The Finalizer features a very useful meter and work bench approach for mastering: The SPECTRO LAB!

The SPECTRO LAB is designed to give full overview of your track, both spectral- and dynamics-wise and via background calculations continually updating the views while you playback and work in real-time. Additionally, most of the processing modules you add to the project have their own representation in the SPECTRO LAB view. Thus, the SPECTRO LAB is a combined full track audio meter and processing tool laboratory that will assist you in making fast and precise mastering decisions. But remember, still ears first!

This unique mastering tool includes 3 views, selectable one at a time:

  • Spectral Dynamic Contour (SDC)
  • Real Time Spectrum (RTS)
  • Average Spectral Curve (AVG)

For each meter view, the horizontal axis shows the standard audio frequency range from 20 Hz to 20 kHz. The vertical axis shows the signal level from 0 dB (digital full-scale) down to -60 dB. 

Each meter can show either the source signal (A), the processed signal (B), or the selected reference track (REF). A, B, and REF are selected in the COMPARE section of the top line.

In the examples that follow, a new project has been created and an audio file has been added.


Real time and full track audio processing 

The SPECTRO LAB will show full track analysis (SDC and AVG) as well as real time measurement (RTS). This combination makes the SPECTRO LAB a truly unique tool for mastering, and will complement your ears and help you make decisions faster and with more accuracy. Any processing changes are automatically reflected in the full track views. 

This real time/full track approach has these benefits:

  • Adjust the processing and listen to the audio results in real time, like you are used to
  • Get continually-updated full track SDC and AVG views. You will see how all your adjustments affect the full track spectrally and dynamically
  • Get continually-updated full track descriptors: Track Loudness, True-Peak Max, and PLR (Peak-to-Loudness, describing the dynamics of the track)
  • Easily compare the source track, processed track, and reference tracks by using the COMPARE buttons (A, B, or REF)

Note: the calculations can be reset by pressing F5, but will normally be updated automatically.
