8.7 Low Latency under MME (Buffer Size Adjustment)
Using Windows 95 or 98 the MME buffer size was nothing to worry about. Latencies below 46
ms were not possible. Meanwhile both computers and operating system have become much
more powerful, and since Windows ME/2000/XP latencies far lower can be used. SAWStudio
and Sonar allowed to use such low settings from the start. Sequoia was updated in version
5.91, WaveLab in version 3.04.
In the Settings dialog the MME buffersize (in fact the DMA buffer size) is set with the same
buttons as the ASIO buffer size. Please note that this setting only defines the buffer size of the
hardware. The true and effective latency is configured within the MME application!
Attention: the DMA buffers must not be larger than the application's buffers. This case can
happen unnoticed when using ASIO and MME at the same time (multiclient) and setting
MODE to 2048 (46 ms), while the buffers in the MME application are still set for a lower la-
tency. Playback will be stuttering and audio will be distorted.
Example: when you set the DIGI96 to 2048 you can't use 1024 in any program. But setting the
card's MME buffer to 256 allows to use 512 and all higher values within the MME software.
