Abstract: An apparatus for processing a multichannel audio signal has a plurality of channel signals. The apparatus performs a time scale modulation of the multichannel audio signal and has a phase adaptor and a separator. The phase adaptor provides a processed signal by modifying a phase of a signal based on a combination of the channel signals. The separator provides separated signals based on the processed signal. A corresponding method is provided.

Abstract: Disclosed is a system and method which provides hardware and software that in combination create an automated intermediary between parties to a transaction. The invention provides a fully automated solution that permits the creation of new markets where service level agreements (SLAs) or laws, rules and/or regulations (LRRs) require knowledge of the location of a party at some point or points in time in order to permit or facilitate the transaction. The system and method of the invention provides not only an automated auditing mechanism to demonstrate compliance with SLAs and LRRs, but by acting as an intermediary between customers and suppliers, also allows location information to remain confidential while still using it to satisfy SLAs and LRRs. The system permits and facilitates transactions between and among parties that have a defined commercial or other transactional relationship, at least one of which may be remote and using a wireless communications device.
