551.0. "Next step up the ladder of quality..." by ZEPPO::MAHLER (In the basement? Go up and check! - M.C. Escher) Tue Dec 02 1986 12:52


    What do YOU think the Next revolution in Audio
    firmware/software will be ?

    My vote:

	    ROM packs containing bit information that is SCANNED
	    electronically [by addressing] rather than any mechanical
	    information at all.

    Now, on to develope it and make a million or two...

    I would like to see the current digital mastering technology mastered.
    
    I would like to see super CD.   Something like 24-32 bit per word
    sampled at 100Khz.  With present optical info packing rates (optical
    is currently the space effeciency leader) that would mean CD the
    size of LVs, but then at home, space isnt that big an issue.
    
    I would also like to see the laser LP player make it since in volume
    production, this could sell in the same price structure as CD players.
    This could begin the decline of mechanical pickup cartridges (and
    their replacement, at great expense every couple years) as well
    as making LPs a little more tolerant to evil MR DUST.

    I would like to have my next audio purchase contain an auxiliary
    printer, which would make $100 bills to fund my excesses.

Creative fantasy has always been one of my strengths.

I see an audio system where the source is a cable, shared with
TV.  Every house would be like a node on a Local Area Net.  Cities
and towns would be connected via LAN bridges.  Local Area databases
would contain every recorded piece of music ever produced, in digital
format, of course.  There would be a directory, like a video 
directory (probably one combined directory) in which to select
(program) any number of selections to be fed back and played
through your system.  

Now, if I could only figure out how to make the whole thing
portable......

    What I'd like to see:
    
    A way to make polypropelene, Teflon, and polystyrene capacitors
    cheaper and smaller than electrolytic and ceramic capacitors.
    
    A way to make Teflon and fiberglass PC boards cheaper to make than
    phenolic boards.
    
    A way to make beefy torroidal transformers cheaper to use than wimpy
    E-I ones.  High capacitance/low inductance power supply caps cheaper
    than the ones often used.  Regulated power supplies cheaper than
    unregulated or poorly regulated.
    
    Metal foil (non-inductive) or metal film resistors cheaper than
    carbon composition.
                                    
    High quality DACs and ADCs cheaper than the junk in use.
    
    Then we'll have better sound.
551.4Too bad we don't hear digitally???NISYSE::GREENIDGEThu Dec 04 1986 12:0710
    An interesting improvement, if not necessarily in the cd domain,
    would (and is) digital FM broadcast.  For my own laziness, I would
    like to contain all my music in digital format on one chip which
    I could slip into my shirt pocket (or, at least one hundred of my
    cd's).  Then, I could slip the chip into any player and listen to
    whatever I wanted.  I suppose the technology will be available to
    the layman in ten to fifteen years.

    Re .4:
    
    Actually, if you think about it, we DO hear digitally.  Nerve
    pulses are simply on and off - no inbetween.  This in part is
    why I consider the arguments about the inherent "badness" of
    digital recording just plain silly.  (This is not to say that
    I consider the common IMPLEMENTATIONS of digital recording
    perfect.)

    Hear, hear!
    
    Gawd, what utter trash has been written in some audiophile mags
    about how you can't ever reproduce music using square waves.
