1. A system for determining the impulse response of an environment, the system comprising:
an audio emitting unit operable to emit a predetermined sound in the environment;
an audio detection unit operable to record the sound output by the audio emitting unit; and
an impulse response generation unit operable to identify an impulse response of the environment in dependence upon a frequency response of the audio emitting unit and/or the audio detection unit, and a difference between the predetermined sound and the recorded sound, wherein:
a user within the environment is directed to generate one or more sounds,
the audio detection unit is operable to record the one or more sounds generated by the user, and
the impulse response generation unit is operable to generate the impulse response of the environment in dependence upon the one or more sounds recorded in addition to those emitted by the audio emitting unit.
