- Testvectors to verify correct execution of G.729 ANSI-C software
- Version 3.3
- This directory contains testvectors to validate the correct execution
- of the G.729 ANSI-C software (version 3.3). NOTE that these vectors
- are not part of a validation procedure. It is very difficult to design
- an exhaustive set of test vectors. Hence passing these vectors should
- be viewed as a minimum requirement, and is not a guarantee that the
- implementation is correct for every possible input signal.
- Format: all files contain 16 bit sampled data using the Intel (PC)
- format.
- *.in - input files
- *.bit - bit stream files
- *.out - output files
- and were obtained using the following commands
- coder file.in file.bit
- decoder file.bit file.pst
- Note that for some files only the *.bit and *.pst are available.
- The testvectors were designed to provide as much coverage as possible
- in terms of parameters and algorithm. Below we indicate what parts of
- the algorithms are excercised. Note that none of these sequences
- provides an exhaustive coverage.
- algthm - conditional parts of the algorithm
- erasure - frame erasure recovery
- fixed - fixed codebook search
- lsp - lsp quantization
- overflow - overflow detection in synthesizer
- parity - parity check
- pitch - pitch search
- speech - generic speech file
- tame - taming procedure
