CD-DA：光盤數字音頻 (CD-DA: Compact Disc Digital Audio)

CD-DA is an abbreviation of "Compact Disc Digital Audio".

CD-DA是“光盤數字音頻”的縮寫 。

It is also known as Audio CD, is the established conventional format for audio compact discs. The data format of Compact Disc Digital Audio and all the substantial specifications and standards are stated in the Red Book. In 1980, the Red Book was issued and made available by Philips and Sony, which includes the collection of all the substantial specifications and add significant details about the format of Compact Discs. The format of CD-DA is the same as that which is used in ordinary CD players.

也稱為音頻CD ，是音頻光盤的常規格式。 光盤數字音頻的數據格式以及所有重要的規范和標準在《紅皮書》中都有說明。 1980年，飛利浦和索尼發行并提供了紅皮書，其中包括所有主要規格的集合，并增加了有關光盤格式的重要信息。 CD-DA的格式與普通CD播放機中使用的格式相同。

紅皮書格式：

In Red Book, the CD-DA format follows some specific standards which are common in the case of the entire CD formats.

在紅皮書中， CD-DA格式遵循某些特定標準，這些標準在整個CD格式中很常見。

數字音頻編碼規范

音頻格式 (Format of Audio)

In CD-DA format, the audio comprises two-channel signed to represent numbers in 16-bit linear PCM, which is sampled at 44,100 Hz.
在CD-DA格式中，音頻包括兩個通道的帶符號的代表16位線性PCM中的數字，以44,100 Hz采樣。
In case for purposes of encoding, audio samples are all signed 16-bit two's complement integer, which contains sample values from ?32768 to +32767.
為了進行編碼，音頻樣本都是帶符號的16位二進制補碼整數，其中包含從-32768到+32767的樣本值。

The frequencies specified by an audio CD can be up to 22.05 kHz, which is the Nyquist frequency sampled at the rate of 44.1 kHz.
音頻CD所指定的頻率可以高達22.05 kHz，這是以44.1 kHz的速率采樣的奈奎斯特頻率。
The format of data of audio is classified into frames, frames classified into twelve samples with six in left and six in right samples, discontinuous, which resulted in a sum of total 192 bits or 24 bytes of data of audio per frame.
音頻數據的格式分為幀，不連續的幀分為十二個樣本，左六個樣本，右六個樣本，這導致每幀總共192位或24字節的音頻數據。

音軌 (Tracks)

The major unit section on a CD is called a track.
CD上的主要單元部分稱為軌道。
A CD can comprise up to 99 tracks, which comprise a data track for mixed-mode discs.
CD最多可包含99個磁道，其中包括用于混合模式光盤的數據磁道。
Every track can sequentially have in order up to 100 indexes.
每個音軌可以依次具有多達100個索引。
The enormous greater section of songs is recorded under index 1, by taking the pre-gap being index 0.
通過將預間隙設為索引0，將歌曲的較大部分記錄在索引1下。
