Float16 why ?
What is the interest to do a lossy flac ?
The goal of flac is compress and stay lossless.

AAC/MP3/Ogg are lossy ... why want one other lossy format ? If you listen lossy, you don't look for extreme quality anyway, it's more for practical reason.

What are you talking about?

I am only guessing he is talking about lossy wav compressed as flac.

The goal of lossless codecs is to store data losslessly, no matter if the data is lossy or not. As a counter-exemple, all lossless video codecs are meant to store lossy data, mainly recording mpeg TV streams before re-encoding.

The thing that you don't understand is that what you call "lossless" is in fact lossy: all CD follow the CD standard & there are higher audio recording quality than CD.
So all CD are "lossy" compared to these higher recording possibilities of the same audio data.

You'd better think as "master" or "original" & flac is made to store data, not necessarily "masters".

Seems that you don't understand lossy too ... you don't encode in lossy to willingfully listen to compression artefacts but in order to save space. So the holy grail of lossy is reaching audio transparency. Codecs like lossywav are much more resilient to killer samples than traditionnal lossy codecs, but is it worth it to double the bitrate for so few samples ? Only you can answer this question for yourself. So lossy audio data compressed with lossless codecs increase your choice & liberty.

Once you'll understand the limits of AAC/MP3/Ogg, you'll appreciate hybrid codecs better. Like it or not, they fill an audiophile niche market because their artefacts are fewer & softer if you're ready to pay the HDD space price.

Float16 and lossyFLAC are not equivalent. In any case, this’ll fit better in Other Lossy Codecs with the rest of the threads about either.

In said previous threads, as well as on the Knowledgebase, there is a good deal of information about these processors and their rationales.

True. LossyWAV will happily keep all 24-bits of a 24-bit file perfectly intact if it thinks this is necessary.

It'll keep 10 bits or less if it thinks this is acceptable.
