Listening to youtube vids voice inversion still seems to still be legible to a degree after encryption, so I'm not sure if this circuit will be good enough, but one thing usefull is the pll carrier extarction circuit, I'm sure I could use that with a 'duino. The former is from the 70's and requires experienced operator adjustments, the latter is a similar circuit but not using fiddly transformers, and it has a nifty pll locked oscillator so the rx oscillator remains in phase with the tx carrier oscillator. The I found this (google translate convert sit to english):

I really need EEG, ECK, EMG, and other detection on the body to associate the assault signals effect.Yup thats what I meant, the rigs have the usual 4 pin mic socket and 3.5mm mono ext speaker sockets, I'd have to implement an external audio amp & speaker but thats no problem.

Unfortunately, I am not detecting all the time when the mind and body assaults happen. As with most the signals I've detected, they seem to be at a low intensity to blend with the environment amplitude dB. I'm thinking from a SODAR/RADAR perspective that this would be the transmission countermeasure for the internal system or boundary for the assaults detected in the incoming environment transmission (with magnitude and direction). Thank you for sharing the inversion information since seems really simple once understood. However, for the time being I am working on other projects related to sound, mind and body assault detection and RDF like noted on. I'd have to perform a more compare and contrast list to determine the differences better. I have to read up on baudline more, though from my cursory review there didn't seem to be as many options available. There are way more features for inputs, processing and outputs.

In regards to an even better spectrum analyzer software compared to baudline, I prefer Spectrum Lab v2.90b: I'm guessing use Oona Räisänen software found at the GitHub site: In the end, we also filter out the unwanted upper sideband. Then the easy descramble comes on with a 1000 Hz error in the selected sampling rate then the easy descramble with an error of 300 Hz and the difficult method with a spot-on carrier frequency and with the upper sideband also audible. We begin with a (fake) scrambled message. ResultsĪnd here's a demo of what it sounds like. This is not a significant improvement it would only require us to do the digital deinversion in two parts with different parameters. Some scramblers, like the PCD4440T, use a split-band inversion where the audio is split into two frequency bands that are then inverted separately and combined. Print $out pack 's', (unpack 's', $sample) * Open my $in, '-|', 'sox scrambled.wav -c 1 -b 16 -e signed -t. # Using SoX for resampling, filtering, encoding/decoding WAV headers # Optional filter - comment out to disable We could improve the audio further by silencing the upper sideband using a lowpass filter. The upper sideband contains the inverted signal, but at such a high frequency it should not significantly impede intelligibility. This will produce two sidebands the lower will be our descrambled audio and will be conveniently at baseband. If resampling is out of the question, we can also multiply the samples with a sine wave oscillating at the seemingly highest scrambled frequency. To make things simpler, the Selectone ST-20B supports eight discrete carrier frequencies, namely 2632, 2718, 2868, 3023, 3196, 3339, 3495, and 3729 Hz, which they claim to be 'the most commonly used inversion formats'. We would need to resample the audio at a rate of 8600 Hz and multiply every other sample by −1 to get intelligible audio. But speech will nevertheless be much more intelligible than in the original scrambled signal.įor example, consider a scrambled piece of audio that seems to have its highest frequency components at 4300 Hz. Slight distortion will still remain, unless the chosen Nyquist frequency perfectly matches the inverted zero frequency of the signal, or the 'inversion carrier' as Selectone calls it. Print $outf pack 's', (unpack 's', $sample) * $sign īecause the whole spectrum is inverted, a sampling rate has to be chosen to (approximately) match the signal bandwidth. # Simply multiply every other sample by -1

# Using SoX for resampling and decoding/encoding WAV headers You should probably try that one instead these old scripts will be preserved here though.

Update 09/2017: I've later released a simple descrambler tool called deinvert.
