  1. Why Class D should be a moral imperative

    Well, normally it's subjective, but it's objectively subjective. However, with class D this subjectivity enters a pure void of negativity and can only be experienced as deprivation...so it sucks.

  4. Audiophilia Syndrome

    Are you thinking of some of the neuroscience and music literature?
  5. Audiophilia Syndrome

    "This is the first time a study has demonstrated that when we imagine music in our heads, the auditory cortex and other parts of the brain process auditory information, such as high and low frequencies, in the same way as they do when stimulated by real sound." https://actu.epfl.ch/news/that-music-playing-in-your-head-a-real-conundrum-f/ Abstract Despite many behavioral and neuroimaging investigations, it remains unclear how the human cortex represents spectrotemporal sound features during auditory imagery, and how this representation compares to auditory perception. To assess this, we recorded electrocorticographic signals from an epileptic patient with proficient music ability in 2 conditions. First, the participant played 2 piano pieces on an electronic piano with the sound volume of the digital keyboard on. Second, the participant replayed the same piano pieces, but without auditory feedback, and the participant was asked to imagine hearing the music in his mind. In both conditions, the sound output of the keyboard was recorded, thus allowing precise time-locking between the neural activity and the spectrotemporal content of the music imagery. This novel task design provided a unique opportunity to apply receptive field modeling techniques to quantitatively study neural encoding during auditory mental imagery. In both conditions, we built encoding models to predict high gamma neural activity (70–150 Hz) from the spectrogram representation of the recorded sound. We found robust spectrotemporal receptive fields during auditory imagery with substantial, but not complete overlap in frequency tuning and cortical location compared to receptive fields measured during auditory perception. https://academic.oup.com/cercor/article-abstract/doi/10.1093/cercor/bhx277/4566611?redirectedFrom=fulltext Next up: "How to get audiophile quality from imaginary sound"
  6. Why Class D Sucks

    it would be interesting to see a study of the effects of cognitive rigidity on the ability to enjoy class D amplification. "Cognitive rigidity gets amplified by time pressure, negative emotions, exhaustion, and other stressors."

    WHAT IS IT LIKE TO BE A BAT? https://warwick.ac.uk/fac/cross_fac/iatl/activities/modules/ugmodules/humananimalstudies/lectures/32/nagel_bat.pdf Apart from its own interest, a phenomenology that is in this sense objective may permit questions about the physical basis of experience to assume a more intelligible form. Aspects of subjective experience that admitted this kind of objective description might be better candidates for objective explanations of a more familiar sort. But whether or not this guess is correct, it seems unlikely that any physical theory of mind can be contemplated until more thought has been given to the general problem of subjective and objective. Otherwise we cannot even pose the mindbody problem without sidestepping it. I have not defined the term "physical." Obviously it does not apply just to what can be described by the concepts of contemporary physics, since we expect further developments. Some may think there is nothing to prevent mental phenomena from eventually being recognized as physical in their own right. But whatever else may be said of the physical, it has to be objective. So if our idea of the physical ever expands to include mental phenomena, it will have to assign them an objective character-whether or not this is done by analyzing them in terms of other phenomena already regarded as physical. It seems to me more likely, however, that mental-physical relations will eventually be expressed in a theory whose fundamental terms cannot be placed clearly in either category.

    Another consequence of the facile equation objective-real/subjectivity-indefinite-or-imprecise is the seemingly pervasive idea that there has to be a physical correlate to something in the mind in order for a subjective experience to be ‘real’. Subjectivity is completely experiential. Simply understanding chemical processes in the brain that lead to it does not make it any more or less real, and nor can it provide an explanation of that subjective experience. Author of Bad Science Dr Ben Goldacre has written eloquently about what he cites as this ‘neuro-realism’: “All mental states have physical correlates, if you believe that the physical activity of the brain is what underlies our sensations, beliefs and experiences: so while different mental states will be associated with different physical states, that doesn’t tell you which caused which…. But far stranger is the idea that a subjective experience must be shown to have a measurable physical correlate in the brain before we can agree that the subjective experience is real, even for matters that are plainly experiential. If someone is complaining of persistent low sex drive, then they have persistent low sex drive, and even if you could find no physical correlate in the brain whatsoever, that wouldn’t matter, they do still have low sex drive. It’s a slightly strange world when a scan of blood flow in the brain is taken as vindication of a subjective mental state, and a way to validate our experience of the world.”
