Sweetwater Live Sound and Recording Final Exam with verified solution What is Latency? (Term) - Latency refers to the period of delay between when an audio signal enters and when it emerges from a system. The longer the signal has to go and the more resistance it encounters, the higher the latency. So a signal has to go through the converter, to the sound card, to the motherboard of the computer where it meets the operating system. If any of these parts creates resistance for the signal, it shows in the latency when the sound goes to the output. The idea of latency can be thought of like a train going from station A to station E. The train can get to station E fastest by going straight there. However, there are 3 essential stops that it has to go to first and each stop causes the train to be later and later. When the train finally gets to station E it is at the output and the time that it took to get from A to E is the latency. One of the problems with this is that monitoring becomes difficult because the signal is not getting to your ears at almost the same time as you see it going into the source. This is the same with playback. A couple of ways to fix this would be to cut down how far the signal has to travel or get a word clock to help regulate signals.

(term) - A DAW is a Digital Audio Workstation. The software programs are usually able to record, manipulate and playback audio. With a DAW you can have all the mixing, processing, and mastering on one computer. There are many different DAWs such as, Pro Tools, Logic, Ableton, Cubase, etc. Some DAWs run off your computer while others need a card that helps process all of the digital info. Plug-ins are also available with most DAWs. Plug-ins are small, "helper" programs that work inside your DAW to extend it's capability. So a DAW is like your car and the aftermarket accessories like tinted windows, new exhaust, etc. are the plug-ins. You can easily use the factory parts for the car and it will run just fine. However, the aftermarket accessories help make it unique to you and give you more of what you want. The PreSonus AudioBoxUSB connects to the computer using which of the following? A. USB B.
