Fifty Years of Artificial Reverberation

摘要: The first artificial reverberation algorithms were proposed in the early 1960s, and new, improved are published regularly. These have been widely used music production since 1970s, now find applications new fields, such as game audio. This overview article provides a unified review of various approaches to digital reverberation. three main categories delay networks, convolution-based algorithms, physical room models. Delay-network convolution techniques competing popularity technology field, often employed produce desired perceptual or artistic effect. In including virtual reality, predictive acoustic modeling, computer-aided design spaces, accuracy is desired, models mainly used, although, due their computational complexity, they currently for simplified geometries generate impulse responses use with method. With increase computing power, all these will be available real time. A recent trend audio emulation analog units, spring reverberators, using signal processing algorithms. As case study we present an parametric model unit.
