Have you ever wanted to remove background noise from a recording? Separate and process the vocals from a recording separately? Or remove the reverb from a vocal? Well, SpectraLayers, from Steinberg, may be the app for you.
SpectraLayers uses spectral analysis to edit and process audio tracks in different ways. Once the software has created the spectral analysis, it uses AI to remove background noise from a dialogue recording; it can separate the vocal from a backing-track to create an a cappella or instrumental; and it can clean up crackle from a vinyl transfer and remove the ambience from a recording.
Spectral analysis is a different way of viewing audio signals. The most common form of visual representation we use in DAWs and so forth views audio as a graph, with time on the x-axis and amplitude (volume) on the y-axis. A spectrogram views the audio in a slightly different way. Time is still the x-axis, but frequency is on the y-axis. Amplitude, or technically ‘density’, is shown through colour – the brighter the colour, the more dense those frequencies are in the signal.
