1) More than a few readers were interested in what is in my vinyl collection. It isn't huge, but it represents a lot of carefully chosen favorites, always purchased on a strict budget, from the 60s through the 90s. (The quantity of "cut outs" in my collection -- that is, records with a hole punched in the sleeve -- is testament to my budget restrictions.) If you are interested, I will send you an Excel spreadsheet of the collection, derived from Discogs. Just send me a request via e-mail or through the "Contact" button above.
2) Once you've decided on a file type -- MP3 or FLAC -- you'll have some options on the quality level within that file type. These are settings made within the file type's dialogue in VinylStudio. Without going deep into the technical details, the higher the number you choose, the higher fidelity file you will create and the bigger the file size. Either way, MP3 files, even when recorded at very high sampling rates, will virtually always be smaller than FLAC files, even if the FLAC file is recorded at lower sampling rates.
