The SRC236 audio software decoding Library
is an optimized software implementation for sampling rate conversion.
It provides functions to handle the rate conversions with a ratio of 2,
3,
6, 1/2, 1/3, 1/6, 3/2 and 2/3, according to the input sampling rate.
The SRC236 module supports mono and stereo interleaved 16-bit or 32-bit
I/O data.
This Library includes one header file src236_glo.h and binary/object codes running on all STM32 devices. The naming format is SCR236_CMx_C.a/.lib, where:
- CMx: CortexMx core class (CM4 and CM7)
- C: Supported tool chains (IAR, Keil and GCC) and wchar type 32b (with IAR v8x)
The SCR236HQ_CMx_C.a/.lib libraries are specifically reserved for high quality.
The SCR236_32b_CMx_C.a/.lib libraries indicate that samples are 32 bits (rather then 16).
The SCR236_CMx_SWFPU_GCC.a libraries indicate
that it has been compiled with FPU ABI SoftFP (and not Hard) as requested by some DSP spirit libraries
For
more information about this Library, a document is under preparation
and it will be available for download from STMicroelectronics
