- Audio CDs are physical discs that store music in uncompressed format, resulting in high-quality sound. They can be played on CD players, car stereos, and computers with CD drives. On the other hand, MP3s are digital files that use compression algorithms to reduce file size without significant loss in audio quality.

Aug 20, 2006 · Let’s look at the two different formats first. Audio CDs are designed for one purpose: audio. They contain raw, uncompressed data, in a very fixed format: 44,000 samples per second, with each sample consisting of a 16-bit (2-byte) number for each of the right and left channels.

The compact disc first appeared on the music scene in 1982 as a replacement for the vinyl record. CD sales soon surpassed records and eventually cassette tapes as well. It originally was used for audio recordings, and later on was adapted for data. Other types of discs were derived from this original format to store videos, photos, and other digita...
There are three principle types of discs: standard (CD), recordable (CD-R), and rewritable (CD-RW). You can identify the type by printed logos on the disc itself. The same logos usually appear on players or burners as well so you’ll know what works with what. If you don’t see a logo on a device, it’s most likely listed in the manual. There are diff...
Typically used in a computer, a data CD is formatted to store certain files like word documents, spreadsheets, or graphics, and it is often used for transferring or backing up information. A good example of a data CD is one that’s used to install software on your computer. Data CDs are also used for storing personal documents like banking informati...
Audio compact discs are specially formatted with tracks for listening to music, lectures, book readings, etc. An example is a CD of your favorite band that you bought at a music store. Because this type is a universal format, it can usually be played on most CD players. This does not include CD-RWs, though.

Mar 8, 2008 · The primary difference between lossless compression for computer data and for audio is that the latter permits random access within the file. (If you had to wait to unZip the complete 400MB file of a CD's content before you could play it, you would rapidly abandon the whole idea.)
- Lossy audio. This is a compression technique that does not decompress audio files to their original data amount. Lossy methods provide high degrees of digital compression, which results in smaller files.
- Lossless audio. This is a compression technique that decompresses audio files back to their original data amount. Lossless methods can provide high degrees of digital compression, but there is no loss in size or sound quality.
- Uncompressed audio. This is an audio file that has no compression applied to it. The sound in uncompressed audio files remains the same as when it was recorded.
- FLAC (Free Lossless Audio Codec) FLAC delivers CD-quality audio in a file size smaller than an actual CD. It's also a non-proprietary, open-source codec that's great for software developers who want to use lossless audio.

- Compressed vs uncompressed audio files. First, let’s talk about the three categories all audio files can be grouped into – uncompressed, lossless and lossy.
- WAV vs AIFF: uncompressed audio file formats. WAV and AIFF are arguably the most popular uncompressed audio file formats, both based on PCM (Pulse Code Modulation), which is widely recognised as the most straightforward audio storage mechanism in the digital domain.
- ALAC vs FLAC vs WMA Lossless: lossless audio formats. Everyone loves a FLAC. A lossless file, the FLAC (Free Lossless Audio Codec) is compressed to nearly half the size of an uncompressed WAV or AIFF of equivalent sample rate, but there should be no “loss” in terms of how it sounds.
Audio CDs and MP3s are both popular formats for listening to music, but they have some key differences. Audio CDs are physical discs that store music in uncompressed format, resulting in high-quality sound. They can be played on CD players, car stereos, and computers with CD drives.
Jul 23, 2015 · The digital audio stream presented to the DAC originates with a computer. That computer receives the samples either from sound files stored on a hard-disk drive (HDD) connected directly to the computer, or from the local area network (LAN) in your home.
