The APF-D Processor (Audio Playback Filter) is a real time recorder that operates continuously during your ghost or spirit box session that allows you to analyze the session by:
* Display the audio spectrum
* Pause and resume your Spirit Box session without losing any session and response data.
* Rewind your responses using the Playback feature in 10 second Intervals. You can rewind as far back as you'd like.
* Amplify audio
* Listen to responses slower using the adjustable speed control to make deciphering easier. If you hear something, you can rewind the response, and then slowly decrease the speed in 5% increments until you can hear the response more clearly.
* Our Adjustable Noise Filter (ANC) removes as much or as little noise as you want from the sweep session.
* Adjustable high pass filter will allow only higher frequencies to pass through. It elevates the responses that sound muffled or have too much base.
* Provides a real time Audio spectrum of sounds and voice artifacts.
* Comes with a Bluetooth Tx and Rx.
* Has a Built-In Speaker or can be used with an external speaker.
* Designed to be used with any Spirit Box or Audio Recording device with 3.5mm audio output
