Steinberg released SpectraLayers 13 on July 1, 2026. This is the version that stops treating audio repair as cutting and starts treating it as rebuilding. The update adds a batch of second-generation AI modules aimed squarely at post-production. The standouts are Unmix Sound Effects, Reconstruct, and Ambience Heal, and together they push the software from a repair tool toward a genuine reconstruction tool.
Key facts: SpectraLayers 13 is out now. Pro costs €359 (upgrade from €289), Elements is €89.99, and a free Go tier ships bundled with select products. It runs standalone and as an ARA 2 extension in Cubase, Nuendo, and other hosts, on macOS 12–26 and Windows 10/11. More than 25 new features ship in the box, and the headline nine are new modules.
What is SpectraLayers?
SpectraLayers is Steinberg's spectral audio editor. It displays sound as a spectrogram, a visual map of frequency over time, so you can select, isolate, and edit individual sounds the way you would retouch a photo. It sits in the same category as iZotope RX, the go-to toolkit for repairing damaged recordings, removing noise, and pulling a finished mix apart into stems. Film, TV, podcast, and game-audio teams rely on it for the unglamorous rescue work that saves a take.
The layers concept is what sets it apart. Everything you extract lands on its own editable layer — a voice on one, footsteps on another, room tone underneath — and you mix, mute, or export those layers independently. Version 13 extends that model with modules that don't just remove problems. They reconstruct what should have been there in the first place.
What's new in SpectraLayers 13?
The update centers on new and improved modules, most of them Pro-tier, backed by a long list of workflow upgrades. Here is what actually matters for editors.
Unmix Sound Effects is the headline module. It separates short, discrete sounds — a door slam, a cough, a bird call — from continuous environmental beds like wind, traffic, crowd, or nature. The isolated effect moves to a dedicated layer while the background texture stays intact. Dialogue and post editors have wanted this for years. You can now lift the sound you need without gutting the ambience around it.
Reconstruct resynthesizes selected spectral data. It rebuilds tones by tracking the material before and after a selection, transients by tracking above and below, and noise as its own component, each with a configurable amount. Instead of leaving a hole where a sound used to be, you fill it with a synthesized continuation of the surrounding audio.
Ambience Heal is the natural partner to unmixing. Once you pull a voice or effect out of a layer, it fills the empty space with the surrounding background texture that is already present, such as room tone or environment. It reads your foreground layers to work out what to remove and what to keep.
Voice tools get a serious upgrade. Unmix Two Voices separates two speakers without registering voice profiles first. Voice DeCrosstalk pulls background or foreground voices away from a primary speaker even when they overlap. Voice DeClick removes lip smacks and tongue clicks using threshold, width, and reduction controls. For dialogue editors, that trio covers most of the daily grind.
Attenuate tames high-amplitude content inside a selection relative to the surrounding spectral power, so patched-in material blends naturally. Level Check calculates True Peak and a range of LU loudness measurements across selections or any combination of layers, and the playhead snaps to the exact points where instantaneous readings were taken. Fade applies fades within a layer or crossfades between two layers, with automatic fade-type detection.
Steinberg's own overview walks through the new modules in action:
Beyond the modules, the workflow additions earn their place. You get Paste Into Selection and Paste Insert for repeating or replacing events, corner-based selection resizing that adjusts time and frequency at once, interface layout presets, module search by keyword, and batch processing across multiple open projects. Keyboard shortcuts now cover more than 100 functions. The Pro Tools AudioSuite bridge also gained round-trip editing of multiple clips, plus support for Dolby Atmos up to 9.1.6 and Ambisonics.

SpectraLayers 13 vs iZotope RX
The obvious rival is iZotope RX, the other industry-standard spectral-repair suite. The two overlap heavily on de-noise, de-click, and unmixing, but their tiers and strengths pull in different directions. RX recently moved under Boris FX, which we covered in our report on iZotope joining Boris FX, and that reshuffle is worth weighing if you are picking an ecosystem now.
| SpectraLayers 13 | iZotope RX | |
|---|---|---|
| Full-tier price | €359 (Pro) | $1,399 (Advanced) |
| Entry price | €89.99 (Elements) | $99 (Elements) |
| Editions | Pro, Elements, Go | Elements, Standard, Advanced |
| DAW integration | ARA 2 (Cubase/Nuendo + others) | ARA + AudioSuite plugins |
| New SFX unmixing | Unmix Sound Effects (dedicated) | Dialogue/ambience via separate modules |
| Spectral rebuild | Reconstruct + Ambience Heal | Spectral Recovery, De-rustle |
| Best home | Steinberg/Cubase ecosystems | Film/TV post, Pro Tools rooms |
Here is the honest read. iZotope RX still owns some dialogue-repair territory outright, and the module depth in its Advanced editor is hard to beat. But SpectraLayers Pro costs roughly a quarter of RX Advanced, and its new Unmix Sound Effects and Reconstruct modules cover ground RX does not handle as cleanly. If you live in Cubase or Nuendo, the ARA 2 timeline integration in SpectraLayers makes it the smoother fit. If you already run a Pro Tools post room built around RX, the math tilts the other way.
Who SpectraLayers 13 is for
This release targets post-production. It is built for dialogue editors, sound designers, and re-recording mixers who need to isolate, rebuild, and clean audio with precision. If that describes your work, the Pro tier's new modules pay for themselves quickly. Music producers who occasionally pull a vocal or de-noise a stem will find Elements more than enough. And if you only need the odd de-click or hum removal, you don't need SpectraLayers at all, since a cheaper single-purpose tool will cover it. Producers weighing full instrument and effect suites might also look at our Omnisphere 3 review for a different corner of the software landscape.
How much does SpectraLayers 13 cost?
SpectraLayers Pro 13 is €359 at full price, with upgrades from €289 and updates from €89.99. SpectraLayers Elements 13 is €89.99, with updates from €34.99. The Go tier is free and bundled with select Steinberg products. Both paid editions include the ARA 2 extension for Cubase, Nuendo, and other hosts, and a trial is available.

FAQ
What is new in SpectraLayers 13?
The big additions are Unmix Sound Effects, which separates short sounds from continuous ambience, Reconstruct, which resynthesizes missing tones, transients, and noise, and Ambience Heal, which fills unmixed gaps with existing room tone. It also adds Attenuate, Voice DeClick, Unmix Two Voices, Voice DeCrosstalk, Level Check, and Fade. On top of that come more than 25 workflow improvements, including batch processing across open projects.
Is SpectraLayers 13 worth upgrading from 12?
For anyone doing post-production, yes. Unmix Sound Effects and Reconstruct are genuinely new capabilities, not refinements, and Pro upgrades start at €289 with updates from €89.99. If you only use SpectraLayers for occasional music-production cleanup, the upgrade is less urgent.
SpectraLayers 13 vs iZotope RX — which should I buy?
SpectraLayers Pro is far cheaper than RX Advanced, at €359 against $1,399, and it integrates more tightly with Cubase and Nuendo through ARA 2. RX still leads on some dialogue-repair modules and suits Pro Tools post rooms. Pick SpectraLayers if you work in the Steinberg ecosystem, and consider RX if you are already invested in it.
What are the system requirements for SpectraLayers 13?
It runs on macOS 12 through 26 on Intel and Apple silicon Macs, and on Windows 10 and 11 21H2 or newer, including Windows 11 on Arm 24H2. The installer needs roughly 4.2 to 4.3 GB of disk space.
