2004 honda accord EXL equipped with 6 pack cd player (honda) in dash.
Question: Playing duration seems longer as if the cd is rotating with
revolution per minute resulting with slight reduction enjoyment(ie: music)
In otherwords the effect sounds `draggy'. Is there a standard at which cd's
are oppose to spin and can it be adjusted within this honda equipment?
Thanks in advance of any/all replies.

:-) It's because of your (Canadian) metric speedometer. In America, the
speedo only shows 65, while yours shows 100 Km/hr. Try driving slightly
below the speed limit and everything will sound 'zippier'. :-)

I'm pulling your leg, of course. Maybe you're hanging out at Starbucks
too much, and your body is running too fast?

This is not possible. If the CD was spinning too slowly, it would not
extend the duration of the music, It would start skipping. CDs are not
like a record player or tape player. With those analog devices, yes,
slower speed results in slower music (and lower pitch) and a draggy
effect.

I'm sure there is a minimum speed that CDs need to spin, but most CD
players spin faster for skip protection (by reading ahead and buffering
data). BTW, CD players do not spin at a constant speed. For the inner
tracks, it spins faster. For the outer tracks, it spins slower.

In any case, you cannot change this in the Honda equipment. Most likely
is the speaker quality or EQ settings making it sound draggy.

To amplify Bucky's response, it isn't possible for the CD to spin too slowly
without the music breaking up. What we hear is actually digitized audio
being read from the CD as the player needs the data, then decoded (the CD
has a fairly sophisticated coding scheme to prevent scratches from showing
up as clicks) and sent to the speakers at a very precise rate. What this all
means is that the difference you hear comes from something other than the
rate at which the CD spins.

What Mike says is true to a point.
However, it could be that the clock for the digital-to-analog coverter could be
slow. It would be crystal controlled, and essentially not adjustable. The fix
would be a new player.

However, even a really bad crystal is many orders of magnitude better than
the human ear could discern.

Not if it cracked. Anyway, that's all I can think of that would make that much
difference, unless it's a bad clock divider - in any case, the cost-effective
solution is to replace, unless you have a lot of equipment and time.

All of that assumes that it really *is* slow - I wonder if the OP has actually
timed the length of anything on the suspect player and compared it with a
"normal" player vs. what the cd says the run time is....

Cracked crystals are dead crystals - more than 35 years experience with that
:-) I've never seen a working crystal off by enough to hear... maybe .01%.
Safe to say the actual frequency reproduction is fine, that the problem is
either output/speaker problems or perception.
