Bit ranking in voice frame
by Xilokar 08 Jan '18

08 Jan '18

Hi, I was wondering how the bit positions in voice frames were found (I am talking of voice_frame.py in rp-celp repo) I can not find the info in PAS 0001-7: Version 1.0.3 (so much for a specification...) I am trying to decode Q & ph for each subframe in order to feed the excitation signal in the filters, but there seems to be some incoherency either with my own received frames (that I was not able to test) or with the voice_tones sample from the transmit repo. Regards, Xilokar

tetrapol dump not found and RPCELP question
by atariman＠laposte.net 10 Oct '17

Hello, i'm correctly installed the files, fréquencies found with RTL-SDR are ok when i launch ./tetrapol_detector.sh and in the TMP Folder i fond JSON files , LOG Files et BITS files but when i open a log file i read : ./tetrapol_detector.sh: 53: ./tetrapol_detector.sh: ../build/apps/tetrapol_dump: not found i don't found the tetrapol_dump file. What is the problem ? I think you'll write a better documentation. And my second question (i you can resolve my missing tetrapol_dump file) is how to use and install the codec RPCELP, and what are the type of files i must using with it ? Thank you.
