THE BAS MESSAGE
January 2026 |
Miscellaneous News
1.
Letter to BBC
Music Magazine
In your 2025 issue
p99 it mentions RMS
power.
That
term is meaningless.
The product
of rms volts and rms
amps is power or
continuous power,
not rms power. What
continuous power
means is determined
by regulatory bodies
such has FTC in the
USA, and specifies
duration, amplitude
and frequency.

cause—DBH]

JUST RELEASED !
A fantastic historical video!
Ken Berger and Kenton Forsythe are the founders of EAW (Eastern Acoustics Works) and they discuss, with terrific overlaid graphics, the history of, well, pretty much every audio thing Boston from the early 70's.
18 minutes and right here: https://youtu.be/fPfQEK0b0mI

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
Mahler 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: Mahler 3 Zander as FLAC.zip 1GB

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:
Shop Talk John Allen talks to Scott Kent on SPEAKERS.mp3 (81Mb 1:27)
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]

| BAS 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.
Joseph DeMarinis has an article here: Extracting Numerical Data from an Excel Trend Line
