apulSoft apUnmask – is an audio plugin to amplify components of the audio that are psychoacoustically masked by other components.
To achieve this, apUnmask uses parts of the detector algorithm of the opus high-quality audio compression codec. Signal components that would get removed by compression are extracted.
These can normally not be heard as they are masked by louder components in time and frequency. apUnmask enables amplifying and sculpting the masked content and adding it to the music.
Moreover, to shape the frequencies of the extracted signal, it is fed through a linear phase graphical equalizer. It features a bezier curve smoothed frequency response without overshoot.
Features
• Insert apUnmask on the master track or an individual track to be enhanced.
• Adjust the master gain until a reasonable amount of delta signal is visible.
• Toggle the delta listen button to hear the “ghostly” sound what would be removed by the opus codec. This is what normally lives in the shadows of your music.
• Experiment with the resolution knob to find the most interesting components.
• Tweak the eq curve to extract and boost the good stuff.
• Turn off delta listen and enjoy the result.
