Did you mean "can't" rather than "can"? I've never found a way to add metadata to WAV, although in the past when I used to use iTunes you could certainly create metatdata and attach it, but that was iTunes own internal database and not actually part of the WAV file itself.My opinion on this is has always been that if you can hear a difference between lossless compression and uncompressed files, your streamer is to blame, not the codec.
Also, you can add metadata to .wav files.
Hi,Does the server decompress the Flac file and send the data as a pcm stream or does it send the flac file as it is and player then decompresses the file and plays it ?
https://xiph.org/flac/documentation.htmlI have been looking for some articles on this subject and can’t find a single one. Not even Wiki FLAC page has info. Seems crazy that there is no documented info on how and where FLAC is unpacked and if and how it might cause audio problems.
Is the metadata stored within the wav file (handy if one changes to different software or hardware) or in an associated database?You can add metadata to WAV. Most modern streamers support it.
Thanks but there doesn’t seem to be any info on this specific topic. Maybe you could point to exactly where it is?

Thanks, interesting range of software. I’m a bit confused as in their faqs they state:I've been ripping to WAV's since the Squeezebox touch first appeared and metadata is usually added directly to the files automatically when ripping with Windows Media Player. Where it has to be done manually or edited later I use "Stamp" from NCH software :

The metadata is recognised by the SBT and a Cambridge Audio Minx XI no problem, using Logitech Media Server.
This document does not mention decoding at all and nor does it mention ANY of the points in your response. (And some streamers send data via USB to a DAC).Hi,
The page :
https://xiph.org/flac/documentation_format_overview.html
Has more information on the encoding process. Decoding is the reverse operation. There are no errors or audio issues. Any implementation either works or it does not.
The DAC IC's are not able to decode FLAC files, nor can the FLAC file data stream be transmitted along the SPDIF to the DAC. As such, all processing of FLAC has to be implemented in the streamer. This process can be in software for OS embedded type streamers, or a specific IC as per the cheaper streamers or media centres (sigma designs processor).

We need to read a technical specification document describing it rather than the opinion of a guy in the internet. But of course if you did write the FLAC technical spec please give us a link to your document.
