==============================================
|

ITU-T Recommendation G.722.1 (05/2005)
|
||||
C-Source Code and Test Vectors
|
||||
Release 2.1
|
||||
==============================================
|
||||
|
||||
This software package contains the 16/32-bit fixed-point C source code
|
||||
for the encoder and decoder of ITU-T Recommendation G.722.1 including
|
||||
its Annex C.
|
||||
|
||||
The software implements both the 7 kHz mode of G.722.1 and the 14 kHz
|
||||
mode of Annex C/G.722.1.
|
||||
|
||||
This version uses the basic operators provided by the ITU-T Software
|
||||
Tool Library (STL2000) in ITU-T Recommendation G.191 (Ver. 1.0).
|
||||
|
||||
This software has been repackaged for republication with G.722.1
|
||||
(2005) Cor.1 (2008-05), which corrected defects in the floating point
|
||||
specification of G.722.1. For consistency, the release number has been
|
||||
changed from 2.0 to 2.1, but the actual C code has not been changed,
|
||||
and is identical to that of G.722.1 (2005).

Software Notes for ITU-T Recommendation G.722.1 Annex B Test Vectors
|
||||
====================================================================
|
||||
|
||||
To run the encoder:
|
||||
|
||||
encode bit-stream-type in-file-name out-file-name bit-rate bandwidth
|
||||
|
||||
|
||||
To run the decoder:
|
||||
|
||||
decode bit-stream-type in-file-name out-file-name bit-rate bandwidth
|
||||
|
||||
|
||||
The variables for the command line are described in the following
|
||||
table.
|
||||
|
||||
|
||||
Variables Comments
|
||||
--------- --------
|
||||
|
||||
bit-stream-type This variable must be set to "1" or "0". If
|
||||
it is "1", then the encoder will output a bit
|
||||
stream in the ITU-T G.192 format. If it is
|
||||
"0" it will output a compacted bit stream as
|
||||
would be typically used in a communications
|
||||
channels.
|
||||
|
||||
in-file-name If running the encoder, then this variable
|
||||
represents the name of the audio input file.
|
||||
The file is assumed to contain samples in a
|
||||
16bit 2's compliment format. If running the
|
||||
decoder, then this variable represents the
|
||||
name of the bit stream file.
|
||||
|
||||
out-file-name If running the encoder, then this variable
|
||||
represents the name of the bit stream output
|
||||
file. If running the decoder this file
|
||||
represents the audio output samples in a
|
||||
16bit 2's compliment format.
|
||||
|
||||
bit-rate This is the channel bit rate of the coder in
|
||||
bits per second. In case of 7kHz audio, use
|
||||
a value of either "24000" or "32000" for
|
||||
24kbit/s and 32kbit/s, respectively. In case
|
||||
of 14kHz audio, use "24000", "32000", or
|
||||
"48000" for 24kbit/s, 32kbit/s, and 48kbit/s,
|
||||
respectively.
|
||||
|
||||
bandwidth This is the audio bandwidth of the coder.
|
||||
Use a value of either "7000" or "14000"
|
||||
for 7kHz audio (G.722.1) and 14kHz audio
|
||||
(G.722.1 Extension), respectively.

||||

* The "Reversed MLT" is an overlapped block transform which uses

* right and a Type IV DST as the block transform. In fact, it is

* equivalent * to reversing the order of the samples, performing

* Purpose: Convert Samples to Reversed MLT (Modulated Lapped Transform)

|

*
|

* The "Reversed MLT" is an overlapped block transform which uses

* even symmetry * on the left, odd symmetry on the right and a

* Type IV DCT as the block transform. * It is thus similar to a
|
||||
* MLT which uses odd symmetry on the left, even symmetry * on the
|
||||
* right and a Type IV DST as the block transform. In fact, it is
|
||||
* equivalent * to reversing the order of the samples, performing
|
||||
* an MLT and then negating all * the even-numbered coefficients.

SOFTWARE NOTES FOR ITU-T RECOMMENDATION G.722.1 FIXED POINT TEST VECTORS
|
||||
========================================================================
|
||||
|
||||
The test vectors in this directory consist of input and output signals
|
||||
(vectors) to the encoder and decoder. Each input vector provided has
|
||||
a corresponding output vector. Any implementation of G.722.1 using an
|
||||
input vector should be able to produce a bit exact output when
|
||||
compared to the corresponding output vector.
|
||||
|
||||
These test vectors have been taken from the 1999 version of the fixed
|
||||
point C code and have been shown to work properly with the 05/2005
|
||||
version of the fixed point C code.
|
||||
|
||||
|
||||
Warning: Successfully passing the test vectors does not guarantee full
|
||||
compliance with this recommendation. This is because the
|
||||
test vectors do not exercise every state and line of the
|
||||
code.
|
||||
|
||||
|
||||
The following table describes the purpose of each test vector file
|
||||
provided.
|
||||
|
||||

||||

|
||||
|
||||
|
||||
|
||||
Note. All test vector byte ordering is in a PC DOS format found on IBM
|
||||
compatible PCs.
|
||||
|
||||
|
||||
|
||||
As an example, to test the encoder at 24000 bit/s you may type the
|
||||
following command line:
|
||||
|
||||
encode 0 G722_1_enc_in.pcm output_file 24000
|
||||
|
||||
and compare the "output_file" against the vector
|
||||
"g722_1_enc_out_24000.pak". It should be indentical.
|
||||
|
||||
|
||||
Similarly, to test the decoder at 24000 bit/s you may type the
|
||||
following command line:
|
||||
|
||||
decode 0 g722_1_enc_out_24000.pak output_file 24000
|
||||
|
||||
and compare the "output_file" against the vector
|
||||
"g722_1_dec_out_24000.pcm". It should be indentical.
|
||||
|
||||
|
||||
|
||||
Background To Test Vector Design
|
||||
================================
|
||||
|
||||
The test vectors are designed to exercise as much of the G.722.1
|
||||
algorithm functionality as possible. The input test vector to the
|
||||
encoder (g722_1_test_vector.pcm) was optimized for 24kbit/s, and
|
||||
designed to access as many of the encoder/decoder table entries as
|
||||
possible (this algorithm essentially consists of table look up
|
||||
processes). The same vector may be used for 32kbit/s also - the only
|
||||
difference being in the bit rate entry, the table entries and code are
|
||||
otherwise identical at both 24 and 32kbit/s.
|
||||
|
||||
The test vector g722_1_test_vector.pcm at 24 kbit/s provides the code
|
||||
coverage results shown in the following table. The coverage is shown
|
||||
as the table (variable) size and the number (and %) of elements in
|
||||
that table which are indexed by the input vector.

||||

||||
