What is the CDA file?

Compact audio disk or CDA file contains a small piece of data that serves as an index for traces on audio CDs. Each CDA file takes the form of traces xxxx.da and includes the location of the beginning and end of the named track, but not a real sound current. Some torn programs, however, assign a .CDA extension to track when they are torn (copied) to the computer. PCM captures analog waveforms using uncompressed , techniques of digital sampling, which results in a very "real" digital representation of the original analog wave. The song torn to the computer as a CDA audio file is actually a PCM file assigned .cDA.

Although the CDA file containing pcm current is extremely high quality, it also occupies a lot of space and will not be recognized mostly portable digital players designed for use with compressed files. Once it is on the computer, it is easy to convert a pissor cm or a CDA to a compressed format. Some tearing softwareE allows the user to select the format before tearing, eliminating the need to convert files afterwards. Many people, however, like to archive music in an uncompressed state, then make these high quality originals compressed files.

There are two classes of compressed files: lossless and lossy. The first category includes formats that compress files without losing quality. These files are still quite large and many portable sound players do not support them. The lossless compressed formats include FLAC, Monkey's audio sound (APE), Apple® lossless, Windows® media sound sound without loss (WMA) and more.

loss formats sacrifice a little quality for a much smaller track. Unlike the torn CDA file, which carries a full PCM wave current, the loss leaves some data to achieve its much smaller file size. Formats include a well -known MP3, Vorbis, AAC, AAC,WMA (Lossy Version) and others. Quality loss is not very evident in portable devices that rely on headphone output or small portable speakers. In addition to audiophiles, many people cannot recognize the difference between the loss set and its counterpart PCM or the torn CDA file when playing on a portable device.

The advantage of using compressed files on portable devices is that many other songs can fit into limited memory. However, uncompressed files are still recommended for combustion of CDs or audio DVDs for automotive stereos, home stereo and spatial sound systems.
