The "Parabolic Microphone Filter" is the main tool for identifying the memories inside the patient's mind. This element, which can be equipped via the "TAB" key, cast an invisible ray parallel to the line of fire, transferring an audio signal from the point where the ray meets any obstacle, to our ear.
The "filter" function of the PMF (automatically activated each time it is equipped) allows you to hear otherwise indistinguishable sounds. Generally, but not necessarily, these sounds are associated with the patient's memories. In the event that a sound coming from a memory, a blinking message"Signal detected" will appear in the lower portion of our Inspect-On. The background of this writing has the task of indicating the distance to the nearest memory position.
Red Background - sound coming between 150 and 100 meters **
Yellow Background - sound coming between 100 and 50 meters **
Green Background - sound coming within 50 meters **
A signal was picked up between 100 and 150 meters from the collision point.
With the PMF equipped it is possible to mark the last position of the listening point using the "F" key. A yellow symbol (defined as PMF marker) will then be added to both our map and the compass, making it easier to search for memories.
Using the "F" key, you can mark the last position of the heard sound (marked in Yellow). Probably a memory is nearby!
It was clear early on that unregulated use of PMF led to severe neurological consequences for the patient. To avoid abuses in its use, access to this tool is initially inhibited for Inspectors who are about to enter the mission for the first time. The PMF is generally stored in a safety cell, accessible only to owners of the appropriate electronic card.
This key is made available only after finding at least one memory and deactivating a beacon. As an additional security measure, the key spawns randomly into the subconscious and it will be up to the inspector to find its location.
<aside> ❗ NB: The PMF is a useful but not essential tool for patient awakening. The awakening process can be completed even without it.

The electronic key reserved for Inspectors.
The safety cell is where the PMFs are stored.
In any case, the use of the PMF is limited to some areas only, the field of action of which is displayed inside the Inspect-On by a white circle. The flashing message "PMF now usable" appears every time you enter this range. The PMF is equipped with a safety system that automatically deactivates the tracking system once outside the permitted areas.
Remember to check the Inspect-On to understand if is safe to use the PMF or not.
The iconic shape of the PMF resembles a large water gun. The two rear ampoules are used to store the tracer gas (in a minimum quantity for 3 missions), while the shape of the truncated-conical barrel serves to limit the listening cone.
