7. A wearable system comprising:
a wearable head device comprising one or more sensors and one or more speakers; and
one or more processors configured to execute a method comprising:
determining magnitude response information for a filter, the magnitude response information comprising a plurality of gain values, at least one of the plurality of gain values including a first gain corresponding to a first frequency;
at a first time, storing the magnitude response information for the filter;
at a second time later than the first time, retrieving the magnitude response information for the filter;
for a control frequency of a plurality of control frequencies including the first frequency, determining a gain based on the retrieved magnitude response information of the filter and further based on an output of the one or more sensors;
determining an audio signal based on the determined gain; and
presenting the audio signal to a user via the one or more speakers.
