SURPRISING FINDINGS OF SPECTRAL AUDIO PROCESSING

We now know that the human auditory system can be modeled as a filter bank with 25 overlapping bandpass filters, or what we call 25 critical bands. We also know that if an audio signal is soft enough in level or close enough in frequency to sneak under the masking threshold of an adjacent band, that signal is masked. This ability of audio signals to mask each other under certain conditions is just one of the important human psychoacoustic characteristics making it possible to drive more energy through our new Neuron FM/HD audio processor, resulting in a fuller, more vibrant on-air sound.
