NICAM (Near Instantaneous Companding Audio Multiplex) is a digital audio encoding system used in television broadcasting. It was developed to provide high-quality stereo audio alongside video signals, allowing for the transmission of multiple audio channels, including surround sound, alongside standard mono or stereo audio. NICAM was introduced in the 1980s and became widely adopted in Europe and other regions for broadcasting television.

The reflection phase change refers to the change in phase that occurs when a wave, such as a light wave or sound wave, reflects off a boundary or interface between two different media. This phenomenon is significant in fields like optics, acoustics, and telecommunications. The phase change that occurs upon reflection depends on the properties of the two media involved.

Sound symbolism refers to the idea that vocal sounds carry meanings that are not solely dependent on the conventions of language but are also related to the acoustic properties of the sounds themselves. This phenomenon suggests that certain sounds or phonetic features may be associated with specific meanings, emotions, or qualities, even across different languages.

The Speech Transmission Index (STI) is a quantitative measure used to assess the clarity and intelligibility of speech in a given acoustic environment. It is particularly important in fields such as acoustics, audio engineering, and telecommunications. The STI provides a standardized way to evaluate how well speech can be understood in different situations, such as in classrooms, auditoriums, or public spaces.

Stridulation is the act of producing sound by rubbing together certain body parts, often seen in various arthropods, such as crickets, grasshoppers, and some other insects. This process typically involves the scraping of a hardened part of the body (like wings or legs) against a rough surface. In crickets, for instance, the male rubs their wings together to produce a characteristic chirping sound, which is used primarily for attracting mates and establishing territory.

"Temp track" can refer to a couple of different contexts depending on the industry or field being discussed. Here are two common meanings: 1. **Film and Music Production**: In the context of film or television, a temp track (temporary track) is a placeholder piece of music used during the editing process. It helps convey the emotional tone of a scene and assists directors and editors in visualizing how the final score might feel.

The term "ceiling level" can refer to different concepts depending on the context in which it is used: 1. **Real Estate and Construction**: In architecture and construction, the ceiling level refers to the height of the ceiling in a room or space. This determines the vertical space available and can impact the design, acoustics, and lighting of the area.

Crosstalk refers to the phenomenon where a signal transmitted on one channel or circuit interferes with a signal on another channel or circuit. This can occur in various contexts, including telecommunications, audio systems, and electronic circuits. Here are a few key aspects of crosstalk: 1. **In Telecommunications**: In phone lines or data communication, crosstalk can happen when signals from one line leak into another, causing interference.

An acoustic radiometer is an instrument designed to measure the intensity of acoustic (sound) radiation. It typically quantifies sound pressure levels and can provide insights into the energy output of acoustic sources or the propagation of sound waves in various environments. Acoustic radiometers can be used in a range of applications, including: 1. **Environmental Monitoring**: Measuring noise pollution in urban areas or natural habitats. 2. **Scientific Research**: Studying sound propagation in different media, including water and air.

Soundboard recording refers to the technique of capturing audio directly from a soundboard or mixing console used during live performances, such as concerts, theaters, or events. This method allows for a higher-quality audio recording compared to capturing sound through microphones in the audience or venue, as it taps directly into the audio signals being processed by the mixer.

Delivered Audio Quality (DAQ) refers to the final quality of audio content as it is received by the listener, after all processing, encoding, and transmission have taken place. This concept is particularly relevant in fields such as broadcasting, streaming, and telecommunications, where audio signals are transmitted over various mediums and may undergo transformations that can affect their quality.

Disc Description Protocol (DDP) is a specification used in the context of audio mastering and disc production. It provides a standard framework for delivering audio content in a digital format to ensure that it can be accurately replicated on physical media like CDs, DVDs, or Blu-ray discs.

Fader creep is a term commonly used in the context of audio mixing and sound engineering. It refers to a phenomenon where the position of a mixer fader gradually drifts away from its intended setting due to mechanical wear, dust, or other factors. As a result, the output level may unintentionally change over time, leading to inconsistencies in sound levels during mixing or playback.

Gain staging is a crucial concept in audio engineering and music production that refers to the process of managing the signal levels throughout the audio signal chain. The primary goal of gain staging is to ensure that the audio signal maintains an optimal level, avoiding distortion or noise, while providing sufficient headroom for processing and overall mix clarity.

Half-speed mastering is a specialized audio mastering technique often used in the production of vinyl records. The process involves reducing the playback speed of the audio during the mastering stage to half of the normal speed (for example, if the normal speed is 33 1/3 RPM, it would be mastered at 16 2/3 RPM).

Krell Industries is a well-known manufacturer of high-end audio equipment, particularly focused on amplifiers, preamplifiers, digital sources, and loudspeakers. Founded in 1980 by Dan D'Agostino, the company is recognized for its commitment to high-quality sound reproduction and innovative engineering. Krell products are often praised for their performance and build quality, catering to audiophiles and enthusiasts who seek premium audio experiences.

Legacy Audio is a company known for designing and manufacturing high-end audio equipment, specifically loudspeakers and related audio components. Established in 1985 and based in the United States, Legacy Audio focuses on delivering high-fidelity sound reproduction through innovative design and engineering. Their products often integrate advanced technologies, such as multi-driver systems, proprietary drivers, and sophisticated cabinet designs, to achieve optimal sound quality and performance in various listening environments.

" Nevaton" does not appear to have a widely recognized definition or significance as of my last knowledge update in October 2023. It could refer to a specific term in a niche field, a brand, a product, or even a fictional character or concept, but without additional context, it's difficult to provide a precise answer.

Realistic is a brand that was historically known for its line of consumer electronics, particularly in the areas of radios, cassette players, and other audio equipment. It was primarily associated with the Tandy Corporation, which owned RadioShack. The Realistic brand was prominent during the 1970s and 1980s, offering affordable audio gadgets and electronics to consumers. Products under the Realistic brand were often recognized for their value, providing a combination of decent quality and affordability.

"Send Track" can refer to different concepts depending on the context. Here are a few possibilities: 1. **In Music Production**: In digital audio workstations (DAWs) like Ableton Live or Pro Tools, a "send track" typically refers to a track that is used to route audio to effects or buses.
