1 bit Gaussian noise shaping appears to do a reasonable job.
This result could be EASILY improved upon in a whole host of ways - not least a bit of noise gating, in fact about ten minutes picking some defaults during the conversion creation process could probably cater for the conversion of 99% of files in a near-excellent way.
Which is rare in computing, lol.
: ) Ill attach my squashed audio and I'll up the video somewhere so you can have a play syncing a decently big file. it's a completely Public Domain movie as are the other ones I have been playing with.
The file I have attached has a constant sizzle, the original soundtrack was HORRIFIC quality, which is what attracted me to it (of course). I'll play with tidying it up and post another to show what I mean (of course I already did noise shaping just to make it a bit harder for me to show a real difference, bah)
I might add that I'll be doing this with unix tools and basic filter settings. given access to my studio I could make this shitty recording sound like a dolby master. Just saying.
But that's not the goal here, just getting some decent - thumb in the air - settings / algorithms is a big step forward toward simpler compliance for terrible recordings.
