1. A method for equalizing audio at an electronic device located in a defined space, comprising:
outputting first audio content from at least one speaker of the electronic device;
capturing, via a plurality of microphones, audio data representing a set of reflections of the first audio content within the defined space;
obtaining, by a processor of the electronic device, a feature vector indicating a set of characteristics of the audio data that was captured via the pluraity of microphones;
obtaining, by the processor, a frequency correction based on the feature vector; and
applying, by the processor, the frequency correction to subsequent audio content.
