• wherein the audio hub comprises first communication interfaces, a second communication interface, a second processor, and a memory;
• wherein the second processor is a digital signal processor and wherein the first processor is a host processor or an application processor;
• wherein the first communication interfaces are configured to exchange audio signals with a group of audio components of different types;
• wherein an aggregate number of first communication interface bits exceeds a number of second communication interface bits;
• wherein the audio signals comprise input audio signals received from the group and output audio signals transmitted to the group;
• wherein the second processor is configured to generate an input multiplex of input audio signals;
• and
• wherein the second communication interface is configured to transmit the input multiplex to the first processor and to receive an output multiplex from the first processor.
