The dynamic range of a direct-cut vinyl record may surpass 70 dB. Analog studio master tapes can have a dynamic range of up to 77 dB. [5] An LP made out of perfect diamond has an atomic feature size of about 0.5 nanometer, which, with a groove size of 8 micron, yields a theoretical dynamic range of 110 dB. An LP made out of perfect vinyl LP ...
Dynamic range (abbreviated DR, DNR, [ 1] or DYR[ 2]) is the ratio between the largest and smallest values that a certain quantity can assume. It is often used in the context of signals, like sound and light. It is measured either as a ratio or as a base-10 ( decibel) or base-2 (doublings, bits or stops) logarithmic value of the ratio between ...

XDR (audio) XDR ( expanded dynamic range ), also known as SDR ( super dynamic range) is a quality-control and duplication process for the mass-production of pre-recorded audio cassettes. It is a process designed to provide higher quality audio on pre-recorded cassettes by checking the sound quality at all stages of the tape duplication process.
Other concurrent advances in audio technology led to the introduction of a range of new consumer audio formats and devices, on both disc and tape, including the development full-frequency-range disc reproduction, the change from shellac to polyvinyl plastic for disc manufacture, the invention of the 33rpm, 12-inch long-playing (LP) disc and the ...
DVD-Audio. DVD-Audio (commonly abbreviated as DVD-A) is a digital format for delivering high-fidelity audio content on a DVD. DVD-Audio uses most of the storage on the disc for high-quality audio and is not intended to be a video delivery format. The standard was published in March 1999 [ 3] and the first discs entered the marketplace in 2000.
Audio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample.
We poked around eBay to see how much some DVDs are going for, and you'll probably be surprised by which ones are asking for quite a large sum. Check out the slideshow above to learn which DVD ...
