In Studio One, the Audio Setup / Audio Device / Device Block Size setting in the Preferences dialogue sets the basic buffer size. Small buffer sizes create less delay, so recording is best done using the smallest workable buffer size, but smaller buffer sizes also push your processor harder, and this proves to be the limiting factor in how small a buffer you can use. It also complicates the use of virtual instruments, which get delayed as well. Recording is impacted by buffer size because buffering necessarily introduces latency (delay) in monitoring the source, and monitoring delay is difficult to stomach when recording a performance. But this buffer turns out to sit at the center centre of competing priorities, a fact that has engendered no small amount of confusion around buffer size settings. In DAWs, this stability is ensured by the use of a buffer, a short-term ‘staging area’ your processor can use like counter space in a kitchen to make processes more efficient. When audio data is moved around, it absolutely must be received and played on time, or bad things happen.
With Studio One’s advanced features, latency need not be a problem. A nice, short, 32-sample buffer is in use here, yielding perfectly workable latencies of less than a millisecond. Screen 1: The Audio Device preferences pane.
