Description General Information Extended Information
 
The APF-D Processor is a unique device designed to to be used with any Spirit Box or Audio Recording device with 3.5mm Audio Output. The APF-D allows you to:
* Amplify Audio
* Display The Audio Spectrum
* Pause and Resume Your Spirit Box Session without losing any Response Data
* Playback Feature allows you to Rewind your Responses in 10 second Intervals. You can rewind as far back as you like.
* Adjustable Speed Control allows you to listen to Responses Slower to make deciphering easier. So, 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.
* Adjustable Noise Reduction allows you to remove unwanted sweep sounds from your session.
* Adjustable High Pass Filter allows only higher frequencies to pass through

IMPORTANT: Tips when using the APF-D Processor.

It's important to understand that the APF-D is constantly storing data to memory. If you Start/Stop, Rewind, etc. all the sweep data adds up in the Buffer memory, and this can delay the time it takes for the noise filter setting change to take affect. As such, you must either wait (typically 15-25sec) for the Buffer memory to catch up to the Noise Filter change, or reset the APF device to clear the memory backlog. When I adjust the Noise Filter, I always Reset the APF device by pressing S2+S3 simultaneously to clear the buffer memory. Then my first step is to adjust the Noise filter because this will allow the Noise filter changes to take affect quickly with only minor delays. Once you get into the right Noise filter zone, you can "tweak" the SB7 +/- Volume adjustment to increase or decrease the noise through the filter or adjust the Noise by using the APF-D buttons. Also realize that there are 3 ways to adjust the APF-D Volume. The P-SB7, The APF-D and the outer ring on the speaker. The APF-D volume control will also increase and decrease the audio spectrum gain on the display. Note: the SB7 sweep must be stopped to adjust the SB7 volume.

1.Turn the P-SB7T volume to 19-21
2
. Start sweeping
3. Turn the Noise filter immediately to 20.0 to 22.0.
4. Tweak the SB7 volume and APF Noise filter buttons to get the desired results. But be sure to wait 10-20 seconds or so for noise filter to take affect if you do not rest the APF.
5. Be sure your cell phone Bluetooth is OFF to prevent connectivity issues.

5 of 5 APF-D Processor August 3, 2021
Reviewer: Barry Hayden from Warsaw, IN United States  
All of Gary's devices have a proven track record of capturing evidence and the APF-D is no exception. Being able to review evidence as it is captured gives you the ability to refocus or direct your investigation in a particular direction that having to wait on getting home and reviewing evidence does not allow.

I use this device and it has become one of the main tools that I deploy on my investigations. I get great evidence and I'm sure you will too.

Thank you Gary for another great tool.
