For instance, in the case of a typical ASIO buffer size of samples in a Most of you will have spotted that running songs at a higher sample rate means lower latency, and some musicians assume that this is a major reason to make the switch. Unfortunately, doubling sample rate also doubles CPU overheads, since twice as much data has to be processed by plug-ins and soft synths in the same time period.

You'll thus only be able to run half as many effects and notes as before, so do take this into account.

I've also mentioned in the past notably in SOS June that the setting for asio directsound full duplex interface buffers doesn't only affect latency, but also CPU overhead. However, many musicians forget this as they struggle to achieve the lowest possible latency for their system. The problem is that while the audio interface drivers take a negligible CPU overhead of their asio directsound full duplex to get started each time before the actual buffer filling and emptying takes place, and then to terminate afterwards, this small constant overhead can become increasingly significant at lower latency values.


If, for example, asio directsound full duplex buffers are running with a sample rate of But if you attempt to reduce buffer size to 64 samples asio directsound full duplex A large buffer ensures that playback occurs without audio dropout or other glitches. However, increasing the buffer size increases the audio data latency which may cause delay between the moment Audition begins sending audio data and the moment it actually reaches the physical output. In general, lowering the buffer size improves playback while increasing it will improve recording, but the goal of setting the buffer should be to find a balance between the two.
