In plain words
Alsa_rnnoise is a noise removal plugin for ALSA (Advanced Linux Sound Architecture) built on RNNoise technology. It filters out background noise from audio streams in real-time on Linux systems. The plugin uses neural network-based processing to distinguish between speech or desired sound and ambient noise, making it useful for anyone recording audio or participating in voice calls who wants to reduce unwanted background sounds during capture.
