Some noise is more audible than others of course, and this seems never to
be mentioned. No I'll not read it, sound like my blood pressure might go up.


In the analogue days, I used a very good DBX cassette deck from Technics. On
most music it sounded wonderful as it had a lowish average level with no
high end squash, no dodgy log based Dolby to pump. However if you recorded
pure tones, yu could hear the his going up and down quite clearly, indeed
solo instruments like Piano sounded a but grainy due to this effect.
Very good compromise, certainly, but it can show how the ear can be fooled.
I guess so called high definition lossy compression like mp3 is much the
same in this respect.

Erm. At least it gave my eyebrows some exercise. :-)

Given the topic of this thread, you might also want to add in the comments
about the dynamic range of LP in this months Hi Fi Whirled.

Shows its one thing to have a spectrum analyser. Something else to know
how
to make sense of what it shows. :-) If others have read the mag,
I'll leave you to spot the 'curios' in their explanations. If you
haven't, probably better not to bother.

Out of curiosity I did a measurement using the same LPs. Came to a rather
different result. At least 30-40 dB poorer, depending on the
circumstances.
The range is actually fine, but not quite as spectacular as claimed in
the magazine.
