===Latency===
The larger the buffer is, the more time it takes to fill it by digital audio data. Large buffers increase the time required for processing audio in computer, this delay is usually called '''latency'''. Every system has certain limitations - too small buffers involving negligible latencies cannot be smoothly processed by computer, so the reasonable size starts at about 32 samples. The processor load does not affect latency directly (it means, once you set certain buffer size, the latency is constant), but with very high processor loads the processing starts dropping out. Increasing buffer size or quitting other application helps to keep playback smooth.
===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 an 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.
