| 1 This Hg repository contains a mostly-raw import of GSM-HR speech codec | |
| 2 implementation from the original GSM 06.06 publication. The only modification | |
| 3 that has been made is a minimally-invasive surgical change to gsm_hr.c (the | |
| 4 main module) that allows the default noisy output to be suppressed at run time, | |
| 5 rather than at compile time, and suppresses all of this noisy output rather | |
| 6 than just one part of it. Also a Makefile has been added, for straightforward | |
| 7 compilation on "semi-modern" systems such as Slackware Linux. | |
| 8 | |
| 9 This work has been produced for two purposes: | |
| 10 | |
| 11 1) To make it possible to actually run this original GSM-HR code, before the | |
| 12 laborious effort of librifying it and incorporating it into gsm-codec-lib, | |
| 13 and for verification. testing and comparison after that planned work. | |
| 14 | |
| 15 2) To have the code readily available in a public Hg repository, allowing | |
| 16 direct links to individual files or even to line numbers. Such easy linking | |
| 17 ability is needed to facilitate analysis and discussion of various aspects | |
| 18 of this reference code. |
