. For more on that, see our guide on how to unlock Eclipse Threads in Saros. And for the other collectibles in this biome, our guide to Honorarium Sigils in the Desecrated Fortress is worth reading before you explore.

Acolyte’s Haven — 9 Audio Logs

Acolyte’s Haven holds 9 Audio Logs, the lowest biome count in the game. This dock-and-wharf zone is built around floating platforms and combat-grapple navigation. The grapple points here only activate when Arjun shoots them, turning movement through the zone into an active traversal puzzle. Logs are placed across platforms at various heights throughout the biome.

The floating platform layout means some Audio Logs are harder to spot visually until you have moved to the right elevation to see them. Always use the Area Scan when crossing between platform clusters. If a log icon appears on the minimap in a direction that looks like open air, there is usually a platform or grapple point that leads to it.

Acolyte’s Haven is accessible through a hidden route within Blighted Marsh. Make sure you have explored Blighted Marsh thoroughly before assuming you cannot reach this biome. Our guide on how to unlock the Grapple in Saros is essential preparation for this zone.

Cathedral — 13 Audio Logs

Cathedral holds 13 Audio Logs, making it one of the denser zones for lore content despite its unusual structure. This biome functions as a temple with its own gravity mechanics. Arjun can reverse the alignment and stand on the roof after activating a specific mechanism, which opens up an entirely different set of rooms and paths that do not exist in normal orientation.

This gravity-flip mechanic means logs can appear on what is effectively the ceiling of certain rooms when viewed from the standard orientation. Make sure you explore both the normal and inverted versions of each area. A room that looks fully cleared from one perspective may have collectibles accessible only from the other.

Reaching the boss Priestess requires exploring two side paths and making the bell fall before the endless staircase to the boss arena becomes accessible. Those side paths also contain a secret optional area. Both the paths and the optional area are likely sources for Audio Logs in this biome. Do not skip them.

Yellow Shore — 14 Audio Logs

Yellow Shore holds 14 Audio Logs, tying Ancient Depths for the second-highest count in the game. This is the final biome and where Arjun’s last permanent ability, Blazing Strike, unlocks. Despite being the final act zone, Yellow Shore is not a biome to rush through even when you are close to the ending.

The Halcyon situation in Yellow Shore is unique — there is no tracker and the resource comes from Alpha enemies and containers rather than fixed collectible spots. Audio Logs follow the same biome-wide spawn logic as other zones, placed in side areas and off-route rooms throughout the map. The Area Scan is especially valuable here given that this is a zone many players are eager to push through quickly.

Once King is defeated, the story concludes. If you are working toward the true ending or the Epilogue, you will be returning to Yellow Shore regardless. Use those return visits to cover any Audio Logs you missed during the first clear. For more on that, see our guide on how to unlock the true ending in Saros.

Tips for Finding All Audio Logs in Saros

Check Side Camps and Off-Route Rooms First

Almost every Audio Log in the game is in a side camp, a branching side path, or a room that requires an extra step to enter. If you are only following the gold-flag main route marker, you will miss the majority of logs in every biome. Make it a habit to check every path that branches off the main route before clearing a room and moving on.

Use Area Scan at Every Branch

Press D-pad down whenever you reach a fork or a room that looks empty. Area Scan takes one second and tells you immediately whether something is nearby. It is the fastest confirmation tool in the game for collectibles and saves far more time than backtracking after missing something.

Return with New Abilities

Several Audio Logs across multiple biomes are gated behind Permanent Equipment that you will not have on your first visit. Do not stress about 100% on a first pass. After each major story milestone, return to earlier biomes with your new abilities and check the areas you could not reach before. The World Dial in Primary shows exactly how many collectibles remain per biome, which makes targeting specific return visits straightforward.

Trigger the Eclipse Before Exploring

In biomes like Ancient Depths, certain side paths are only accessible when the Eclipse is active. Triggering the Eclipse at the first available opportunity ensures no areas are locked off during your exploration pass. Logs behind Eclipse barriers cannot be reached without it, and you will not always be prompted to activate it before reaching those areas.

Do Not Rely on a Single Run Per Biome

Saros is designed around repeated runs. Trying to find every Audio Log in a single pass through a biome is both stressful and often impossible given ability gates. The game rewards players who come back. Each return visit is a chance to cover more ground, and the Armor Matrix upgrades you accumulate make biomes feel shorter and faster on later runs anyway. See our guide on which Armor Matrix upgrades to unlock first to make sure your runs are as efficient as possible.

Do Audio Logs Affect Trophies?

Audio Logs are not directly tied to any trophy requirement. You can earn the Platinum in Saros without collecting a single Audio Log. However, because they contribute to 100% biome completion tracked in the Databank and through the World Dial, they are part of the full completion goal for players hunting everything in the game.

If you are working toward the Platinum and want to know exactly what is and is not required, our complete Saros trophy guide breaks down every trophy and how to unlock each one.
