Because FLAC is so fast it can be done at the same time when ripping. But yeah whatever. Doesn't matter.

This has nothing to do with audio - lossless compression has been in use on the computer in the ZIP container format for over 15 years! If there were any errors with the ZIP algorithm, they would've been discovered by now! The following-generation lossless compression formats like RAR and GZIP are merely different lossless compression algorithms that achieve a better compression ratio. All of the original data is still there, you would get an error on the contained file(s) if it wasn't. Lossless compression is absolutely lossless and there should be NO question about it, and anyone dubious enough to question it needs merely to learn why. Lossless compression may be a new thing for audio specifically but it's been around practically since the computer was invented. The people who doubt this - do you download freeware? Shareware? Online games? Utility programs? More often than not, the installers for these programs are distributed in the EXE format which is also a lossless compressed format. EXEs are decompressed dynamically from the EXE container in the system RAM. Just because this process is invisible doesn't mean it doesn't happen. There is absolutely ZERO difference between a lossless-compressed file and the original uncompressed file as far as the container is concerned. |

Complex stuff like Death Metal or Power Electronics often can only be squeezed by 30% or less, while non complex music like classical symphonies often reach a compression ratio of 60 - 70%. Another reason to use ALAC, FLAC or WavPack is that they can store the tags like MP3 can with ID3 Tags, while WAV has no tagging standard. |
