Abstract
A computer apparatus is provided, which has a multipath acoustic output system and a multipath acoustic input system, which includes parts for enabling an adaptation of the filter of an acoustic echo canceller incorporated in the computer apparatus that is always precise regardless of the chronological delays of the components of the computer apparatus, wherein the chronological delays are variable for acoustic signals.
Claims3
A computer apparatus having a multipath acoustic output system and a multipath acoustic input system, comprising:
- first parts for digitally processing one of acoustic data to be outputted and received acoustic data;
- second parts for editing and forwarding the acoustic data provided by the first parts to an output and forwarding to the first parts the received acoustic data;
- and
- third parts for, respectively, converting the edited acoustic signals into analog acoustic signals, and for acoustically outputting the converted analog acoustic signals via at least one single line of the output multipaths and by at least one single first acoustic converter, and converting, for the second parts, into digital acoustic data, via at least one single line of the input multipaths, the analog acoustic signals accepted by at least one single second acoustic converter;
- wherein at least one of the output multipaths is connected to at least one of the input multipaths, with the first parts reproducing an acoustic echo elimination circuit which, on the input side, is connected to the input multipath which is connected to an output multipath and, on the output side, is connected to an input multipath that is connected to the second acoustic converter, and wherein at least one connection between an output multipath and an input multipath is a short-circuit connection.
