1. A method of equalizing an audio system, the method comprising:
receiving, using at least one microphone of a portable computer device, test audio played by one or more loudspeakers of the audio system in a room, the test audio generated based on audio signals, wherein the receiving of the test audio using the at least one microphone of the portable computer device includes moving the portable computer device about the room while the test audio is being played by the one or more loudspeakers of the audio system in the room;
determining a time delay between the generation of the test audio and the receiving of the test audio by correlating the generation of the test audio and the receipt of the test audio;
calculating at the portable computer device, based on the time delay, a frequency response;
calculating at the portable computer device, based on the frequency response, audio parameters to be used for equalizing the audio system;
transmitting the audio parameters to the audio system directly or indirectly from the portable computer device to the audio system;
saving, in memory of the audio system, the audio parameters for equalizing the audio system; and
applying, to the audio system, the audio parameters for equalizing the audio system.
