![]() Related to the previous tip, you may find yourself having to add tracks late in a project, while the machine is already under strain from running a heavy project. ![]() So remember to adjust your audio buffer size to suit the actual task at hand. When mixing however, record latency is almost irrelevant and instead, maximum CPU power is key. When tracking live, low latency is essential. However your needs are different at different stages of the production process. It’s generally understood that smaller buffer sizes equal lower latency but higher CPU usage, and larger buffers mean lower CPU usage but more latency. On a powerful, modern computer with solid interface drivers you shouldn’t have issues going down to 128 or even 64 samples. The key is to find a balance of CPU usage and low latency for your particular machine. This can result in dropouts if the computer is unable to keep up. However this also increases CPU load as your computer has to think about the audio even more quickly. Setting a lower buffer size (256 samples or below) will reduce latency – the lower the better in those terms. Even ¼ second gap between playing a MIDI note and hearing the result is enough to throw you. But with musical performance being so time-critical, even a few milliseconds of latency can be enough to make recording impossible. ![]() In practice this takes an extremely short amount of time – fractions of a second. The audio buffer is the small, continually active virtual space that your computer uses to store audio in the time between receiving it, passing it to software and back out again so you can hear it.
