 The same functionality is available in the form of a library. See include/lpcnet.h for the API.
 
+Packet loss concealment can be tested with:
+```
+./lpcnet_demo -plc_file noncausal_dc error_pattern.txt input.pcm output.pcm
+```
+
+where error_pattern.txt is a text file with one entry per 20-ms packet, with 1 meaning "packet lost" and 0 meaning "packet not lost".
+noncausal_dc is the non-causal (5-ms look-ahead) with special handling for DC offsets. It's also possible to use "noncausal", "causal",
+or "causal_dc".

 # Training a new model
 
 This codebase is also meant for research and it is possible to train new models. These are the steps to do that:
