Sample rate converter (SRC) Setup Tools ======================================= This is a tool to set up SRC conversions sample rates list, define quality related parameters, and test the C implementation for a number of objective audio quality parameters. The tools need GNU Octave version 4.0.0 or later with octave-signal package. src_std_int32.m --------------- This script creates the default coefficient set and contains nothing else but call for src_generate. src_tiny_int16.m ---------------- This script creates the tiny coefficient set. The script contains an example how to customize the input/output rates matrix and in a simple way the scale conversions quality. More controlled quality adjust can be done by editing file src_param.m directly. Note that int16 presentation for SRC coefficients will degrade even the default quality. src_generate.m -------------- Creates the header files to include to C into directory "include". A report of create modes is written to directory "reports". The coefficients need to be copied to directory sof.git/src/include/sof/audio/coefficients/src. The default quality of SRC is defined in module src_param.m. The quality impacts the complexity and coefficents tables size of SRC.
