There is additional information that is not stored as files that your computer can see and that is specified by the standards for CDs. The standard states that a CD drive must recognize this information and read the data files based on the information it contains. How do the 700MB CD-R discs you buy in stores claim that you can store 80 minutes of CDA audio on them if more than 10MB per minute of audio is needed? The truth is that the capacity of a 700 MB disk is actually much higher (more than 804 MB), but the extra 14.915% of the capacity is used through the error correction code used to compensate for scratches and marks on the disks. This error correction area is essential on data disks where a single bit of erroneous data could corrupt the entire file. However, on audio CDs, this error correction area can be used as additional memory because the errors in the audio file are only displayed as minor sound errors that would probably not be noticed by human ears and would not crash the CD player or computer on which it was played. It may be possible to use other formats if your CD burning software supports them, but they may not offer the best quality or they may not be playable on all CD drives. CDA files can only be played from a CD and the files must be converted to WAV, MP3 or similar FILES to store on a computer hard drive or DVD. The CDA format is an industry standard (called the Red Book audio standard) used to encode music on CD, and audio CDs purchased on the main street use this format. If you`ve converted tape or vinyl to digital format, I wouldn`t expect a noticeable quality advantage when converting to .wav format over a low-loss .mp3. To be playable in any CD drive, you must burn to Audio CD Format (CD-DA). This is not the same as a data CD with a file system (iso9660) where music (mp3 or other) can be represented as files. The audio CD format has no file system or file format, the music is simply located directly on the CD in RAW format track by track. It is also theoretically possible to burn CD-R discs with “90 minutes” (790 MB) or “99 minutes” (870 MB).
However, there is no guarantee that your CD burner will accept these CD-R discs or that your CD drive will read anything other than a 650MB Red Book Standard disc that burns with 74 minutes of audio. First, let`s look at the two different formats. Audio CDs are designed for one purpose: audio. They contain raw, uncompressed data in a very fixed format: 44,000 samples per second, each sample consisting of a number of 16 bits (2 bytes) for each of the right and left channels. I see in the comments that have already been posted that many, probably well-informed, people are talking about CD players capable of playing music with a .cda extension. Well, I understand that .cda is just a shortcut and contains indexing information and no audio at all. You can easily prove this by hovering your mouse over the file and seeing that it tells you that there are only a few bytes on it, usually 44. But what I find is that even a CD burned on Windows Media Player (which will also have all this .cda extension) will not play on an old CD machine or car CD player if it contains MP3 tracks. I can`t prove my theory at the moment by changing the format from mp3 to wma because my dear ( Actually, it`s not correct, a file .wav is not compressed and can be similar in size to CD audio format, but simply burning a file .wav would not work on all CD players. Some might do this if they are specifically designed to play .wav files.
The format is a CD music format which, as Leo said, is a continuous audio stream on the CD. It`s not true. As mentioned in the article, older audio-only CDs do not have files. They decompressed the raw audio. There is no “file format” that you can save as it creates such a hard drive – you have to run special software to do it. I think it would be helpful if you could update your answer to this question with more information: 3. What formats can be cross-converted, what burning speed can be used, what type of hard drive can you burn to (CD-R, CD-RW, DVD+-R, DVD+-R-DL, DVD-RW, etc.), and whether or not you can burn your files to audio CD data so that they can also be played on older CD players, your audio file conversion and burning software will determine the features available with your disc burner hardware ( i.e. what speeds it can burn or read and what types of hard drive media it can read/write). The hardware, software, and hard drive media must be compatible before you can burn a CD that can be played on any CD drive. MP3 is a compressed format, like almost all other popular audio formats available for Internet downloads and computer use. It uses compression technology to make the file much smaller. A second of silence, for example, will require less data than a second of complex sounds.
When you play an MP3 file, the software you are using decompresses the sound during playback. The problem is that your car stereo probably has no idea about compression or decompression. With the advent and popularity of internet distribution of files in lossy audio formats such as MP3, CD sales began to decline in the 2000s. For example, CD sales from major labels fell by 20% overall between 2000 and 2008, despite overall growth in music sales and an abnormal year of increase,[48] although sales of independent and diY music could perform better and CDs could continue to sell strongly, according to figures released on March 30, 2009. [49] In 2012, CDs and DVDs accounted for only 34% of music sales in the United States. [50] Until 2015, only 24% of music in the U.S. was purchased on physical media, 2/3 of which came from CDs; [51] In the same year, however, more than 80% of music in Japan was purchased on CD and other physical formats. [52] In 2018, CD sales in the U.S. amounted to 52 million units, less than 6% of the 2000 peak sales. [46] In the United Kingdom, 32 million units were sold, almost 100 million fewer than in 2008. [53] On a Red Book audio CD, data is processed using the MSF schema, with timecodes expressed in minutes, seconds and another type of image (mm:ss:ff), with an image equal to 1/75 of a second of audio: 588 pairs of left and right samples. .
