What's new?
- 3/21/08
Summarizing statement added to the Home page.
- 3/12/08
A little homage to special friends: Russ Riley,
Lyman Miller, Brian
Elliott
- 3/10/08
Added an Analog to digital conversion
page to Digital Photo Processes.
- 2/29/08
Added a Sharpness page to my camera
investigation.
- 2/25/08
Added photos from my Audio Artistry era to the Links
page.
- 2/22/08
I added an addendum to Suggestions and
hearing.
- 2/20/08
I am posting the Digital Photo Processes pages. This will
highlight my limited bandwidth issues and probably force me into a more
costly hosting plan. But then there is always the Website
CD.
- 2/15/08
A 1999 paper by B. Moore that deals with "Controversies and mysteries in spatial
hearing" came to my attention again. I had
forgotten about it. It would have helped me to understand the reason for the
surprising similarity between an omni and a dipole in a reverberant room
right away.
- 2/13/08
It is likely that the website will be down on the 21st day of each month due
to heavy traffic, but it will always resume on the 22nd when my 50 GB/mo
bandwidth allowance period starts up again.
- 1/1/08
I added the "cocktail party effect" to the paragraph about "Sound
stream segregation" on the "Recording for stereo" page.
Some readers were apparently confused about what Don is trying to
accomplish.
- 12/22/07
In case you wondered why the website was shut down yesterday for several
hours, I had reached my monthly bandwidth allowance of 50 Gigabyte. Today
starts a new monthly pay period with my ISP.
If you own the Website CD, then you have access
to 99% of the information here at all times and you probably will not notice
any future interruption.

The UK Chapter of the Audio Engineering Society keeps a full record of
monthly talks on its
website. The great variety of audio related subjects is educational and
interesting.
- 12/20/07-2
I receive about 300 email messages per day. 98% of that is junk and I just
pull out those that have a relevant subject line. So be clear with the
subject if you want to get through my Spam filter. Before writing please
read my CAUTION.

The Orion
User Group is a good place to ask questions, get help and make contact.
It also applies to PLUTO.
- 12/19/07-2
If you are thinking of designing a box loudspeaker, then read Loudspeaker
System Design. It covers many fundamental issues.

A reminder to those who have bought documentation from LINKWITZ LAB. On the
cover is the URL for a support page. Check it for the latest updates.

My recent talk in London gives a summary of what has been learned here about
loudspeaker design for accurate sound reproduction in relatively small
rooms. ORION+ and PLUTO+ embody the key features that a loudspeaker must
have. I hope that these prototypes will stimulate eventually some new
loudspeaker developments for the high-end audio market so that a wider
audience can hear what a simple 2-channel sound system is capable of. I am
not holding my breath, though. The industry, its marketers and commentators
are firmly locked into vented boxes and no fresh air comes in. Besides, the
profit in this business is in cables, spikes, room tuning, etc. and now
compact speakers for the iPod generation, but their hearing might be already
damaged.

The first and last links in the left hand column should let you find quickly
what is new on the website by pointing to this page. This new page also gives me a convenient place to add
timely comments.
