Meeting Notice for September 2019

Date: Sunday, Sep 22, 2019 @ 6:00 PM
Place: Boston University, Life Science & Engineering Bldg, 24 Cummington Mall, 1st Floor, Conference Room 103, Boston, MA 02215
Guest: Alvin Foster and Nick Noiseux

Topic: BAS & Local Musical Menus, & Meeting Summary Writers Wanted

This is a hands-on meeting of members to discuss including more music in our pursuit of hi-fi excellence. Most of our past meetings are geared to analyzing audio equipment, and understanding the electronics behind the products.

Because Boston has many great music venues, why not include meetings at selected halls preceded with a lecture on the hall's acoustics and the history of the upcoming music? Of course, Jordan, and Worcester halls come to mind but small, lesser known halls would be included.

Is there a way to get group discounts at selected halls and to prearrange a room for the acoustical lecture.? Will parking be a problem?

The second agenda item will include catching up on writeups of previous meetings for the newsletter. The BAS now pays meeting summary writers $150. Over the years, we have a backlog of unreported meetings. It’s easy, the entire meeting can be supplied on a CD. How can we get more writer participation?

There will be refreshments at 5:30

Directions: Note that parking is no longer allowed in the block in front of our meeting place (temp parking for unloading/loading is OK). There is a gap in the BU buildings on Commonwealth Ave. so you can walk through directly to the meeting location.

At Boston University, Cummington St. (Mall) is an east-west street just south of Commonwealth Ave. It is one-way going west. From Storrow Drive going east, take the first BU exit. At the stop sign turn right on Commonwealth Ave (a left is not permitted). Bear left and at the 3rd light take a u-turn, go half a mile and turn right on Blandford St.(Mall) (at a traffic light) and turn right on Cummington St. (Mall) The entrance is on your left, number 24.

From Commonwealth Ave going west, after Kenmore Square, after the tracks come up out of the tunnel, there is a traffic light at Blandford. You should turn left on Blandford, but no left is permitted. Instead turn right and make a U-turn. Continue on Blandford and turn right on Cummington St. The entrance is on your left, number 24.

MBTA Green line - exit at Kenmore Square or the next stop, Blandford St. & Commonwealth Ave. Walk a short distance and make a left turn onto Blandford Mall and then a right onto Cummington Mall.

Parking is free on Sundays and available on Commonwealth Ave. and Beacon St. (take a hard right at Kendall Square and park on the bridge and take the stairs down) and Bay State Rd (parallel to Commonwealth Ave next to the river)

Use your GPS (!)

— Webmaster's note: Google maps and Apple maps show them as Blandford Mall and Cummington Mall. Bing maps shows them as Blandford Street and Cummington Street. YMMV.


The BAS Message
September 2019

1.  In 2018 sales of classical music increased faster than any other type of music. Streaming rose 42 per cent. CDs are still 60 per cent of the market and sales rose by 6.9%.

2.  A couple months ago I wrote about great conductors, giving Willem Mengelberg as an example. I found a link which has all his recorded legacy available for listening: www.willemmengelberg.nl/?q=discografie

Here it is the message, repeated.

I am a fan of the art of conducting and great conductors. Something is lost with today’s note-perfect bland performances. An example from the past is Willem Mengelberg who conducted the Concertgebouw Orchestra of Amsterdam for 50 years. His use of rubato (agogics) is unique and sometimes jaw-dropping.

Here is a historic example from Tahra Records TAH 391, last mvt Beethoven 3rd, live from 1942: dbsystemsaudio.com/meng.mp3.

His recorded legacy for listening is here:
www.willemmengelberg.nl/?q=discografie

There is a new biography by Frits Zwart (The last one was in 1930!).

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)

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 a new article here: Extracting Numerical Data from an Excel Trend Line
