miniDSP Ltd, Hong Kong / www.minidsp.com / Features and specifications subject to change without prior notice 19
7.1.3 NOISE SUPRESSION
This setting controls the Noise Suppression algorithm for up to 20dB of Noise Reduction.
NS: [0, 1]: 0: off, 1: on */
NS_attlimit_dB: [-20..0]: noise attenuation in dB
7.1.4 DE_REVERB
The De-reverb technology removes room reverberation effects .It gives the feeling the talker is closer to the
microphone and can remove up to 20dB of non –stationary reverb.
rvb_on; /* [0, 1]: 0: off, 1: on */
rvb_attlimit_dB; /* [-20..0]: reverb attenuation in dB */
7.1.5 ACOUSTIC ECHO CANCELLATION (AEC)
The onboard AEC block can be used to remove echo during.
aec_on; /* [0, 1]: 0: off, 1: on */
aec_delay_ms; /* [-1, 0..30]: -1: auto, 0..30 AEC delay [ms] */
