More on the Common Audio Formats

WAV is one of the first audio-formats. It is mainly used to store uncompressed audio tracks (PCM) that are identical to the audio CDs in terms of quality. On average, one minute of WAV formatted sound requires around 10 megabytes of memory. CD discs are usually digitized into WAV format and then can be converted into MP3 with an audio converter.

MP3 (MPEG Layer-3) is the most widespread sound format in the world. MP3, as many other lossy formats, compresses the file size by cutting out the sounds inaudible for a human ear. Currently MP3 is not the best format in terms of a file size to the sound quality, but since it is the most widespread and supported by most devices, many people prefer storing their records in this format.

WMA (Windows Media Audio) is a format owned by Microsoft Corporation. It was initially introduced as the substitute for MP3 with the higher compression characteristics. However, this fact was compromised by some independent tests. In addition, WMA format supports data protection via DRM.

OGG is an open format that supports audio encoding by various codecs. Codec Vorbis is the most commonly used in OGG. The quality of compression can be compared to MP3, but it is less widespread in terms of support by various audio players and devices.

AAC is a patented audio-format that has higher capabilities (number of channels, discretion frequency) as compared to MP3. It generally achieves better sound quality at the same file size. AAC is currently one of the highest quality lossy encoding algorithms. A file encoded with this format can have the following extensions: .aac, .mp4, .m4a, .m4b, .m4p, .m4r.

FLAC is a common lossless format. It does not modify the audio stream, and the sound encoded with this format is identical to the original. It is often used to playback the sound on high-end audio systems. Its playback support on devices and players is limited, therefore, if desired, it is often converted to other formats prior to listening in a player.
