@Lemberg, Sorry that the audio compression is lower than you prefer. I find 96 kbps to be adequate for my purposes. From my perspective the quality was so low to begin with (pops and cracks and 1930's sound editing) that I might as well have dropped it down to 64kbps.
Ultimately, I made this torrent for the sole purpose of compressing this data, heavily. You have the option of collecting the Hexen DVD ISOs if quality is a primary concern for you. They're all available online, and I've tried to collect them in another of my torrents to make them easy for collectors who demand high quality.
Personally, I'm not an audiophile or videophile. If it's reasonably clear and sounds reasonably good on an Analog TV (no static, not too blocky), my desire to collect old TV shows and old movies is satisfied. I have 3.8 Terabytes of TV shows, movies, and music. A 10% increase in file size means a 10% decrease in the number of files I can store. In fact, anything that I download, which violates my space constraints is summarily recompressed. 400 MB for a 1-hour show, 200MB for a 30-minute show, and 800MB for a movie. Beyond the baseline quality that these constraints guarantee, my primary concern is with the efficient (quantitative) use of my storage resources.
