plus one on dbpoweramp. The converter can retain the metadata if your WAV files have metadata (artist, album, track number and name, etc.). Even if your WAV files do not have metadata tags, if your WAV files themselves are named (e.g., with track number and track name, i.e., 01 - Come Together, and maybe in directories related to the album, i.e., /The Beatles/Abbey Road), then you can use dbpoweramp or mp3tag to take the file name/location and automatically convert this info into metadata tags.

Love it and not sure I have come across that before.
Clearly I was only talking about myself, if anyone else recognises themselves I was not casting aspersions 
Hi @Echolane , I have had no complaints from anyone else using this feature for quite some time but please if it is not working for you simply run Status Report on your music collection then run Create Support Files and just give me a couple of examples of how it doesnt seem to have worked as expect and I will get right back to you.

Quick note on this, they preserve the metadata if it is one of a standard set of field names, if have metadata stored as a custom TXXX field (that is used for many things) then the field will be converted but it may not be accessible as before. For example when using a MusicBrainz tagger and the ID3 format (as used by Wav, (mp3 etc) the MusicBrainz Release id is stored in a TXXX field called MusicBrainz Album Id, however if tagging a flac file (that uses VorbisiComments) the MusicBrainz release Id is stored as MUSICBRAINZ_ALBUMID
See Appendix B: Tag Mapping — MusicBrainz Picard v2.11 documentation
Now, if you are converting a Wav file to Flac using dbPoweramp it will convert the TXXX:MusicBrainz Album Id to a flac field called MUSICBRAINZ ALBUM ID. But any MusicBrainz enabled tagger/player when using flac files will be looking for a field called MUSICBRAINZ_ALBUMID, so the field is essentially invisible to it.

Very confused as to why some people would set FLAC to zero compression…it’s all lossless. All you are doing is taking up more storage size for no reason.
There also seems to be a bit of “romanticism” being applied…these are just computer files. It doesn’t matter that it’s audio, it’s just 1s and 0s and transcoding from one lossless package to another doesn’t impact those data at all.
FLAC is by far the best packaging format to use and older formats can be batch transcoded to FLAC via dBPowerAmp as some other users have already pointed out. There is simply zero good reason to perform new rips of material into any other format.

Some people do it because computers were considered noisy and that the once heavy processing impacted on the output generated and this may have once been true when they were in under powered 20 years ago.
I will say all my FLAC files are generated at dbPoweramp default of 5.

Mine use maximum compression. They’re still a breeze to decode.

The 209 gb total increase it gave me reripping my CD collection to uncompressed FLAC was a no brainer for me. Storage is dirt cheap nowadays.
A waste is a waste, whether one can afford it or not.
waste
verb
1.
use or expend carelessly, extravagantly, or to no purpose.
You are also wasting energy by compressing at max level which doesn’t make it significantly smaller

I was arguing against uncompressed FLAC, but yes, I guess there’s a balance somewhere. I’ll get back to you on that.
Uncompressed FLAC makes no sense, I just found it mildly funny to be offended by this waste, which may well be insignificant for someone if their HD is big enough, while creating other waste.
It’s a no brainer to take up 30-50% more space with zero benefit? You do you.
Not offended, just confounded.

I know you’re just a user like me, but if we’re talking about …

I wasn’t the one who first made remarks about other people’s waste

Unless using a Mac and making use of Apple products like AppleMusic or an Ipod because they do not support Flac format.
