Description of the CD tracks
The CD included in the Spl-Lab equipment distribution kit alongside with software contains
specialised audio tracks with test signals for adjusting a system. Consider that these tracks are
recorded not in the file form, but as tracks in Audio-CD format. For playing back the tracks from
the CD use specialised software or CD player. It is possible that some CD player models will not
read the audio content of the CD. In such case or if it is more convenient for you to use the audio
files, download the archive with test signals from
