Define a measurement sequence

A measurement sequence is defined by a series of steps. Each step is in turn defined by a variety of elements, called Tracks. Below is an example of a simple sequence.


How to add steps#

Use the + buttons between the steps to add or duplicate steps.

Click a step to select and then press the delete key to delete a step.

When selected you can configure the steps global properties in the Properties Panel.

These are the types of steps available at the moment:

  • Step
  • Repeater
  • Pause

Pre delay timing#

Pre-delay is the time that that lapses before each step begins.

This is useful when you would like to make a step and require a specific amount of time to pass before the measurement begins. In the Properties Panel you have the option to choose how long the pre delay is both numerically and the unit whether seconds, milliseconds or samples.

Measurement time#

Measurement time is the overall time taken to complete the step.

When developing tests, time keeping is an understated essential and provides you with many conveniences. In the Properties Panel you have the option to choose how long the measurement time will be, whether seconds, milliseconds or samples.

How to run the sequence#

There are 3 ways to run the sequence or individual steps in the sequence.


  1. The big Run button runs the sequence from the begging to end, regardless of what step is currently selected.
  2. The top right run button will run only the currently selected step, and then stop.
  3. The bottom right button will run the sequence from the currently selected step, until the end.

Each button is only enabled if the steps related to the button is ready to play.

How to configure steps#

In the Tool Panel you can find the available tracks for the measurement steps.


Drag a track to a step to add it to the step. If you double click a track in this panel it will be inserted in the currently selected step.

Click on a track to select it and edit its attributes in the Properties Panel.

The Equipment category in the Tool Panel is all the equipment currently on the Configuration board. Each type of equipment has a default track type that is created if an equipment is dragged to a step.

  • Microphone default to Recording tracks
  • Loudspeakers default to Output tracks


How to record data#

To record data, you will need to drag a Recording track to a step. The next step is for you to drag the sensor to required area. You can also drag the microphone that you want to record with, to a step, and the recording track is created automatically.

When the data has been recorded the graph will update and display at most noble unit available on the sensor.


You need to have configured a sensor to record data. Read more here.


How to playback stimuli#

To initiate a playback of any of the stimuli, first you will need to have added an Output track to a step. After adding the track you will need to drag your transducer to the prompted location. Still its possible to drag the transducer directly to a step, and create the output track automatically.

Output tracks come default with a certain stimuli, fx Noise. You can add several stimuli to each track by dragging another output track to an already created track.

Double click the plot of an output track to show the individual stimuli. Here you can also delete stimuli from an Output track.


You need to have configured a transducer to playback. Read more here.


Select the output track to configure the stimuli attributes in the Properties Panel.

How to add context to your measurements#

Adding context to a step can be very important. Remember that without context, data can be difficult to remember in the future, or for others to replicate.

Under the section of measurement tools you will find tool types to help you give the proper context for your steps and for the data obtained. These tools are Text and Picture. There are more on the way.


To add text context, drag the Text track from the Tools Panel into the a step. The text track will then provide you with a text field where you can note for example equipment settings, equipment positions etc. This text will also be part of the Report, if generated.

To add picture context, drag the Picture track from the Tools Panel to the a step. Click the track and insert the path to your picture in the Properties Panel.
