Virtual Audio Cable is a software solution for realizing audio connections between applications. The way it works is by using the input port to record the audio signal and send it to a program, such as an analyzer or sound processor, via the output port.
The program's interface can easily be described as simple and resembles much older software tools from the Windows XP era. It doesn't have any alternative theme skin or other options to customize the appearance. Also, for a novice user, navigating through the menu may be difficult, so you should read the documentation before you start using the program.
With Virtual Audio Cable, users can connect a wide range of audio applications, like speech synthesis, audio recorders, virtual machines, VoIPs, or software-defined radios.
In addition to that, it offers multiple configuration options, such as setting the number of instances, modifying the sample and bit rates, enabling buffer watermark, or volume control.
Overall, Virtual Audio Cable is a decent software program for connecting several audio applications, but it should be used only after a proper documentation process. One more thing that you should take into consideration is that it's not free, and once the trial has expired you may find the price to be too high.
