Christophe Favergeon 60a8c8805c Corrected rescaling issue in the implementation of the MFCCs 2 years ago
Christophe Favergeon 1d9e38adca Reworked FFT initializations to make the work of the linker easier.
New FFT initialization functions to make it easier for the linker
to optimize the code size when the library is used as a static
library and can't be rebuilt.

Compilation directives for code size optimizations have been removed.

Johan Bengtsson 065e8351c3 DSP: Remove undefined behavior in post-increment/decrement read (#1443)
According to the C standard q15_t * and const q15_t * are not compatible
types which, among other things, imply that an object of type const
q15_t * can't be modified by writing to a q15_t ** or vice versa.
Programs doing this are undefined.

Because of this rule all programs using the functions read_q15x2_ia,
read_q15x2_da, read_q7x4_ia, or read_q7x4_da for reading data from an
array of constant elements will be undefined. To solve this it is not
enough to change the type of the function since this will give problems
when reading data from an array of non-const elements. To get a defined
solution I needed to switch from functions to macros to allow the
increment to be done in the original type of the pointer.

Christophe Favergeon 8092cc61f9 CMSIS-DSP: New MFCC Q15 and Q31
arm_cmplx_mag_q15 reworked to be more accurate but less efficient.

New function arm_cmplx_mag_fast_q15 introduced to retain previous
(less accurate) but faster behavior.

Improvement to Python wrapper to support the new functions.
