Yes I do mean about encoding 16bit PCM to 8bit DPCM, but I thought that it would decode losslessly to 8 bit PCM (that delta is only used for convenience, like L/R vs M/S coding). Now I understand that deltas are 8 bit and we need more than 8 PCM bits to decode it losslessly.
So, to summarize - are there any other interesting ways to requantize 16 PCM bits to 8 PCM bits except simply discarding bits, rounding, or dithering with noise shaping? There's so many resampling algorithms...

Not really. And there's no point to encoding 8 bit PCM to 8 bit DPCM, except to possibly make certain waveforms more compressible with conventional compression algorithms on top of the DPCM transformation.
The site you mentioned above encodes 16 bit PCM to 8 bit DPCM, but the deltas still decode to 16 bit samples.
Last post by regor - v2.0.2 - Symlink zip decompressing hotfix This is just a copy of the previous release with replaced symlinks, using duplicated files instead. Some file archivers (like 7zip) don't manage symlinks well and gave errors decompressing the zip... so this fixes it. PeaZip works fine, but since 7zip is pretty popular...
There are no other changes, so if you had no problems using the previous release, can be skipped ## [2.0.2] - 2021-06-20 ### Added ### Changed - Duplicates of main buttons files are now on the root, instead of using symlinks. Some file archivers, like 7zip, did not decompress correctly the releases... ### Removed ### Fixed

I've got a question. Everything was working great, but then I selected the option to not show the playlist on startup and started having problems when I stopped. Sometimes it would crash in georgia-main, sometimes in panel_playist and sometimes it would just show a blank panel. If I displayed the playlist first before stopping, then it worked fine. I'm not necessarily asking for a fix because I can certainly live with displaying the playlist on startup and then just clicking on Details. I just thought I'd let you know. I wouldn't be surprised if I was the only one to try selecting that option. Thank you for this great theme.

DPCM, and also ADPCM, compress the file to delta values, usually of lower precision than the actual sample size. The decoded output would actually be 16 bits, but the compressed file is either 8 or even 4 bits per sample. Information is sometimes lost in the compression process, due to precision limits or other errors, but it usually only differs on the level of mostly inaudible noise.

I recently stumbled upon a bug in the Album List's filter. Capital letters on words seem to make the search case-sensitive. Here's what happened. I searched for
Southern Culture On The Skids
It returned all three albums I have by SCOTS, but for the album "The Electric Pinecones" it only returned one song, "Waiting On You." When I replaced the search with
southern culture on the skids
I got all three albums and all 12 songs from "The Electric Pinecones." The difference is that for two of the albums I used "Southern Culture On The Skids" for the artist name and for "The Electric Pinecones" I used "Southern Culture on the Skids" (blame freedb and laziness on my part for not being consistent).
At first I thought that this might be limited to only capital O's, but I've since determined it is any capital letter. I determined this by creating two dummy files
My only regret.mp3 My Only Regret (take 2).mp3
Searching for "my only regret" returns both files. Searching for "my Only regret" or "my only Regret" only returns the latter file (all searches without quotation marks).
If the search is truly case-insensitive, all of these searches should be equivalent.
