What is a duplex sound card
Q: What is the sound card of simplex and duplex ah? What’s the difference? Integrated sound card is a simplex or duplex ah?
I recently bought a PCI sound card, installed the original driver disk driver, but found that this PCI sound card does not support full-duplex and does not support multiple applications at the same time audible, which is why not?
A: You certainly never made a phone call, when you speak and can hear each other’s voice, which is the basic concept of full-duplex, but full-duplex sound card on the concept is not only in this way, strictly speaking, the sound card The full-duplex means recording at the same time can play a sound work, and vice versa, this is the real full-duplex operation, but full-duplex, or the lack of the most commonly appear in the network or the use of Net Meeting phone applications, such as, if genuine support full-duplex sound card, then you use Net Meeting or Internet telephony should be with the general call is the same, if half-duplex, so long as one side will not hear the speech of each other’s voices, on the if in the use of general walky talky. Sound card is designed to complete two kinds of basic work, one for recording, one for playback, the only two kinds of work can be called at the same time only true full-duplex.
Duplex sound card Definition: refers to the so-called full-duplex sound card in the side to play a sound, while also recording the voice of one side, the PCI does not support full-duplex sound card should now be gone. Your PCI sound card does not support audible at the same time, mostly because you did not use the new version of the driver, do not blindly believe in the original driver disk drivers, drivers go home ( Audio Classification 1, full-duplex mode (full duplex) 2, semi-double-type way (half duplex) No related posts.
When the data to send and receive streaming, respectively, from two different transmission line transmission, communications both sides carried out at the same time to send and receive operation, this is a full-duplex transmission system. In full-duplex mode, communication systems are set up each end of transmitter and receiver, therefore, can be controlled at the same time data transmission in both directions. The need for full-duplex mode switch direction, and there is no switching time delay arising from this for those who can not have the time delay of interactive applications (such as remote monitoring and control system) very favorable. This approach requires communication both transmitter and receiver at the same time, the need for two data lines to transmit data signals. (May also need to control the line and state lines, as well as the ground).
If using the same both for a transmission line to receive it for transmission, although the data can be transmitted in both directions, but the two sides could not at the same time communication to send and receive data, such a delivery system that is half-duplex. The use of half-duplex mode, the communication systems of each side of transmitter and receiver, through the admission / fat switch to receive online communications, to carry out the direction of the switch, therefore, will have the time delay. / R switch is actually controlled by software of electronic switches.
