Sound speed profile. A sound speed profile shows the speed of sound in water at different vertical levels. It has two general representations: tabular form, with pairs of columns corresponding to ocean depth and the speed of sound at that depth, respectively. a plot of the speed of sound in the ocean as a function of depth, where the vertical ...
Rate Your Music. Rate Your Music (often abbreviated to RYM) is an online encyclopedia of music releases and films. Users can catalog items from their personal collection, review them, and assign ratings in a five-star rating system. The site also features community-based charts that track highest-rated releases.
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Acoustic analog recording is achieved by a ...
Time stretching is the process of changing the speed or duration of an audio signal without affecting its pitch. Pitch scaling is the opposite: the process of changing the pitch without affecting the speed. Pitch shift is pitch scaling implemented in an effects unit and intended for live performance. Pitch control is a simpler process which ...
Speed of sound. The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
An audio engineer with audio console, at a recording session at the Danish Broadcasting Corporation. An audio engineer (also known as a sound engineer or recording engineer) [1] [2] helps to produce a recording or a live performance, balancing and adjusting sound sources using equalization, dynamics processing and audio effects, mixing, reproduction, and reinforcement of sound.
While 1 atm (194 dB peak or 191 dB SPL) [11] [12] is the largest pressure variation an undistorted sound wave can have in Earth's atmosphere (i. e., if the thermodynamic properties of the air are disregarded; in reality, the sound waves become progressively non-linear starting over 150 dB), larger sound waves can be present in other atmospheres ...
Chroma feature. (a) Musical score of a C-major scale. (b) Chromagram obtained from the score. (c) Audio recording of the C-major scale played on a piano. (d) Chromagram obtained from the audio recording. In Western music, the term chroma feature or chromagram closely relates to twelve different pitch classes.
