I switched to Acon Digital's Acoustica Premium edition years ago, and happily uninstalled SpectraLayers shortly thereafter. Acoustica is a superb audio editor, and the Premium edition includes a great spectral editor. Also included are the excellent Restoration Suite and Mastering Suite plugins, making the Premium edition an excellent value for the money. The developer is very responsive, almost as responsive as the app itself. It opens lightning fast and has a great GUI. It also now supports ARA2 if you use a DAW like Studio One that can take advantage of that capability. Audacity may be free, and it may be all you need, but money spent on Acoustica is money well-spent IMO. Your mileage may vary.
