15.1.5.2 Developer
15.1.5.2.1 Windows APIs
Wave/Mixer
– Meters are read using mixerGetControlDetails() on a control of type signed and with type “Peak”
the name “Peak Meter”. A minimum value is 0 and maximum is 32767. The interface returns the peak readings
only, not the RSM level. It confirms to expected Windows functionality.
HPI
– Meters are read using the
HPI_Meterxxx () API.
ASX
– Meters are read using the
ASX_Meter_xxx () API.
DirectSound
– TBD.
15.1.5.2.2 Linux APIs
HPI
– Meters are read using the
HPI_Meterxxx () API.
ASX
– Meters are read using the
ASX_Meter_xxx () API.
ALSA
– TBD.
15.1.6 AES/EBU I/O
The Hono CobraNet 2.2D and 4.4D have AES/EBU I/O.

Hono CobraNet 2.2D
– 1 AES/EBU output and 1 AES/EBU input (2 channel I/O)

Hono CobraNet 4.4D
– 2 AES/EBU outputs and 2 AES/EBU inputs (4 channel I/O)
15.1.6.1 AES/EBU Inputs
Each AES/EBU input has a sample rate converter (SRC) on it and so may have a sample rate that is
asynchronous to the rest of the system. Valid sample rates are 32, 44.1, 48, 64, 88.2 and 96kHz.
15.1.6.2 AES/EBU Outputs
The AES/EBU outputs are clocked at 48kHz, the same rate as the CobraNet interface and cannot be changed.
15.1.7 Input and Output Volume Adjustment
All outputs from the Hono Mini CobraNet interface have volume adjustments in their path that support a range of
–
100 to + 20 dB. The nodes that support this are CobraNet_Ch 1-8, Analog_Out 1-4 and AES/EBU_Out 1-2.
Clicking on CobraNet_Ch 1 in the
topology pane of ASIControl will show
a list of volumes in the node view
pane. Below is an image of the first
volume shown in the node pane. The
meter is found after the list of volumes
(the Hono Mini CobraNet interface
incorporates AudioScience’s ‘anything
to anywhere) mixing).

Figure 8. ASIControl node displays with volumes
The volumes are self-explanatory. Just drag the sliders. All lineouts also have an audio path (with volume) from
the corresponding line in. This can be use useful in verifying the correct operation of the audio modules without
having to send the audio across a CobraNet network.
