Thank you very much. Bought both.
Perfect license for this kind of assets. And thank you for adding it to the metadata.
To answer your other question:
If you would offer other formats I would not use them.
I organize my bought/licensed assets in the following way:
I only download the highest quality version available (24 bit WAV in your case). After extracting the archive I losslessly reencode every WAV file to WavPack. This makes it small without losing any information and also allow to losslessly compress 32bit float encoded WAV files without having another format involved.
My sound/music asset pipeline is just a bunch of shell scripts that automatically reencode all required audio files to the final required lossy format for that build.
Some artists only offer lossy formats. I add them to the collection without any modification/reencoding.
And some artists have big/"bloated" archives which contain 3 formats. WAV, MP3 and Ogg. I delete all formats except the WAV files and continue as described above.
