Summary:Block unwanted use of onboard microphone
|
|
|
|
|
Description:
|
2018-07-11 11:56:57 +00:00
|
|
|
Features a '''passive jammer''' technique that engages the microphone thereby
|
|
|
|
|
blocking other apps from using it. But does NOT listen to or record any of the
|
|
|
|
|
audio from the microphone. It uses 0% CPU and no noticeable battery use. However
|
|
|
|
|
is not intended to be left on permanently due to the variety of triggers that
|
|
|
|
|
can cause audio_focus_state changes (VOIP etc).
|
|
|
|
|
|
|
|
|
|
Also features an '''active jammer''' that emits tones constrained to the NUHF
|
|
|
|
|
range of 18 kHz to 24 kHz range. User determined carrier frequency and drift
|
|
|
|
|
limits with rate for random tone emissions depending on the device capabilities.
|
|
|
|
|
For instance 20000 Hz carrier, drift limit 1000 Hz and rate slow - will output
|
|
|
|
|
random frequency between 19 kHz and 21 kHz approximately every second.
|
|
|
|
|
|
|
|
|
|
Audible artifacts are present during the NUHF tones but this may be changed in a
|
|
|
|
|
future release. Experimental white noise output may not be very effective at
|
|
|
|
|
blocking and is a somewhat annoying sound. The device speaker output may not
|
|
|
|
|
have enough amplitude to block unwanted NUHF signals - testing will determine.
