— Output Channel Status —
The Output Channel Status section lets you set the
channel status bits for the PCI-822 coax outputs to
either Consumer (SPDIF) or Pro (AES/EBU). The default is SPDIF.
If you have an external SPDIF-to-AES/EBU level converter, you can
use it with the Pro (AES/EBU) setting to generate true AES/EBU
output from the PCI-822.
— Buffer Size —
The Buffer Size indicates how often data is processed
between the PCI-822 hardware and its driver. Smaller
buffer sizes yield faster response times (lower latency), which most
noticeably affect audio functions such as monitoring inputs in the
Patchbay, using output from GigaSampler or the ASIO driver in Cubase
VST. Larger buffer sizes provide more protection against audio
glitches. The default setting is 256 samples. We recommend that you
set the buffer size as large as possible while attaining suitable latency
for your audio.
You must close all audio applications before you change the
Note:
buffer size or ASIO resolution. The new setting takes effect when you
restart the application(s).
— ASIO Resolution —
You can set the resolution for recording and playback
to either '16 bit' or '24 bit' when using the ASIO driver in applications
such as Cubase VST. You may also need to set the resolution in the
application itself. For example, to record and play 24-bit audio in
Cubase VST, you have to enable its '24-bit' button.
You can use 24-bit resolution when recording or playing 16-bit digital
audio, but it is slightly less efficient than using 16-bit resolution.
On the Macintosh, the PCI-822 has two different ASIO drivers — one
for 16-bit audio, and one for 24-bit audio. Either can be selected
within an ASIO-compatible application.
