To describe sound fields in acoustics, the sound pressure p, measured in Pascals (Pa), is widely used. As with electrical quantities in sound engineering, it is usually more convenient to use a logarithmic scale here. At the same time, the concept of sound pressure level (SPL) is introduced L = 20 log (p / p0), where p0 = 2 x 10-5 Pa is the sound pressure at the threshold of audibility. Very often, ultrasound is measured (or calculated) in separate frequency bands. The most widespread are octave or 1/3 octave bands with a relatively constant bandwidth. Geometrical average (below in the text for brevity, average) frequencies of these bands are regulated by international and domestic standards. A preferred range of mid frequencies for octave bands: … 125, 250, 500, … Hz; for 1/3 octave bands: … 125, 160,200, 250, … Hz. In addition to these narrow frequency bands, broadband correction is also applied, the form of which is Continue reading
Many musicians and sound engineers underestimate the capabilities of modern computers.
Many musicians and sound engineers underestimate the capabilities of modern computers, music applications, and inexpensive sound cards. At the mention of such a technique, they scornfully purs their lips and pronounce a word in which all their contempt for the world of mere mortals is concentrated: “multimedia” … However, acquaintance with Western periodical music publications suggests that the entire civilized world has long turned to face low-budget technologies: articles are written on this topic, the advantages and disadvantages of various programs are discussed, and serious people like Eric Persing (owner of Spectrasonics and creator of the entire library of sounds for Rola synthesizers nd) put the first experiments on the use of software synthesizers in serious budget projects. And the prices of programs and plug-ins make you think. For example, a set of Waves Native Gold Bundle plug-ins costs as much as $ Continue reading
