FLAC Gets First Update In 6 Years

An anonymous reader writes "The Free Lossless Audio Codec, FLAC, loved by audiophiles for its lossless fidelity has been updated to version 1.3.0. FLAC is an audio format similar to MP3, but 'lossless', meaning that audio compressed in FLAC doesn't suffer any loss in quality. FLAC v1.3.0 is the first update in almost 6 years and it is also the first release from the new Xiph.Org maintainer team." Big new feature: ReplayGain works for sampling rates up to 192kHz so you can finally control the volume of your obsessively ripped LPs.

For fractal it is when you can not find an approximate formula, for Huffman it is when you can not represent a tree + data in less than what you had before, same with arithmetic coding.

      There is an 'upper' limit on most compression out there. But many of the more common ones use byte level boundary to find redundancy. Why is that important? It limits what you can find in duplication. Why do they do that? It is simple, arbitrary bit runs are wildly expensive compared to byte comparisons. Flac made that trade off early on because they have another constraint they have to deal with. Time. They *must* be able to decode 1 frame within a period of time or risk stutter.

    While this is mostly accurate, articles like this fail to mention where 192KHz is useful. That is, for certain types of digital post-processing and effects. Doing a digital time or frequency shift (not a re-sample, that's simple and effectively lossless) yields atrociously poor results if using 44.1 or even 48 KHz. With 192KHz, you can't hear the difference, and that is why it is used in the studio. Auto-tune is a decent example of that kind of processing. It works much better at higher bit rates.

    None of this matters to the average listener though, or to the DJ who only cares about a simple speed up or slow down (or re-sample).

    Wrong. Article mentions it as being useful for processing. Article uses oversampling for antialiasing / cutoff as an example.
    At no point would the signal have to be stored in a high sampling rate to get this benefit. Article mentions most ADCs/DACs handle this shit transparently.
