WAV files are divers as lossless, meaning that files are large and consummate; nil has been lost. Professionally recorded CDs are also a lossless audio source. In dissimilarity, the three audio formats listed below are lossy-redundant and not-auditory information is removed to allow for more compact storage; in essence, some information has been lost. This procedure of removing data to shrink the file size is chosen compression. The three file formats below must begin with a lossless format (such every bit a reckoner WAV file) then compress information technology. Nigh lossy formats avowal niggling or no detectable modify in sound quality.

AAC compresses better than mp3, losing less audio quality than its older cousin. The chief drawback is that AAC files have a piddling longer to encode than mp3, so batch sound conversion takes a longer.

Ogg Vorbis (.ogg)

Ogg Vorbis (.ogg) is another compressed source code similar to MP3, but similar WMA, more compressed. Ogg Vorbis is as well open source (gratis to all, unlicensed, no strings attached). While MP3 compresses information at a constant scrap charge per unit, Ogg uses a variable scrap rate. To illustrate-if y'all are copying chunks of silence into MP3 format, the compression chip rate stays the aforementioned as if you were compressing the audio of an entire orchestra. Just if you are copying chunks of silence into Ogg, your compression rate volition drop to nothing. The charge per unit varies with the need.
