==Principle of operation==

The audio signal from the input is transformed to the digital (a stream of numbers) in audio hardware and passed to a piece of computer memory, called [[buffer | buffers]]. Then it is modified according to a specific algorithm, which creates the desired effect. After this operation, the signal is transformed from digital to analog and sent to the output.

===Drivers===

====Microsoft Windows====

Microsoft does not provide technology for low latency audio processing. That's why most of the professional applications use ASIO drivers by Steinberg. The ASIO driver is bundled with the audio hardware. If the HW manufacturer doesn't provide ASIO drivers, there is ana universal ASIO driver named ASIO4ALL, which can be used for any audio interface. ASIO drivers can be emulated, in this case the driver name is ASIO Multimedia. However, the latency when using these drivers is very high.
