Inputs
↓ To change the number of Inputs
Note: When calculating the impulse
response, a separate impulse response
file is generated for each input.
Sum Multiplier
↓ To select the Sum Multiplier
DC Block
↓ To enable DC Block
THE ENGINEERING TOOLS
The transmission of the Output Test Signal will be started, and
the Signal button will dim, to alert the user the signal has been
loaded.
2. Use the Patch Bay (see the System Tools section of this
manual) to patch the Output Test Signal to the input of the
system under test.
There may be a need to have more than one input to the
Measurement tool. For example, when measuring the impulse
response of a room, it may be desirable to take measurements at
many different locations in the room simultaneously. Similarly,
if a microphone other than mono (stereo, binaural, B-format,
etc) is used, the Measure program will capture the impulse
response on several channels synchronously.
• Select the number of inputs required, from the Inputs drop
down combo box.
Once the number of Inputs is selected the Patch Bay will update
the number of input patch points.
The Measurement tool repeatedly outputs the measurement
signal. Synchronously, the input samples are read at the input
into a buffer. The impulse response is calculated from this
buffer. The Sum Multiplier field can be used to read a number
of sample blocks into the buffer and to average the data, which
can give a more accurate measurement of the impulse response
of a system in the presence of noise.
• Select a value from the Sum Multiplier drop down combo
box.
DC Block can be enabled to subtract any DC offset from the
final measurement of the impulse response.
• Check DC Block.
