Abstract

An apparatus for processing audio data comprising an interaural time delay correction factor unit for receiving a plurality of channels of audio data and generating an interaural time delay correction factor. An interaural time delay correction factor insertion unit for modifying the plurality of channels of audio data as a function of the interaural time delay correction factor.

Claims (5)

1. An apparatus for processing audio data comprising:

means for receiving a plurality of channels and determining a time delay between peak magnitudes for a plurality of frequency bands;

and an interaural time delay correction factor insertion unit for modifying the plurality of channels of audio data as a function of an interaural time delay correction factor.

2. The apparatus of claim 1 wherein the interaural time delay correction factor insertion unit comprises means for modifying the plurality of channels of audio data as the function of the interaural time delay correction factor.

3. The apparatus of claim 1 wherein the interaural time delay correction factor insertion unit comprises means for delaying a channel of audio data by an amount related to a delay of the interaural time delay correction factor unit.
