1. A method comprising:
determining that a microphone array during a first time period is in a first discrete pose of a plurality of discrete poses, wherein the plurality of discrete poses discretizes a pose space;
retrieving a sound filter associated with the first discrete pose from a memory cache, wherein the sound filter is generated using a set of data samples identified as associated the first discrete pose from one or more data samples, and wherein each data sample of the one or more data samples comprises an audio signal captured by each microphone of the microphone array during a given time window in a second time period that is before the first time period;
generating audio content using the sound filter; and
presenting, via a transducer array, the audio content.
