CONFIG_COMP_ASRC¶

ASRC component

Type: bool

Help¶

Select for Asynchronous sample rate conversion (ASRC)
component. The ASRC has the capabilities of (synchronous)
SRC but can in addition track a slave DAI that is not in
sync with firmware timer. The ASRC can be setup for
synchronous operation without DAI tracking via topology
though it has a bit higher computational load than SRC. The
RAM footprint of ASRC is smaller than SRC because it does
not have pre-computed filter coefficients for every
conversion fraction that SRC does.

Direct dependencies¶

SOF

(Includes any dependencies from ifs and menus.)
