AUTOMATIC AUDIO SYSTEM EQUALIZING

摘要

An automated process for equalizing an audio system and an apparatus for implementing the process. An audio system includes a microphone unit, for receiving the sound waves radiated from a plurality of speakers, acoustic measuring circuitry, for calculating frequency response measurements; a memory, for storing characteristic data of the loudspeaker units and further for storing the frequency response measurements; and equalization calculation circuitry, for calculating an equalization pattern responsive to the digital data and responsive to the characteristic data of the plurality of loudspeaker units. Also described is an automated equalizing system including a acoustic measuring circuitry including a microphone for measuring frequency response at a plurality of locations; a memory, for storing the frequency responses at the plurality of locations; and equalization calculation circuitry, for calculating, from the frequency responses, an optimized equalization pattern.

主权项

1. A portable computer device comprising:
a microphone for receiving and transducing sound waves, acoustic measuring circuitry coupled to microphone for measuring acoustic responses of the sound waves received and transduced by the microphone; a processor coupled to acoustic measuring circuitry; a memory coupled to the processor; and a software program stored on the memory, which, when executed by the processor, causes the processor to: cause instructions to be communicated to a user, the instructions directing the user to move the microphone to different locations in a listening space; cause the microphone to receive sound waves radiated by a loudspeaker as the microphone is moved to different locations in the listening space; cause the acoustic measuring circuitry to measure a plurality of acoustic responses as the microphone is moved to different locations in the listening space; and while the acoustic responses are being measured, determine if the ambient noise exceeds a predetermined threshold; and if the ambient noise exceeds the predetermined threshold, generate a message.
