Abstract

A method for processing audio signals (900), which contains: the audio signal (602A, 602B) included in space information into a set of audio signal components; and processing according to the first processing scheme (603) processing(902) The first subset (606A) of the group of audio signal components and the second processing scheme (609) that is different from the first processing scheme (603) of the first processing scheme (603)Sub -set (606), wherein the first subset (606A) includes the audio signal component corresponding to at least one positive signal source (m) and the second subset (606) includes at least one environmental signal source (SL, SR) audio signal components; wherein the second processing scheme (609) is offset based on string disturbances.

Description

technical field [0001] The invention relates to a method for processing audio signals and a mobile device applying such a method. The invention further relates to an audio system for creating an enhanced spatial effect in a mobile device, in particular an audio system applying crosstalk cancellation. Background technique [0002] There are many devices with two converters on the market, such as laptop computers, tablet computers, mobile phones and smartphones, as well as iPod or smartphone docking stations and sound bars for TVs. In contrast to a conventional stereo system with two discrete speakers, the two transducers of such devices are located in a single cabinet or enclosure and are usually placed very close to each other (due to the size of the device, they are usually only a few centimeters apart, Between 2cm and 30cm for mobile devices such as smartphones or tablets). For typical listening distances such as figure 1 The loudspeaker span angle θ illustrated in a is...
