Dynamic selection of appropriate far-field signal separation algorithms

A system, comprising:

• a controller configured to perform operations comprising:
• receiving a first audio data;
• processing the first audio data by a first signal separation algorithm;
• in response to an output of the first signal separation algorithm satisfying at least one parameter, outputting the processed first audio data;
• and
• in response to the output of the first signal separation algorithm not satisfying the at least one parameter:
• selecting a second signal separation algorithm, which is different than the first signal separation algorithm;
• receiving a second audio data subsequent in time to receiving the first audio data;
• processing the second audio data by the second signal separation algorithm;
• during the processing of the second audio data, transitioning from the first signal separation algorithm to the second signal separation algorithm in response to selecting the second signal separation algorithm, wherein the transitioning from the first signal separation algorithm to the second signal separation algorithm comprises:
• matching a first audio stream of the first audio data with a second audio stream of the second audio data based on a direction of the first audio stream and a direction of the second audio stream;
• fading out the first audio stream;
• and
• fading in the second audio stream;
• and
• outputting the processed second audio data.
