Music sounds

This passage details the rise and fall of the Seattle grunge-music sound in American pop culture of the 1990s. 

On the neutral, but scientifically exciting, edge there is again some musical sound distortions... 

Some applications for modifying the envelope of a musical sound include producing a slower attack onset for a piano. This produces the effect of a bowed piano . This can be a very musically useful sound. Other examples include ramping the decay of a sound to zero faster than the sound normally does. This can be used to increase the effective damping of a drum sound, for example. 

In addition to FM signals with nested modulators, Justice also considered a class of signals modeled by a harmonic sum of sine waves with a slowly varying amplitude, typical of many speech and music sounds...

Transient signals. The previous results are related to the case of steady portions of musical sounds, however it is well-known that musical recordings also feature many transient parts (note onsets, percussions) that play an important part in the subjective assessment of the signal characteristics [Flail, 1980, Deutsch, 1982],... 

In Chowning s original work [Chowning, 1973], he explored three different classes of musical signals brass tones, woodwind tones, and percussive-like sounds. An important characteristic of these musical sounds, in addition to their spectral composition, is the amplitude envelope of the sound and its relation to its instantaneous bandwidth. 

Alternatively, a more realistic music attack or speech plosive may be obtained by splicing into die synthesized deterministic component using the method described in section 3.6. Splicing of the actual attack has been shown to significantly improve the sound quality for a number of musical sounds including the piano and marimba [Serra, 1989]. Hybrid sounds can also be created by matching the sine-wave phases of the attack of one sound with the phases of the deterministic component of a second sound at a splice point.

It was in these bordellos, where music provided the background and not the primary focus of attention, that marihuana became an integral part of the jazz era. Unlike booze, which dulled and incapacitated, marihuana enabled musicians whose job required them to play long into the night to forget their exhaustion. Moreover, the drag seemed to make their music sound more imaginative and unique, at least to those who played and listened to it while under its sensorial influence. 

Although the analogy with color is dubious, there is a case to be made for the existence of "pure emotions." One piece of evidence comes from music. Malcolm Budd argues, for instance, that "when you hear music as being expressive of emotion E - when you hear E in the music - you hear the music sounding like the way E feels."19 Another piece of evidence is provided by the finding that the emotions can be produced by direct electric stimulation of the brain ... 

Once bronze came into use for cooking utensils it would soon be noticed that, upon being struck, the latter emitted a musical sound. The earliest bells would thus be cooking vessels used as gongs (p. 96). From these were evolved the bells and gongs known to the ancients. It was ultimately found that the best sounds could be obtained from alloys containing from 15 to 25 per cent of tin, the remainder being copper. 

For musical sounds, it is common to store Just a loop, or table, of the periodic component of a recorded sound waveform and play that loop back repeatedly. 

On playing music one reads a score, in which musical notes indicate acoustic frequencies. Therefore, characteristics of musical sounds are considered to be in the time evolution of acoustic frequency. Voss presented a paper at the First International Symoosium on 1//... 

Fluctuations, which was organized by the present author in Tokyo in 1977, that acoustic frequency fluctuations of musical sounds have in general a power spectral density which is approximately in inverse pro-...
