RP-CELP Codec
by kévin B 21 Dec '16

21 Dec '16

Hello, Has someone managed to make the rp-celp codec work or found another way to do it. When I use it I have a scrambled-like sound in the wave file. I know I must use tetrapol_rx but I have a hack-rf only and it seems to doesn't work with it. I know my decoded frames are ok because I was able to listen to clear voice when there was the online decoder. Best Regards.

Online decoder audio empty
by kévin B 18 Oct '16

18 Oct '16

Hi everyone, for sometime I realized that the online decoder provide an empty sound. Like if we hear the carrier only but without voice. I can just hear a kind of low breath. I joined my records. I know what I decode is uncrypted. Do you know this problem ? Thanks a lot.

Add a "tetrapol_dump" option
by kévin B 27 May '16

27 May '16

Hi, I'd like to know if it would be possible to add an option for tetrapol_dump. Currently it has : Usage: ./tetrapol_dump [OPTIONS ...] -i <PATH> input file with demodulated bits -b { UHF | VHF } radio band (default is UHF -t { CCH | TCH } select betwen control and traffic channel -d { DOWN | UP } direction, downlink/direct or uplink Would it possible to add an option to sort between "DATA" "VOICE".... It would be like that : -x {DATA | VOICE | ALL} ... It would allow to sort the output. Thank you for your work ! Kevin.

You don't have tetrapol_dump in PATH. Either add it there or use full path. > Scan with scan.hs ? No, just use your favourite SDR tool, e.g. gqrx. > Finally, if i haven't got tetrapol station connected ( TPH 700 or 900 or other ) i can't decode audio. Correct ? Correct. And usually you can't decode even if you have a station, because it's just encrypted. > If i understand, the RP-ACELP codecs will be available later, and it will not be necessary to have external station for decoding the voice ? We hope so.

Re: [Tetrapol-kit] RP-CELP decoder doesn't seem to work

As you can see, there is KEY_TYPE=4 KEY_INDEX=5, so your network uses encryption. We are not able to decode it. The original hardware codec decodes it this way: http://nat.brmlab.cz:8064/tpol/xgm1wspuj5.d/frames.ogg. It is encrypted, so no chance anything hearable will result. > Only a last question: How can I send the json files to the online decoder? You run cat *.json|grep '"type": "VOICE"'| grep -oE '"value": "[0-9a-f]{30}"'| cut -d \" -f 4 | blhexbit | sed -re "s/(.)(.)(.)(.) (.)(.)(.)(.) /\8\7\6\5\4\3\2\1/g" | sed -re "s/^([01]{20})/\1_/g">voice.bits and then paste the voice.bits file (or part of it as it is huge - sane is about 1500 lines a time) to http://nat.brmlab.cz:8064/ That is exactly what I did to get the above .ogg. However there is no point in it unless you see some traffic with KEY_TYPE=0 KEY_INDEX=0 or KEY_TYPE=15 KEY_INDEX=0, as you will get only encrypted gibberish.

Ah, I thought that you use our online decorer at http://nat.brmlab.cz:8064/. If you are using software rp-celp implementation, it is expected that it doesn't work, as the codec is not yet fully implemented.

RP-CELP decoder doesn't seem to work

Hi! I'm testing the latest tetrapol-kit with a TETRAPOL signal (formerly known as SIRDEE here in Spain). I capture well, and decode to JSON, but when I use the rp-celp codec to extract audio, I only get weird sounds. I don't know if I could send you a sample. crushedice2000 +=|at|=+ thatmailofgoogle . com Thanks in advance. Helio. -- Un saludo. Helio.
