OT refers to the original song
op: (opening) is the opening song/theme song
ED: Ending song
track: Track, audio track (can also be abbreviated as trk)
bgm: (back ground music) background music, used in the process of drama, is generally included in ost.
ユレクション collection: a selection, also known as a collection. A CD can contain selections from the same series or different series. Most of them contain the so-called "essence". Collections include best collection, themes collection, single collection, directors collection, etc.
ィメ－ジ?アルバムimage album: Impression album, different from ost, the songs in it are not faithful reproductions of the music in the original play, but are the original songs in a slightly different way from the original work. Play it out to form a relatively independent piece of music (more suitable for occasions like concert performance). It gives the impression that it is the original song.
image song: impression song, basically the same as above, but this is a single
mix/remix: a remixed version of a song or a remixed album. It is a little different from the impression album. The remixed version of the music is re-edited on the basis of OST, and vocals, environmental sound effects or other various things are added in order to achieve a better or different effect from OST. , it feels very cool! A song that sounds dull and dark in the animation may be a very exciting dance song in the remix version!
Live: A live recording disc, usually from a live concert, where you can feel the effect of actually participating in the concert.
Vocal: With vocals, not pure music, generally refers to songs.
Drama: Similar to a radio drama, it is performed by a group of voice actors, but it is usually of a very high standard.
Theme songs: theme songs, usually the most famous songs in the series.
bonu track: a special additional audio track after the CD
SINGLE CD is a CD (single) with only one or two songs or two or three songs, and the price is cheaper than ordinary CDs. many. Single CDs are generally thin discs, only 8cm in size (Single CDs for anime no longer use 8CM CDs. The price is around 1,000 yen. It contains 4 to 6 songs, including Instrumental, so the price is the same as buying an album. People who buy it Quite a few... by DARK-YY) Many singers will release singles before releasing albums to ensure the popularity/testing of their songs and singers...or they may not be able to make up an Album (according to MasterKang's suggestion)
Vocal book: Audio CD book. It's like turning off the screen and watching a VCD.
sm: Shengmei Trading Co., Ltd. It seems to be a company that specializes in animation CDs imported from Japan. At present, no matter which version of the D version or Z version of such CDs in China, they all come from this company. (The original smcd seems to be expensive)
CD number: Over time, you will find that these animation CDs will have a logo like ggg\a&g\ga\gm, each logo corresponds to a The CDs are different from each other. If the corresponding CD number cannot be found for a CD, it is an unofficial CD. It may be the d version of the d version, but the quality is more questionable. I suggest you not buy this type of CD.
cv: character voice voice actor, voice actor of animated characters.
ost: original sound track (original sound track), that is, the original sound track of the work, which generally includes works (animation, movies, etc. ...) soundtrack, theme song, etc.
OVA: original video animatin (also called OAV), a work that is released directly to video without first being shown in theaters or on television.

cd: A type of CD jointly developed by Sony and Philips Digital music discs are available in two specifications: 12cm diameter and 8cm diameter. The former is the most common and can provide 74 minutes of high-quality music.
md: A mini recordable music disc developed by Sony. It looks like a 3.5-inch floppy disk for computers, but uses an optical signal pickup system, similar to a CD. MD uses efficient compression technology to achieve the same recording time as CD, and the sound quality is close to CD.
ATRAC: A compression technology of MD. It is based on the principle of psychoacoustics and discards the intensity, direction, pitch, and timbre of sound signals that cannot be distinguished by the human ear, thereby compressing a file with a small capacity. Store high quality music on md blank discs. Conceptually, this compression method is more scientific than mp3.
dvd-audio: It is composed of dvd forum audio working group (wg-4) and inter******** steering committee (isc; a recording association for Japan, the United States and Europe)* **The specifications formulated at the same time are also an important part of the DVD family. Compared with the 16-bit, 48khz sampling frequency music compressed by DVD-Video, the six channels of DVD-Audio are crisper and can reach the potential of 24-bit, 96khz sampling music, even for people with poor hearing. Distinguish the difference between the two, but both formats are far beyond the CD tablet, 16-bit, 44.1khz sound. Since the format supported by dvd-audio is obviously of higher quality than the PCM (pulse coded modulation) music of dvd-video and cd, it can express richer 3d surround sound effects, and its dynamic frequency The range is four times larger than that of CD.
SACD: The abbreviation of Super Audio CD is a new digital audio format developed and launched by Sony and Philips based on the mmcd (single-sided double-layer structure high-density optical disc) jointly developed by them. SACD adopts a new encoding method called DSD (direct stream digital, direct digital stream coding), and the information storage capacity is 6 times that of ordinary CDs. SACD quantizes the original analog audio signal into a 1-bit digital audio signal at a sampling frequency of up to 2.8224mhz (6 times that of CD44.1khz). When it is restored to an analog audio signal and replayed, the restored waveform is the same as the simulation of the original music. The waveforms are almost identical and more complete than those of CD (44.1khz/16bit) or DVD audio (96khz/24bit). Therefore, its sound clarity and signal-to-noise ratio are very high, and its dynamic range reaches 120db in the frequency range of 20-20khz. The capacity of sacd is the same as that of dvd-audio, both are 4.7gb.

Bitstream: A technology from Philips that converts CD digital signals into analog music signals.
Bit rate: It is another reference indicator of digital music compression efficiency, indicating the average bit value required to record audio data per second (a bit is the smallest data unit in a computer, referring to a 0 or The number of 1), usually we use kbps (in layman's terms, 1000 bits per second) as the unit. The bit rate of digital music in CD is 1411.2kbps (that is, recording 1 second of CD music requires 1411.2×1024 bits of data). The bit rate required for mp3 digital music that is close to CD sound quality is about 112kbps to 128kbps.
Encoding: Convert a file into another format by compressing it.
Decoding: Converting a file into another format by decompressing it.
Sampling rate: The process of converting analog audio into digital audio is called sampling. Simply put, it is how much data is needed to record 1 second of sound through waveform sampling. Sound with a 44khz sampling rate takes 44,000 data to describe the sound waveform for 1 second. In principle, the higher the sampling rate, the better the quality of the sound.
Dolby surround: A sound that encodes rear effects channels into stereo channels. Playback requires a decoder to separate the surround signal from the encoded sound.
Quantization level: Simply put, it refers to how many bits of binary data the data describing the sound waveform is, usually using bit as the unit, such as 16bit, 24bit. The 16-bit quantization level records sound data using 16-bit binary numbers. Therefore, the quantization level is also an important indicator of digital sound quality. 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 music files before compression and after compression. It is used to simply describe the compression efficiency of digital sound.
a3d (a3d 1.0): a3d is a 3D sound effect technology launched by aureal. It uses the previously mentioned hrtf principle to achieve 3D sound effect standards through the output of two speakers. At the beginning, the A 3D specification was only supported by the Vortex generation chip launched by Aureal. Later, due to the good positioning of 3D sound effects of this specification, and the fact that only two-channel speakers can simulate 3D sound effects, many non-Vortex chips later The chipset also incorporates this specification. (a3d 2.0) a3d2.0 is a new sound effect specification released by aureal when it launched the Vortex second-generation chip. The biggest difference from version 1.0 is the improved sound resolution. It is compatible with DS3D, and has a unique "wavetracing" sound wave tracking function that can more realistically present environmental sound effects. However, currently only the Vortex 2 AU8830 chip can fully support this specification.
Directsound 3d: Directsound 3d is launched by Microsoft. It uses the ratio adjustment of sound size and the Doppler effect to achieve the effect of simulating 3D sound effects with software. Any application can obtain the desired effect through it and a sound card that supports DirectSound 3D. Since this is developed jointly by many sound card manufacturers and Microsoft, most sound cards now support this technology.
hdcd: Advanced audio coding technology uses a patented method to record audio data. Its depth and detail are just like those in a professional recording studio, lifelike and delicate. HDCD uses a 20-bit encoding speed, which is better than CDs compiled with 16-bits. It can express the layering of sound effects better. It not only allows the sound to express its distance, but also makes the vocal part and pure music appear more natural. And clear. Through HDCD decoding and precise filters, the SD-K330 can not only read HDCD discs, but also enrich its playback sound quality when playing ordinary CDs.
vbr: The full name is variable bitrate, which is dynamic bitrate. Different from traditional CBR encoded MP3, traditional CBR (constents bitrate) is a static bit rate. CBR agrees that the sampling rate of MP3 is a fixed value.
An mp3 is compressed to a fixed value such as 128kbit/s from beginning to end. VBR adopts a brand new compression method with full dynamic adjustment technology. 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 high band section, it will use a higher bit rate such as 224kbit/s to compress the sound quality; when in the high-end section Then use up to 320kbit/s for compression. vbr mp3 maximizes the sound quality of mp3 while controlling the file size

mp3: Invented by a German research institution, it currently generally refers to a format for compressing and storing music files on computers. MP3 is the abbreviation of a technical term, which is the abbreviation of mpeg-1 audiolayer-3. I believe that everyone is familiar with the term mpeg. It is the abbreviation of moving picture exp-erts group, which means moving image compression processing group. As you can see The vcd you get uses mpeg-1 technology, while the dvd uses the further mpeg-2 technology.
mp3 is a technology branch in mpeg, mainly used to compress sound. A *** is divided into three levels (layers), namely layer-1 (mp1), layer-2 (mp2), and r-laye3 (mp3).
cddb: A database with singers, album names and song titles in memory.
id3: The tag of the mp3 file, indicating the title and author of the mp3 file (song).
srs wow: It is a sound quality enhancement technology developed by srs labs for new generation audio formats such as mp3. This technology is based on the physiological acoustics and psychoacoustic principles of the human ear, and deeply explores the three-dimensional surround information in stereo speakers. It can significantly expand the width, height and depth of the sound field, making the sound more natural and pleasant, and less fatigued after listening for a long time. Moreover, it also incorporates SRS's trubass bass enhancement technology, which can produce deeper, richer, and more elastic bass. When played back with a smaller multimedia speaker, the bass effect produced is almost comparable to that of a large speaker. The range of the virtual sound field it generates is much larger than the range of the sound field generated by the speaker itself. Correspondingly, the range of the best listening area is also much larger.
mp3pro: It uses the codec enhancement technology developed by coding technologies and the mp3 technology jointly developed by Thomson and Fraunhofer ***. When making an mp3pro file, the encoder splits the audio into two parts. Part of it is to separate the low-frequency part of the audio data and encode it through traditional mp3 technology to obtain a normal mp3 audio stream. This allows the mp3 encoder to focus on the low-frequency signal and obtain better compression quality. , and the original mp3 player can also play mp3pro files. The other part is to encode the separated high-frequency signal and embed it into the mp3 stream. Traditional mp3 players will ignore it, while the new mp3pro player can restore the high-frequency signal and combine the two. Combine for high-quality, full-bandwidth sound. Through this technology, mp3pro can provide the same quality as 128kbps mp3 at a 64kbps encoding rate.

vqf: Actually refers to twinvq (transform-domain weighted interleave vector quantization), which is an audio compression technology developed by ntt human interface laboratories under Japan's ntt (nippon telegraph and telephone) group. This technology is supported by the famous Yamaha company. vqf is the extension of its file. Simply put, it is similar to the implementation method of mp3. They both use distortion algorithms to compress sounds. However, it is fundamentally different from mp3 compression technology: the purpose of vqf is to compress music rather than Sound is compressed, so vqf uses a compression technology called "vector quantization". This technology first vectorizes the audio data, then unifies and smoothes similar waveform parts in the audio waveform, and emphasizes the parts that are sensitive to the human ear. Finally, the processed vector data is scalarized and compressed.
asf, asx, wma, wax, etc.:
asf and wma are new generation online streaming digital audio compression technologies developed by Microsoft for real companies. The characteristic of this compression technology is that it takes into account both fidelity and network transmission requirements, so it has a certain degree of advancement. Also due to Microsoft's influence, 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. But one thing is different: it is completely free, open and patent-free. Vorbis is the name of this audio compression mechanism, and ogg is the name of a project that intends to design a completely open multimedia system. Currently, only the oggvorbis part of the plan has been implemented. The extension of ogg vorbis file is .ogg. The design format of this file is very advanced. Ogg files created now can be played on any player in the future, so the file format can continue to improve in size and sound quality without affecting older encoders or players.
For music fans, the significant benefit of using ogg files is that they can obtain superior sound quality with smaller files. Moreover, since ogg is completely open and free, the production of ogg files will not be subject to any patent restrictions, and it is expected that a large number of encoders and players will 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 developed based on mp3. Its frequency range is wider than mp3, reaching 8-96khz, and the compression ratio is Much the same as mp3. However, because there are not many manufacturers that support this compression standard, and the software for producing this file format is not common, aac is not as popular as mp3.

eax: The full name of eax is environmental audio extension. This is the API slot standard introduced by Innovation Company when it launched the sb live sound card. It is mainly aimed at some specific environments, such as concert halls, corridors, rooms, caves, etc. Create a sound effector. When the computer needs special sound effects, it can be processed by the sound card through directx and drivers. It can show the reactions of different sounds in different environments, and achieve three-dimensional sound effects through multi-piece speakers. eax was version 1.0 when it was first launched, and is currently version 2.0, and many games currently support this specification.
pv: promotion video, music video.
It is actually wrong to call music television mtv. mtv is a trademark and the name of an American television station. Music television was their invention. When mainland China introduced this concept, it used the trademark mtv to refer to music television as a general name, which actually violated trademark law. Therefore, if possible, do not use mtv to refer to music television, it is better to use pv.
vr: visual rock, I think I can get a general idea when I see this word - visual rock, this kind of music started in Japan, usually with gorgeous clothes and unique styles. , the music style is also very dark. The originator of visual rock is x-japan. The prototype of this music should be glam goth rock, Western bands such as Kiss.
jrock: Japanese rock, generally refers to Japanese rock music.
indies band: underground band, a band without major record signings. Generally, the promotion and styling of indies bands are all done by the band members.
dt: demo tape, trial tape
maxi: maxi single, generally includes three to four songs
cw or c/w: coupling with, yes Along with the title of the attached song of a single CD, the single usually has a cw, generally referring to the b-side song of the single
First release bonus: Sometimes some postcards, special albums, and even posters will be given in the first edition wait. They are all treasures collected by fans.
