Audio Interface
Description
The audio interface equipment type is a way of acquiring and outputting on any audio device connected to the computer. This can be USB sound cards, bluetooth audio devices, internal sound cards and other audio devices. SAFE supports the preferred ASIO driver and Windows newest audio driver WASAPI. With the audio interface equipment type you can use all the channels available on the hardware, use calibrated signal chains, set sample rate, block size and many other options

Name
Name specifies the name of the block. It will automatically be given the name of the device.
Manufacturer
Manufacturer is an optional specification you can write.
Model
Model is an optional specification you can write.
Serial Number
Serial Number is an optional specification you can write.
Internal Number
Internal Number is an optional specification you can write.
Driver
Driver is the audio driver which det device should use. This is automatically selected when you use the specific device. SAFE supports both ASIO and Windows WASAPI. We recommend using ASIO if possible.
Device
Device is the name of the device supplied by the hardware. This is automatically selected when you use the specific device.
Sample Rate
Sample Rate is how many times the device samples per second given in Hertz (Hz). Default is 48000 Hz but based on what the hardware supports it can be set to other sample rates. When a device is selected SAFE will check what the hardware supports.
Resolution
Resolution is the digital resolution of the data acquired. Is default set to float32.
Block Size
Block Size is the number of samples requested by the audio interface at a time. The lower the block size the lower the latency. However a low block size can lead to clicks on outputs or overflow in the input buffer due to the PC not being able to deliver and fetch data. Our recommendation is that low latency should only be used for specific real time applications. The default block size is 4096.
Channels (IN)
Channels (IN) contains every input channel available on the hardware including analog inputs and digital inputs. To learn more about the input channels click below.
Channels (OUT)
Channels (OUT) contains every output channel available on the hardware including analog outputs and digital outputs.
