Buffer Size
The setting Buffer Size determines the latency between incoming and outgoing ASIO and WDM
data, as well as affecting system stability (see chapter 7.1).
USB Diagnosis shows specific USB transmission errors (CRC5, usually 0) and general errors.
If the unit detects a record or playback error the number shown will no longer be 0. An audio
reset is performed automatically. The counter is reset on start of playback/record. More informa-
tion can be found in chapter 20.1.
Sample Rate
Display of the currently active sample rate. Its setting / change takes place exclusively via the
AVB Controller. Neither WDM nor ASIO programs can change the sample rate.
WDM Devices
Allows to freely set which I/Os are available as WDM devices, if these are stereo or multi-
channel devices (up to 8 channels), and if one or multiple of the currently active WDM devices
should have the Speaker property. Digiface AVB provides a maximum of 64 channels under
WDM, corresponding to 32 stereo or 8 multichannel devices. More details are found in chapter
7.2.
Options
Word Clock In Term.
Checking this option terminates the word clock input internally with 75 Ohms.
Word Clock – Single Speed
The word clock output signal usually equals the current sample rate. Selecting Single Speed
causes the output signal to always stay within the range of 32 kHz to 48 kHz. So at 96 kHz and
192 kHz sample rate, the output word clock is 48 kHz.
Iso(chronous) Streaming (USB 3 only)
The Digiface AVB uses a special transmission mode with error correction in record mode. In
case the default mode does not work Isochronous Streaming can be tried. This is the standard’s
native mode for audio transmission and should work with any USB 3 controller. See also chap-
ter 20.1.
Input Status
Word
Indicates presence of a valid signal at the word clock input (Lock, No Lock) and whether the
signal is synchronous (Sync). The third column shows the sample frequency detected by the
hardware (coarse recognition, 32 kHz, 44.1 kHz, 48 kHz etc.).
