audio music video search
Fidelity evaluation is a long-standing issue with audio systems in general and introduction of lossy compression algorithms and psychoacoustic models has only increased debate. You can do Audio Video Music Search and Play on the PlayAudioVideo search engine. Audio can be measured and analyzed more precisely than can be done manually by listening to the content, but what this technical measurement and analysis lacks is the ability to determine if it sounds "good" or "bad" to any given listener. Much more, including Audio Music Search and Play and images on the PlayAudioVideo search engine.
Commercial digital recording of classical and jazz music began in the early 1970s, pioneered by Japanese companies such as Denon, the BBC, and British record label Decca (who in the mid-70s developed digital audio recorders of their own design for mastering of their albums), although experimental recordings exist from the 1960s. Video Search and Play is easily done on the PlayAudioVideo search engine. The first 16-bit PCM recording in the United States was made by Thomas Stockham at the Santa Fe Opera in 1976 on a Soundstream recorder. In most cases there was no mixing stage involved; a stereo digital recording was made and used unaltered as the master tape for subsequent commercial release. These unmixed digital recordings are still described as DDD since the technology involved is purely digital. (Unmixed analogue recordings are likewise usually described as ADD to denote a single generation of analogue recording.)
