- CONFIG_INTEL_DMIC_FIR_DECIMATE_BY_6¶
FIR decimate by 6
Type: bool
Help¶
This includes FIR coefficients to decimate by 6 into the build. It
is commonly used for 16 kHz capture from secondary FIFO while
primary FIFO is configured for 48 kHz rate.
Direct dependencies¶
INTEL_DMIC && SOF
(Includes any dependencies from ifs and menus.)
Default¶
n
