It takes advantage of the Fletcher-Munson threshold and the forward and backward masking effects when making 576 independent passes of each frequency band.
Its major advantage over previous attempts at the same standard is the use of a filter bank created by a discrete cosine transform, which increases the resolution by 18 times. It takes advantage of the Fletcher-Munson threshold and the forward and backward masking effects when making 576 independent passes of each frequency band. Huffman coding is used to reduce the size of the final data set, which is first minimized via the byte reservoir, joint stereo techniques, and other psychoacoustic technologies. For 10 points, the Fraunhofer institute claims a patent on what technology standard, which filters out imperceptible variations in sound files in order to create smaller but acoustically identical files that might be acquired from Kazaa, Soulseek, or a CD ripping program?
