In the classic textbook example, the Doppler effect is demonstrated by an increase in both pitch and volume (or amplitude) of a train's whistle as it approaches a station, followed by a decrease in pitch and volume as it moves away. This effect---the shift of a frequency emitted by a moving object---leads to a fundamental flaw in audio technology. A midrange driver behaves like the approaching-and-departing train when it attempts to reproduce varying frequencies. When the driver is fed simultaneous 400Hz and 2kHz tones, the forward movement of the cone at the lower rate modulates the 2kHz tone upward in pitch and amplitude; when it moves backward it modulates the higher tone downward. (The human eardrum also behaves this way, but the brain's audio-analysis circuitry knows how to deal with it.)
Rare violin dealer Geoffrey Fushi has devoted many of the past several years and a substantial portion of his liquid assets to producing The Miracle Makers, a reference book-and-recording project honoring the works of Antonio Stradivari and Giuseppe Guarneri del Gesu, late 17th- and early 18th-century makers of the world's most sought-after violins. Fushi is also the founder of the Stradivari Society, a philanthropical organization of violin fanciers who loan their invaluable instruments to gifted students. Members believe that their treasures were intended to make music, not merely to gather dust in heavily guarded vaults.
Music lovers within driving distance of San Francisco and those planning a visit for later this month should set aside Sunday, February 28, for a feast of black vinyl. That's the day the San Francisco Conservatory of Music holds its Giant LP Sale.
Musician, martial artist, and electronics whiz Ben Blish has loved audio since he was a little kid staring into the glowing tubes of his father's Scott hi-fi equipment. Thirty-four years after catching the bug, he still nurtures it daily.
Until the end of January, the Federal Communications Commission had opposed the proliferation of low-power FM radio stations. "Microradio," as it is sometimes called, has been an ongoing problem for the agency since inexpensive broadcasting gear became widely available several years ago. Primarily an urban phenomenon, microradio consists of individuals and small groups with a hodgepodge of equipment, who wedge themselves into unoccupied slots in the crowded FM band.
In January, National Public Radio launched an ambitious series chronicling the history of the 20th century in sound. Lost & Found Sound began with the first half of a two-part piece on the father of audio technology, entitled "The Rise and Fall of Thomas Alva Edison." Part two, which examines Edison's competition, will be broadcast this week.
High-end audio legend Mark Levinson has departed Cello Film and Music Systems, the company he founded 15 years ago, and has formed a new business, Red Rose Music. The new company will break all performance barriers with both affordable and cost-no-object audio equipment, Levinson stated last week, and is already registered as a new business with the state of New York.
The axeman cometh, and cometh again. Seagram Company's Universal Music Group, now the world's largest music conglomerate after last year's $10+ billion acquisition of PolyGram NV, is decimating its ranks. The company has closed the doors of several formerly independent record labels, fired hundreds of employees, and plans to unload thousands more in the next few months. Employees and artists alike will soon find themselves without labels.
MP3, the popular and controversial Internet music format, took a big step toward legitimacy last week. Z Company, which operates San Diego-based MP3.com, announced that it had attracted $11 million in venture capital from idealab! and Sequoia Capital. Z Company will change its name to MP3.com Inc. to reflect the company's core business interests, said president Michael Robertson.
Imagine that you are a Canadian with a mid-sized accounting business. You have tons of data to keep track of, and have found the recordable CD to be an excellent form of storage: convenient, reliable, and cheap---until New Year's Day, when the cost of blank discs suddenly doubled. You may not have the slightest interest in music, but one of your basic costs of doing business has just skyrocketed because someone, somewhere, has allegedly made an illegal copy of a commercial music CD.
