Buffer Size
From Guide
As audio is being recorded into the computer, it is received in chunks of information. A Buffer is essentially a bin that gets filled with audio information. When the Buffer is full, the audio is written to memory or to the hard drive. Then, it is filled again. The Buffer Size corresponds to how big the Buffer is. It is often measured in number of samples. Common Buffer Sizes are 256, 512, and 1024.
The larger the Buffer, the more time it takes to fill it up. This means the audio is being written less often and CPU usage is reduced. However, monitoring latency increases as Buffer Size increases. To decrease monitoring latency, decrease Buffer Size. But a lower Buffer Size means more CPU usage. You must find a balance.
