The
January 2023 ZOOM ONLY Meeting
The
Second Half of the AES New York Show
|
Date: Sunday,
January 29, 2023, 7:00 PM – 9:00 PM
Place: online Zoom session only
TOPIC: Finishing up the AES New York
review (also NAB show)
This month will finish
reporting the AES show Alvin and I went to
in October 2022. We will feature an interview
with Tomasz Zernicki – the founder of
Zylia which produces a unique Soundfield type
microphone. You will see Alvin and myself
interacting with the Zylia VR demo environment.
It was a first for me. The NAB show was held
in the other half of the hall. It featured
mainly networking environments, data storage
and backup facilities, studio management software,
and studio hardware (mixers, monitors, etc.).
We also will present
short interviews and demonstrations of other
interesting manufacturers.
We hope that you will
have interesting things to bring up in our
Open Forum Session.
The meeting will be
Zoomed only as there is only A/V material
to present.
I hope to see you then.

THE
BAS MESSAGE
January 2023 |
|
1. More silly stuff
KEVALIN AUDIO, North
American distributor for WAVERSA SYSTEMS,
invites you to explore a new, passive digital
filter technology unique to the industry,
the EXT
Digital Noise Isolators. While details
are closely held due to patent conditions,
this military-based technology has proven
effective in digital audio reproduction, producing
notable improvement in both audio and video
performance. Collin Shin, CEO of Waversa Systems,
says, ‘This module “forms an electric
field and a magnetic field to remove RFI noise
from the LAN cable and noise generated by
the digital signal line itself.”’
Waversa’s proprietary technology is applied
differently at each level of the series, the
EXT-1, EXT Reference, and EXT Reference Plus.
The line includes models for:
• LAN Ethernet
• USB
• Coax (RCA, BNC,
and AES/EBU)
• HDMI
All three models are
totally passive, do not require a power supply,
and are non-directional. All are supplied
with a short-run cable to be placed between
the filter and the destination component,
usually the final piece in the digital transmission
chain.

A Boston issue - As MIX magazine
reports:
Sound
Museum owners cry foul as their tenants likely secure
new spaces without them
While the headline sounds
like someone has sour grapes, the complete story
of how the closure of this crucial Boston rehearsal
studio is being handled is far more nuanced and
complicated -- particularly since it brings up issues
of gentrification, government support of the arts,
non-profits' ethics and more. Full Story HERE
(WBUR-FM Boston (1/11/23)

MAHLER
3
In the recent
(April 2022) performance of Mahler’s Third
Symphony at Boston's Symphony Hall by Ben Zander
and his Boston Philharmonic, the recording was done
with the three main spaced omnis with two more farther
back. No accent mikes or chorus microphones were
used nor, it turns out, were they needed. Remarkably,
this produced a recording that is as close to the
Symphony Hall experience as may be possible.
The info is
here: www.bostonphil.org/concerts/2021-2022/bpo4-mahler3
Here is the
recording in its entirety as a single .WAV file;
44k / 16 bit; 1hr 47 min

Sym 3 CD.wav 1.1GB
(For those of you with editing software note that
the .wav file HAS markers to denote the movements.)
Here is the
exact same Symphony 3 with the movements separated
as FLAC files, 48k / 24 bit as a ZIPped file:

Shop
Talk
Shop Talk was
a WBUR program about Hi Fidelity, music, speakers,
tape recorders, etc. Enjoyed by many during the
1970s, the program's format was ‘talk’
and interviewing major audio luminaries. It was
a forerunner of the popular program Car Talk!
Peter Mitchell and Dr. Richard
Goldwater were the original hosts. They were later
joined by Brad Meyer. Here, John Allen interviews
Scott Kent:

Talk John Allen talks to Scott Kent on SPEAKERS.mp3

Shop
Talk John Allen talks to Scott Kent on TAPE RECORDERS.mp3
(79Mb 1:26)
There is also an episode track
on the BAS
CD and here is that Description:
Track 12. "Shop Talk",
WHRB-FM, November 5, 1984.
Peter Mitchell (on the left), Richard Goldwater,
MD (center) and E. Brad Meyer (right) introduce
the show with a 1932 stereo recording and prepare
to talk with guests Mark Davis and David Moran,
both then of dbx corporation.
Shop Talk, which through most
of its ten-year life on WBUR featured just Mitchell
and Goldwater, was the precursor of Tom and Ray
Magliozzi's "Car Talk". As we finished
our 9:00-10:30 stint every Saturday morning, Tom
and Ray would take our places and begin joking
with each other. Eventually the station manager
figured out that they were funnier than we were,
and that more people drove cars than owned hi-fi
equipment, and fired us. Until then, the show
publicized the Boston Audio Society, vastly increasing
attendance at our monthly meetings. The show came
back for a time during the '80's on the Harvard
station WHRB, where we appeared once a month as
guests of HRB stalwart David Elliott. [EBM]

MICROPHONE CLINIC REPORT ! |
| In September 2009
the B A S held a microphone clinic, testing 37 different
microphone models. The ambitious nature of the clinic
effort, the extent of data collection, the number
of individuals involved in microphone testing and
in writing various sections of the report, and the
complexity in determining how to construct the clinic
report and make it available to members resulted it
not being published until now. The dataset is extensive.
Representative samples were
included in the abbreviated report in "The
B A S Speaker"
(Fall 2015; v37n3)
Go to the MICROPHONE
CLINIC PAGE for more...
...and don't
forget, here is the master
list of microphones in the world

When collecting
and plotting "noisy" data
it is often useful to have Microsoft
Excel plot a Trend Line through it.
If that data is to be used for
further work, it may be necessary to
have an X-Y table of the Trend Line.
That is not easy to get and this paper
will show how to do it.

has an article here: Extracting
Numerical Data from an Excel Trend Line
