Steinberg SpectraLayers Pro 13

With both new and improved module options, SpectraLayers Pro 13 has plenty to tempt those specialising in post‑production tasks such as dialogue enhancement, audio restoration or sound design.

Steinberg’s spectral editor opens up yet more powerful processing options.

Spectral editing has come a long way over the last five years. Great strides have been made in terms of capabilities for this kind of software (for example stem separation/unmixing) and in how users can access and utilise what are very sophisticated audio processing tools. Much of this has been underpinned by rapid advances in machine learning/AI technology.

All of which perhaps helps to explain why Steinberg maintain a regular annual update cycle for SpectraLayers Pro. So, fairly hot on the heels of v12 (reviewed in the October 2025 issue of SOS), we now have SpectraLayers Pro 13. This release certainly has its share of new and improved processing modules, but there are also some significant workflow and UI refinements. So, if SLP is an integral part of your audio workflow, is there enough that’s new or improved to make SLP13 a worthy upgrade?

In Repair

There is plenty to explore as SLP13 delivers a number of new modules. While v12 perhaps focused more on music‑orientated unmixing options, in v13, the emphasis seems to be placed on audio post‑production tasks such as voice/dialogue processing and audio repair. For the latter, the new Reconstruct module lets the user resynthesize spectral data within a file and, while the Heal option it replaces could only reconstruct the background noise, Reconstruct also attempts to rebuild both transient and tonal components based upon materials located around the region selected for repair. Providing you are working on relatively small areas (for example, an area where you have deleted a spot noise), the process can do a rather impressive job of filling the gap, supplying both signal and noise components.

Equally impressive is the new Ambience Heal module. This is most obviously useful where you have applied an unmixing process (for example, separating dialogue from its background) which has left some ‘holes’ within the background layer. Rather cleverly, Ambience Heal uses information from the ‘foreground’ layer (for example, the layer with the extracted speech) and uses this to guide where the ambience in the background layer might need repair. VO/dialogue editors will find this useful once any extracted vocals are themselves cleaned, enhanced or replaced, as they can be dropped back into a more uniform ‘healed’ ambience backing track for a smoother result.
