CONFIG_COMP_TDFB¶

TDFB component

Type: bool

Help¶

Select for time domain fixed beamformer (TDFB) component. The
beamformer component enhances microphone capture by spatial
suppression of noise and improvement of signal-to-noise ratio of
capture from beam direction. The component is essentially a generic
single rate FIR filter bank that performs microphone array
directivity enhancement when programmed with suitable configuration
for channels selection, channel filter coefficients, and output
streams mixing.

Direct dependencies¶

SOF

(Includes any dependencies from ifs and menus.)

Default¶
