What is Buffer Size?

Buffer Size is a setting in digital audio systems that determines how much audio data is processed at one time. It is known for affecting both audio latency and system performance.

The buffer typically stores a small chunk of audio before it is processed by the CPU, with sizes measured in samples (such as 64, 128, 256, or higher).

Buffer Size emphasizes the balance between latency and stability: smaller buffer sizes reduce latency but require more processing power, while larger buffer sizes increase latency but provide more stable performance.

It is commonly adjusted in digital audio workstations and audio interfaces depending on whether the priority is real-time recording or mixing with heavy processing.

Today, Buffer Size is an important parameter in audio production, valued for its role in optimizing performance, preventing glitches, and ensuring a smooth recording and playback experience.
