VAC is the audio equivalent of a MIDI loopback device such as MultiMid or Hubi, and can be used instead of "Stereo Mix" or "What U Hear" features of audio adapters. [ 1 ] [ 2 ] If more than one application is sending audio through an output virtual cable, VAC is able to mix all of the streams together or create separate corresponding virtual ...
Loopback (also written loop-back) is the routing of electronic signals or digital data streams back to their source without intentional processing or modification. It is primarily a means of testing the communications infrastructure. Loopback can take the form of communication channels with only one communication endpoint.
The telephone company usually has the ability to remotely activate loopback, without even needing personnel at the customer site. When looped back, the customer equipment is disconnected from the line. Additional smartjack diagnostic capabilities include alarm indication signal, which reports trouble at one end of the line to the far end. This ...
Windows Vista includes a specialized QoS API called qWave (Quality Windows Audio/Video Experience), [7] which is a pre-configured quality of service module for time dependent multimedia data, such as audio or video streams. qWave uses different packet priority schemes for real-time flows (such as multimedia packets) and best-effort flows (such ...
In computer networking, TUN and TAP are kernel virtual network devices. Being network devices supported entirely in software, they differ from ordinary network devices which are backed by physical network adapters.
In some cases, loopback can be reinstated with driver updates. [10] Alternatively, software such as virtual audio cable applications can be purchased to enable the functionality. According to Microsoft, the functionality was hidden by default in Windows Vista to reduce user confusion, but is still available, as long as the underlying sound card ...
In computer networking, localhost is a hostname that refers to the current computer used to access it. The name localhost is reserved for loopback purposes. [1] It is used to access the network services that are running on the host via the loopback network interface.
To do this, the ALG FTP plugin redirects all traffic that passes through the NAT and that is destined for port 21 (FTP control port) to a private listening port in the 3000–5000 range on the Microsoft loopback adapter. The ALG FTP plugin then monitors/updates traffic on the FTP control channel so that the FTP plugin can plumb port mappings ...
