The Last Sultan: The Life and Times of Ahmet Ertegun by Robert Greenfield 431 pages. New York: Simon & Schuster, 2011. Hardcover, $30.

Robert Greenfield's engaging biography shows that Ahmet Ertegun was destined to dominate. The son of a Turkish ambassador, Ertegun (1923–2006) left his native country at age two, and lived for a decade in Switzerland, France, and England, where he had a nanny who had previously cared for the Princesses Elizabeth and Margaret Rose. His first American home was an architectural gem of a mansion on Washington's Embassy Row. House guests included Cary Grant and his second wife, the Woolworth heiress Barbara Hutton.

The New Analog: Listening and Reconnecting in a Digital World, by Damon Krukowski. The New Press, 2017. Hardcover, 240 pp., $24.95. Also available as an e-book.

Defining noise is tricky business.

In high-end audio, noise is often defined as the enemy—of music, beauty, truth. Engineers and enthusiasts alike spend significant amounts of time, energy, and money attempting to minimize or control noise so that it has the least possible impact on the source signal: music. In this way—if we are intelligent, careful, and fortunate—we can extract from our stereos cleaner, clearer, more naturally beautiful sound for listening experiences that are enriching, emotionally compelling, and, above all, fun. On the other hand, when noise is allowed to excessively modulate the signal, music can sound relatively abrasive, more mechanical, and, ultimately, less engaging.

In December 1941, just after Japan's attack on Pearl Harbor and the U.S.'s declaration of war, the state of Indiana unwittingly endorsed a very different conflict by approving the incorporation of a talent agency headed by Denver Ferguson, an Indianapolis-based African-American entrepreneur. The Chitlin' Circuit and the Road to Rock 'n' Roll documents the second of these campaigns, launched by the musical forces Ferguson dispatched to venues throughout the American South where blacks could entertain black audiences. In successive waves, talented musicians hit those stages running. Their performances were often incendiary, and a large chunk of this book chronicles the artistic warfare they waged between the advent of rhythm and blues and the emergence of what became known as rock'n'roll.

In "Music and Fractals" in the November 1990 issue, I discuss how digital audio's quantization of amplitude information in what was originally a continuous waveform represents a fundamental difference between analog and digital representations of music. In a letter published in the English magazine Hi-Fi Review in January 1990, John Lambshead conjectured that naturally originating sounds were pseudo-fractal in character; that is, their waveforms have a wealth of fine detail, and that detail itself has an even finer-structured wealth of fine detail, and so on, until the crinkliness of the waveform is finally enveloped in the analog noise that accompanies every sound we hear.

The issue is this business of "single-speaker" listening and demonstration, which has become fashionable in the UK.

The premise: bringing a second pair of loudspeakers into your auditioning room upsets the sound of the pair you're listening so badly that the first speaker's ability to correctly reproduce the timbre of musical instruments is destroyed. This observation is almost surely correct.

Until the Recording Industry Association of America hit the headlines in recent years with its antipiracy campaign, the initials RIAA meant one thing to seasoned audiophiles: the vinyl-disc equalization characteristic introduced in the 1950s to standardize what had previously been an anarchy of different EQs. Three decades later, as CD gained ascendance, a large proportion of audiophiles still knew what RIAA equalization was, and a good number of them had some idea or better of what the RIAA EQ curve looked like, and why it was applied.
