What does vr stand for in audio

OT is the original song op: (opening) that is, the title song / theme song ED: the end song track: track, track (can also be abbreviated as trk) bgm: (back ground music) background music, in the course of the drama to be used, generally included in the ost. ユレクション collection: an anthology, also known as a collection. A cd can be a collection of the same series, or a collection of different series, most of which are the so-called "best of the best". collection has the best collection, themes collection, single collection, directors collection and so on, The best collection, themes collection, single collection, directors collection, etc. ィメ-ジ-アルバム image album: impression of the collection, different from the post, in which the music is not a faithful reproduction of the music in the original play, but through the original work with a somewhat different way of the original song will be played out in order to constitute a relatively independent track (more suitable for occasions such as concert performance). It gives the impression of the original song. image song: impression song, basically the same as above, but this one is a single mix/remix: a remixed version of a song or an album of remixes. A bit different from an impression set, a remix is a re-edit of the music based on the post, with vocals, ambient sound effects, or a variety of other things added in order to achieve a better or different effect than the post, which gives it a very cool feel! A tune that sounds dull and gray in the anime can be a very powerful dance song in the remix version! live: live recording disk, generally live concerts, you can feel the effect of actually attending the concert. vocal: someone's voice, not pure music tape, generally refers to the song. drama: similar to radio drama, that is, with a group of voice actors to perform, but generally are quite with the standard. theme songs: theme songs, usually the most famous songs in the series. bonu track: a special track attached to a CD SINGLE CD: a CD with only one or two songs, or two or three songs, and much cheaper than a regular CD Single CDs are usually small, 8cm in size (anime single CDs don't use 8cm CDs anymore), and cost around 1,000 yen, with 4-6 songs, including Instrumental, so you can count on them. Instrumental is included, so it's the same price as buying an album. ...... by DARK-YY) Many singers release singles before releasing their albums to ensure that their songs and singers are popular/tested... Or not enough to put together an Album (according to MasterKang's suggestion) vocal book: audio cd book. It's like watching a vcd with the screen off. sm: shomei trading co. Seems to be a main Japanese imported animation cd company, the current domestic no matter which version of the d version or z version of this kind of cd are from this company. (The original smcd also seems to be expensive) cd number: a long time, you will find these animation cd will have a gggg\a&g\ga\gm and so on the logo, each logo corresponds to a cd, not the same as each other, if a cd can not find the corresponding cd number, is the unofficial release of the cd. may be a version of d version of the d version of the quality of the more doubtful, it is recommended that everyone! Don't buy this kind of cd. cv：character voice Voice actor, the voice of an animated character. ost: original sound track (original soundtrack), i.e., the original sound album, usually contains the soundtrack, theme song, etc. of the work (animation, movie etc...). The soundtrack and theme song of the work (animation, movie, etc...) are generally included. ova：original video animatin (also called oav), direct release of the video version of the work, not first in the theater or television screening. ---------------------------------------------------------------------------------------------------------------------------------- ---------- cd: Sony and Philips jointly developed a digital music CD-ROM, 12cm diameter and 8cm diameter two specifications, the former is the most common, it can provide 74 minutes of high-quality music. md: mini-recordable music CD developed by Sony, the appearance of the computer like a 3.5-inch floppy disk, but the use of optical signal pickup system, similar to the cd. md uses highly efficient compression technology to achieve the same recording time with the cd, the quality of the sound is close to the cd. atrac: a compression technology of md, which is based on the heart of the principle of acoustics, the human ear is unable to distinguish between the intensity of sound signals, the direction, pitch, timbre rounded off, tone, timbre rounding off, so as to store high-quality music on a md blank disk with a small capacity. Conceptually, this compression is more scientific than mp3. dvd-audio: is by the dvd forum audio working group (wg-4) and the inter******** steering committee (isc; for a day, the United States, Europe's recording association) *** with the development of specifications, but also dvd family in an important part. It is also an important part of the dvd family. Compared to dvd-video's compressed 16-bit, 48khz sampling frequency, dvd-audio's six-channel sound is crisper, reaching the potential of 24-bit, 96khz sampling, and even the hard-of-hearing can tell the difference between the two, but both formats are far superior to the flat 16-bit, 44.1khz sound of CDs. Since the format supported by dvd-audio is clearly of higher quality than the pcm (pulse coded modulation) music of dvd-video and cd, it is capable of richer 3d surround sound, with a dynamic frequency range four times greater than that of cd. sacd: abbreviation of super audio cd, is Sony and Philips in their joint development of mmcd (single-sided double-layer structure of the high-density optical disk) based on the development of the introduction of the new digital audio format. sacd adopts the name of dsd (direct stream digital, direct stream digital coding) of the new coding method, the information storage for the ordinary cd 6 times. sacd with a high quality of up to 3d surround sound effect, its dynamic frequency range is four times larger than cd. Sacd to up to 2.8224mhz sampling frequency (for cd44.1khz 6 times) to the original analog audio signals quantized into 1bit digital audio signals, when restored to analog audio signals replayed, the restoration of the waveforms and the original music analog waveforms are almost no difference than cd (44.1khz/16bit) or dvd audio ( 96khz/24bit), and the original analog waveforms. 96khz/24bit) is more complete than cd (44.1khz/16bit) or dvd audio (96khz/24bit). As a result, its sound clarity and signal-to-noise ratio are very high, with a dynamic range of 120db in the 20-20khz frequency range. sacd capacity is the same as dvd-audio, which is 4.7gb. ------------------------------------------------------------ -------------------------------------------------------------------------------- Bitstreaming: a Philips technology for converting cd digital signals to analog music signals. Bitrate: another reference indicator of the efficiency of digital music compression, it indicates the average bit value needed to record audio data per second (bit is the smallest unit of data in a computer, it refers to a number of 0s or 1s), usually we use kbps (commonly known as 1000 bits per second) as the unit. cd's bitrate for digital music is 1411.2kbps (which means that it takes 1 second of cd's music to be recorded). The bit rate of digital music in cd is 1411.2kbps (that is to say, to record 1 second of cd music, you need 1411.2×1024 bits of data), and the bit rate of mp3 digital music, which is nearly the same as the sound quality of cd, needs to be about 112kbps～128kbps. Encoding: to convert it into a file of another format by compressing the file. Decoding: Converting a compressed file into another format by decompressing it. Sampling Rate: The process of converting analog audio to digital audio is called sampling, which simply means how many data are needed to record a 1-second-long sound by sampling the waveform. 44khz sampling rate means that 44000 data are needed to describe a 1-second-long sound waveform. In principle, the higher the sampling rate, the better the quality of the sound. Dolby Surround: A type of sound that encodes a rear effect channel into a stereo channel. Playback requires a decoder to separate the surround signal from the encoded sound. Quantization level: Simply put, it is the number of bits of binary data that describes the waveform of a sound, usually in bits, such as 16bit, 24bit. 16bit quantization level records the data of a sound as a 16-bit binary number, and therefore, the quantization level is an important indicator of the quality of digital sound. When we describe the quality of digital sound, we usually describe it as 24bit (quantization level), 48khz sampling, for example, the quality of standard cd music is 16bit, 44.1khz sampling. Compression ratio: usually refers to the ratio of the size of a music file before and after compression, and is used to simply describe the compression efficiency of digital sound. a3d (a3d 1.0): a3d is a 3d sound technology introduced by aureal, which utilizes the principle of hrtf as mentioned before, to achieve the standard of 3d sound through the output of the two speakers. At the beginning, a 3d specifications only aureal launched the vortex generation chip support, and then because of this specification of 3d sound positioning is quite good, coupled with only two-channel speakers can be simulated 3d sound, so later many non-vortex chipset will be included in this specification. (a3d 2.0) a3d2.0 is a new audio specification released by aureal when they launched the vortex II chipset, and the biggest difference with version 1.0 is the improved resolution of the sound. It is compatible with ds3d, and with the unique "wavetracing" sound wave tracking function, it can more realistically present the environmental sound effects, but at present only the vortex 2 au8830 chip can fully support this specification. directsound 3d: directsound 3d is introduced by microsoft, it uses the sound size of the proportional adjustment and dubler effect, to achieve the software to simulate the effect of 3d sound. Any application can get the desired effect by using it with a sound card that supports directsound 3d. Since this was developed by many sound card manufacturers in conjunction with Microsoft***, most sound cards now support this technology. hdcd: advanced audio coding technology, recording audio data in a patented way, the depth and level of detail, as in a professional recording studio level, realistic and detailed. hdcd is coded at a speed of 20-bits, which is more expressive of the layers of acoustic effects than the general 16-bit coding of cd's. Not only does it allow the sound to express its proximity to the distance, but it also makes the acoustic portion of the sound and pure music appear more natural and clearer. The sound is not only more distant, but also more natural and clearer in acoustic parts and pure music. With hdcd decoding and precise filtering, the sd-k330 can not only read hdcd disks, but also enrich the sound quality when playing normal cds. vbr: The full name is variable bitrate, which is dynamic bit rate. And the traditional cbr encoding of mp3 is different, the traditional cbr (constents bitrate) is static bitrate, cbr agreed on the sampling rate of mp3 for a fixed value. An mp3 is compressed from start to finish at a fixed value such as 128kbit/s. The vbr, on the other hand, takes a completely new approach to compression, with dynamic adjustment techniques throughout. When in the bass section, vbr will automatically use a lower bit rate such as 32kbit/s to compress the sound quality; when in the treble section will use a higher bit rate such as 224kbit/s to compress the sound quality; when in the high end of the level is the highest level of compression of 320kbit/s. vbr mp3 is in the case of controlling the size of the file, to maximize the quality of the mp3 sound - ---------------------------------------------------------------------------------------------------------------------------------- --------- mp3: invented by a German research institute, currently generally refers to a format for compressing and storing music files on a computer. mp3 is an abbreviation for the technical term, that is, mpeg-1 audiolayer-3, I believe that the term mpeg is not unfamiliar to everyone, it is moving picture exp-erts group's abbreviation, that is, moving picture compression processing group's meaning, we see the vcd is the use of mpeg-1 technology, and dvd is the use of further mpeg-2 technology. mp3 is a technology branch of mpeg, mainly used to compress sound. A **** divided into three levels (layer), respectively, layer-1 (mp1), layer-2 (mp2), r-laye3 (mp3). cddb: database with artist, album name and song title in memory. id3: the label of the mp3 file, which indicates the title and author of the mp3 file (song). srs wow: a sound quality enhancement technology developed by srs labs for the new generation of audio formats such as mp3. This technology is based on the principles of physiological acoustics and psychoacoustics of the human ear, and digs deep into the three-dimensional surround information in stereo audio, which can significantly expand the width, height and depth of the sound field, making the sound more natural, pleasant to the ear, and not easy to fatigue after a long time of listening. Moreover, it will srs trubass bass enhancement technology into it, can produce more deep, thick, elastic bass, in the volume of smaller multimedia speakers playback produced by the bass effect can be almost comparable to the big speakers. The range of the virtual sound field it produces is much larger than the range of the sound field produced by the speakers themselves, and accordingly, the range of the optimal listening area is also much larger. mp3pro: utilizes the codec enhancement technology developed by coding technologies and the mp3 technology developed by thomson and fraunhofer *** together. When creating an mp3pro file, the encoder divides the audio into two parts. One part is the audio data in the German low-frequency part of the separation, through the traditional mp3 technology and encoding of the normal mp3 audio stream, which allows the mp3 encoder can focus on low-frequency signals to obtain better compression quality, and the original mp3 player can also play mp3pro files. The other part is to encode and embed the separated high-frequency signals into the mp3 stream, which traditional mp3 players ignore, while the new mp3pro player can restore the high-frequency signals and combine the two to get high-quality, full-bandwidth sound. With this technology, mp3pro can provide the same quality as 128kbps mp3 at 64kbps encoding rate. ---------------------------------------------------------------------------------------------------------------------------------- ---------- vqf: actually refers to twinvq (transform-domain weighted interleave vector quantization), an audio compression technique developed by ntt human interface laboratories, a division of the nippon telegraph and telephone group. interface laboratories of the ntt (nippon telegraph and telephone) group in Japan. The technology is supported by the famous yamaha company. vqf is its file extension. Simply put, it is similar to mp3 in that it uses a distortion algorithm to compress sound, but it is fundamentally different from mp3 compression: vqf is designed to compress music, not sound, and therefore uses a technique known as "vectorization" or "quantization. Therefore, vqf uses a compression technique called "vectorization". This technology first vectorizes the audio data, then unifies and smoothes the similar waveforms in the audio waveform, and strengthens the sensitive part of the human ear, and finally scalarizes the processed vector data and then compresses it. asf, asx, wma, wax, etc.: asf and wma are the new generation of online streaming digital audio compression technology developed by Microsoft for real companies. This compression technology is characterized by both fidelity and network transmission needs, so it has a certain degree of sophistication. Also due to the influence of Microsoft, this audio format is now gaining more and more support. ogg: ogg vorbis is a new audio compression format similar to existing music formats such as mp3. One difference is that it is completely free, open and patent-free. vorbis is the name of this audio compression mechanism, while ogg is the name of a program that intends to design a completely open multimedia system. Currently, only the oggvorbis part of the project has been realized. ogg vorbis files have the extension .ogg. the format in which the files are designed is very advanced. An ogg file created now can be played on any player in the future, so this file format can be constantly improved in size and sound quality without affecting older encoders or players. For music fans, the significant benefit of using ogg files is the superior sound quality that can be achieved with smaller files. Also, since ogg is completely open and free, making ogg files will not be subject to any patent restrictions, and a large number of encoders and players can be expected to be available. This is also the reason why there are so few mp3 encoders nowadays and most of them are commercial software, because fraunhofer charges royalties. aac: (advanced audio coding) This is a music file format based on mp3, which has a wider frequency range than mp3, 8-96khz, and a compression ratio roughly the same as mp3. However, aac is not as popular as mp3 because not many manufacturers support this compression standard, and software to create this file format is not common. ---------------------------------------------------------------------------------------------------------------------------------- ---------- eax：eax全名environmental audio extension，这是创新公司在推出sb live sound card launched by the api slot standard, mainly for some specific environments, such as concert halls, corridors, rooms, caves, etc., for sound effects, when the computer needs special sound effects, you can through the When the computer needs special sound effects, it can be processed through directx and the driver to let the sound card, which can show the reaction of different sounds in different environments, and achieve three-dimensional sound effects by means of multi-piece speakers. eax was 1.0 when it was first introduced, and is currently 2.0, and many games are now supporting this specification. pv: projection video, that is, music video. It is a mistake to refer to music television as mtv. mtv is a trademark, the name of an American television station. Music TV is their invention. When the concept was introduced in mainland China, it is against trademark law to use the trademark mtv to refer to the common name of music television. So, if you can, don't use mtv to refer to music TV, use pv is better. vr: visual rock, I want to see this word can also understand a rough it ---- visual rock, this kind of music began in Japan, usually with gorgeous clothing, personality modeling appearance, the style of music is also very dark, visual rock ancestor is x-japan, the prototype of this music is supposed to be gorgeous gothic rock, such as kiss and other western bands. The originator of visual rock is x-japan, which is supposed to be glam gothic rock, like kiss and other western bands. indies band: an underground band, not signed to a major record label. Generally, indies band's promotion and styling are handled by the band members. dt: demo tape maxi: maxi single, usually consisting of three or four songs cw or c/w: coupling with, the name of the song that accompanies the single cd, the single usually has a cw, usually refers to the b-side of the single first edition special: sometimes in the first edition there will be a few postcards, special albums, or even posters. The first edition special: sometimes the first edition will be presented with some postcards, special albums, and even posters. They are all treasures that fans collect.

More than a few years ago, Morin Hari stabilized the album and moved it to a classified classroom

The first edition of the album was a classified classified classroom album.
