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 perform 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;
determining one or more properties of an environment of a wearable head device;
determining a target magnitude response based on the one or more properties of the environment, the target magnitude response comprising one or more control frequencies and further comprising a target gain corresponding to a control frequency of the one or more control frequencies;
at a second time later than the first time, retrieving the magnitude response information for the filter;
determining an audio signal based on a selected portion of the magnitude response information, wherein the selected portion is selected based on the target gain; and
presenting the audio signal to a user of the wearable head device.
