3D Experiments

[Tim Ressel]

To all & sundry:

I had this idea to breadboard my proposed 3D experiment using CSound. I just got
the thing working. Csound is a super-neat tool, but its a bit user-hostile.
Needs better error reporting. 

Anyway, the results with 2 delays and 2 filters is promising, but not real
impressive. The sound does move through you head, and the effect is more
pronounced than a mere pan is. However I was hoping for the sound to seem to
travel in a circle in front of you. I think more exotic filtering is needed.
Also there is some multi-path stuff that goes on around the part of your ear
called the "pinna". Three multi-paths I suspect.

Stay Tuned.

HI,
just a few personal viewpoints about measuring frequncy and synths .....
some of the better frequency counters use a phased locked loop to
multiply the input frequency so you can get better accuracy with shorter
gate time .
the Black star Apollo 100 I have got i'm happy with .
its may be easier to use something like a CONN strobotuner to tune some
of the synths / organs / electric piano's .
I know that Korg have made a tuner that has  a large diplay of led's on
it ,
is easy to see from a distance when something is in tune ......
Korg Also make a tuner that can cope with the different temperment
tunings ,
and you can set up your own unique scales .
But for general use the frequency counters in the common DVM's are great
.
would be possible to make a DIY tuner with lots of led's if anyone has
the time to design it .[ use pic's ? or Atmel ic's ]
