Speex dev - Aug 2004 - Packet loss concealment ??

Hi,

I would like to know which method uses Speex to conceal the loss of packets.
I've reviewed the code and haven't found anything.

Thanks in advance.

Iago Soto.

I am a student and working on Speech Coding and Speex.
I just want to know where to get the document
describing subvector quantization of innovation. Is
there any document which can help me know how C code
works or any paper exactly explainin the idea?

Hi,

Look at the nb_decode_lost function in nb_celp.c. The main idea for
packet loss concealment in Speex is to repeat the excitation and pitch
of the previous frame (roughly) using more "conservative" LSPs and a
pitch gain < 1.
