       | MDFourier has been an occasional discussion topic in the (video
       | game) emulation community for a few years now. Analyses showing
       | in fine scientific detail how accurately different
       | implementations are matching original hardware. In that area, it
       | has been considered somewhat of a gold standard in audio
       | comparison testing.
       | 
       | MDFourier deserves to be far better known, and widely used.
       | 
       | However, past forum discussions also highlighted that the
       | audio(phile) community does include some cynical elements whose
       | vested interests and self-built narratives would rather not be
       | exposed to hard science.

       | I have an OT question for those familiar with such software.
       | 
       | I am interested in characterizing the notes of a particular
       | musical instrument. Meaning, I want to provide it a recording of
       | a single note played once, and it should tell me the base
       | frequency of the note. Then repeat for every note. The goal is to
       | understand how different build dimensions and materials for the
       | instrument effect the frequencies of the notes.
       | 
       | Obviously, I could just do a fourier transform on each recording.
       | But I am wondering if there are specialized libraries or software
       | that make this easier, or do other interesting calculations or
       | visualizations that are currently in my unknown unknowns.
