SummaryRecommendation ITU-T G.191 provides source code for speech and audio processing modules for narrowband, wideband and super-wideband telephony applications. The set includes codecs, filters, noise generators. This edition introduces changes to Annex A, which describes the ITU-T Software Tools (STL) containing a high-quality, portable C code library for speech processing applications. This release of the STL, also known as STL2024, incorporates: • BS1770demo improvements: – a new RMS option disabling the gating function for background noise measurement, – the handling of the edge case where all gating blacks are below −70 LKFS, – improved reporting with scaling factor being reported in the linear and log domains. • WMC Tools updates: – New command line parameter to allow control on the number of frames per second (default still 50) – Export information on all memory allocations occurring during runtime – Example script for graphical analysis and profiling of dynamic memory allocation – Bugs fixes and code improvements. Recommendation ITU-T G.191 includes an electronic attachment containing STL2024 and manual. |
