View source for User:UED77/Lossless comparison

The '''lossless comparison page''' aims to gather information about lossless codecs available so users can make an informed decision as to what lossless codec to choose for their needs.

== Introduction ==
Given the enormous amount of [[lossless]] audio compressor choices available, it is a very difficult task to choose the one most suited for each person's needs.

Several people only take into consideration compression performance when choosing a codec. But as the following table and article shows, there are several other features worth taking into consideration when making that choice.

For example, users wanting good multiplatform compatibility and robustness (E.G, people sharing live recordings) would favour [[WavPack]] or [[FLAC]]. Another user, looking for the very highest compression available, would go with [[OptimFROG]]. Someone wanting portable support would use [[FLAC]] or [[ALAC]], and so on.

En fin, this is not a matter worth getting too worked up about. If you later find out the codec you chose isn't the best for your needs, you can just transcompress to another format, without risk of losing quality.

'''Note:''' for latest comparison of lossless compression, scroll down to the [[Lossless comparison#External links|Links section of this page]].

<nowiki>*</nowiki> The Compression ratio is calculated with the division of compressed size by uncompressed size * 100. So, lower is better.

Encoding speed, Decoding speed and Compression ratio are based on each encoder's default settings.

<nowiki>**</nowiki> Flexibility refers to the amount of encoding choices offered to the users (Fast/low compression, Slow/high compression and everything inbetween)
