SpectraLayers Pro
What SpectraLayers does is to let you un-mix audio files into discrete component layers using a variety of smart editing tools and process the extracted layers individually in an unlimited number of ways. You know those crime shows where the chief says can you isolate that voice from a crowded room to the tech person? Now you too can isolate that sound. To find out what you need to run SpectralLayers Pro, just check out their requirements page.
SpectraLayers is going to be a very useful tool for engineers, sound designers, audio-for-video editors, archivists, and other professionals who have the need for deep audio analysis tools. Keep in mind that SpectraLayers is different from a waveform editor – such as Sound Forge Pro that displays time vs. amplitude or volume, this is a frequency editor that shows time vs. frequencies. So the shapes that you see in the images are frequencies of sound over time.
SpectraLayers works on the ability to take those sounds, based on their frequencies, and isolate them to separate and discrete layers. That is done through the process of extraction. SpectraLayers contains a number of extraction tools that predict what the selection you are trying to make and really works to make the process easy.
The first type of extraction tries to isolate sound based on frequency. This tool tries to isolate the frequency of the sound so that it can be moved to a new layer. Once the sound is isolated then the sound can be inverted which when apply against the original sound produces an effect called phase cancellation.
When you have two identical sounds that are just the opposite in wave form they will cancel each other out and thus eliminate the sound. So when you need to isolate and hear that voice the chief wants, you just eliminate all the other sounds that muffle it using these techniques.
