Title: [asterisk-dev] Suggestion on Packet Loss Concealment Algorithm

Hi all,

        The current PLC algorithm uses only one pitch period, and therefore behaves bad during burst lost (Beeps in background),

I have prolonged the pitch period under burst loss situation and tested it using a small utility of ITU STL2005. As for the music files

(which were produced using VLC's file output module), the modified plc can handle 50% and 50ms long loss, although it might be that

the music wave doesn't vary very fast, i think the modification still improve the performance very much.

        The attachment is the rar of the modified files, very little change <<asteriskplc.rar>> .

Sincerely,
Colin
