ANR configuration in Smart Remote 3

[HL_JC]

To configure ANR in the Smart Remote 3 for nRF52 PCA63519 sample firmware, CONFIG_AUDIO_ANR_DELAY_LENGTH must be assigned a value in sr3_config.nrf52832_pca63519.h.

CONFIG_AUDIO_ANR_DELAY_LENGTH is described as the "Distance between noise and voice microphones". Is this value expressed in millimeters or some other unit?

The unit is samples. (It may help to see at this screenshot and answer in general on this library: https://devzone.nordicsemi.com/f/nordic-q-a/39389/sr3-v1-2-anr-question-active-noise-reduction)
