Make a .wav-file and write it to the CD

If you are able to record the signal with your playback device, we recommend that you follow the procedure in the next section instead of the procedure that follows below.

The sampling frequency has been set to 44100 Hz. In the figure below, we see that the length of the sweep is 20 seconds and there is 3.8 seconds of silence after each sweep.

The number of measurement cycles is 16, which means that there will be 16 sweeps in the wav-file. The total file length will be 380 seconds. Use only one sweep for a single measurement, but we use the number 16 if you need to do several measurements (e.g. measure in several positions). To increase the number of sweeps that are played you can either increase this number, or set the CD-player in repeat modus.

Export the measurement signal to a .wav-file using Measurement->Export Stimulus....

This file will be given a name that contains the measurement parameters as shown below.

Now use your CD-recording software to write this file to a CD.

The result of the measurement may not be quite as good as when using the sound card to playback the measurement signal since the CD-player and the sound card may have slightly different sampling frequencies. But if you use a single sweep as the measurement signal, this should not be a problem.
