bob avwiseav at gmail.comHi, Sylvain I use your code to decode the AMR in my network, but have no positive result.I have some questions. 1.when I have decode the TCH, and ready write to file, how to set the last argument of the function. length = osmo_ubit2pbit_ext(voice, 0, EFRAMR, 0, 8 + gsm690_12_2_len, 0/1);is it 0 or 1? I use your burst_id branch. 2.are you test your code relate to TCH AMR? have you ever succeed to listen the voice coded by AMR, in your clarifications about 27C3 GSM Sniff Talk, I find you hadn`t completed the AMR decode.you said:" - ... But since I'd like it to support AMR and viterbi soft output before that happens, it could take some time." how about your current process? 3.in your SDCCH sniffer demo, you use snr of the channel to decide a over of a channel, but in the speech of amr, because of DTX, it can not be used, how to settle the problem because I can`t implement the full stack. Look forwarding to communicate with you！ -- View this message in context: http://baseband-devel.722152.n3.nabble.com/is-the-Viterbi-decode-for-the-AFS-provided-by-Sylvain-right-tp4025236p4025238.html Sent from the baseband-devel mailing list archive at Nabble.com.
