iLBC Utilities

The following package can be used to verify that your compiled iLBC code works correctly.

Included are:

iLBC_test.txt -- Test script which can be used to produce the .BIT and .OUT files
iLBC_test.exe -- Reference executable created from the code in draft-ietf-avt-ilbc-codec-05.txt
iLBC.INP -- Input speech file
*.chn -- Channel files
*.BIT -- Output bit-stream from the encoder
*.OUT -- Output speech from the decoder

Note that the iLBC code in draft-ietf-avt-ilbc-codec-05.txt is a floating point implementation. Due to differences in compilers and optimization settings your output is likely to differ slightly from the output in the package. Generally the .BIT files are bit-exact while the .OUT files might differ +/-1 for some of the samples, but larger differences might be present in some rare occasions. Keep this in mind when doing the verification.
