Steinberg SpectraLayers 12 – Spectral Editing & AI Unmixing, $39.99

Waveform editors show you how loud a sound is over time. SpectraLayers 12 shows you the sound itself. Steinberg’s spectral editor renders audio as a visible spectrum — frequency stacked against time — and then lets you work on it the way you would work on a document: select the vocal out of a finished mix, erase a cough from an interview, lift a single instrument off a master, repair damage that waveform editing declares impossible. At $39.99 on this board, that capability costs less than a single hour of restoration work billed out, and then it stays on your machine for every job after.

See It, Select It, Fix It

The visual approach changes what is editable. With frequency-based and time-based selection tools, you can isolate a sound by its spectral fingerprint rather than its position in a waveform, copy and paste audio between different frequencies, and use the clone stamp tool to replicate and replace audio segments the way photo editors heal images. Advanced noise reduction and restoration tools handle the classic rescue work — damaged recordings, unwanted artifacts, vintage material with decades of grime — while real-time spectral processing and preview mean you hear every edit as you make it. Unlimited layers let complex projects stack separations, repairs and designs without flattening your options away.

AI Unmixing: Stems From Finished Mixes

The headline technology is the unmixing. An advanced stem separation engine, built on neural network processing, can isolate vocals, drums, bass and other instruments from mixed recordings with remarkable accuracy. Producers use it to extract stems from finished mixes for remixing and sampling — acapellas and instrumentals that were never released become working material. Restoration engineers use the same machinery in reverse, separating what belongs from what does not. Film sound editors lean on it for production dialogue cleanup, pulling voices forward out of locations that fought them on the day. This is capability that simply has no equivalent in a traditional waveform editor.

Plugged Into Your DAW, Built for Volume

SpectraLayers 12 integrates with professional DAWs through ARA2, so the spectral editor lives inside your existing workflow instead of beside it — open the editor on a clip, repair it, and keep arranging. Batch processing capabilities handle the unglamorous reality of professional work: folders of production audio, archives of interviews, libraries of samples needing the same fix applied a hundred times, processed while you do something else. It runs on Mac and Windows, equally at home in music production, post-production and sound design suites.

Restoration Work That Used to Be Impossible

The restoration applications deserve their own emphasis, because this is where spectral editing stops being a convenience and becomes the only option. Vintage recordings arrive carrying clicks, crackle, hum and damage layered across decades; in a waveform editor those flaws are welded to the music, but in the spectrum they occupy visible territory that can be selected, healed with the clone stamp, or rebuilt from neighbouring audio. The same precision serves everyday production: a chair squeak under the perfect vocal take, a guitar string buzz in the one good performance, a door slam inside dialogue recorded on location. Each lives somewhere in the spectrum, and SpectraLayers 12 hands you the map and the tools in the same window, with the visual interface making complex repairs accessible rather than arcane.

The Deal

There is no strikethrough price on this one because the proposition is already stark: $39.99 for the spectral editing platform engineers reach for when every other tool says the job cannot be done. One rescued recording — the interview that cannot be re-shot, the live take that cannot be re-performed, the master that cannot be re-mixed — repays that many times over in a single afternoon. Board it now and the next impossible audio problem becomes a selection you can see, grab, and fix.
