Abstract:
1. A method for calibrating user headphones to improve the accuracy of recorded audio content reproduced thereon, comprising: determining characterizing of reference microphones of a type used to record said audio content to indicate a first audio coloration caused by the microphones when located proximate to a listener's ears; determining characteristics of said microphones to indicate a second audio coloration caused thereby when located proximate to the ears of a dummy head; determining characteristics of reference headphones of a type corresponding to said user headphones to indicate a third audio coloration caused by the reference headphones when used to reproduce audio content; computing an equalization signal ΔE based on the first, second and third audio colorations; and applying the equalization signal to calibrate said user headphones during playback of audio content that was recorded using microphones of a type corresponding to said reference microphones.
