I find it useful. I think the samples demonstrate quite well:
- the differing results from omnis and cards in the same location
- the benefits of mixing omnis and cards
- the benefits of mixing SBD + AUD
If I was a new taper, or even an experienced taper considering omnis or cards (whichever I didn't already have), I'd find this very useful. I think ultimately a louder, heavier electric band might prove more useful for most folks, but I still think the results are applicable.
I'm adding a few of my comps to tapers.org...
NJB3 v. D100, line-in
SX-M2/LS2 v. NBox
Dither comparison
...and I can host these samples, as well. I don't know that 24-bit is necessary, though I think 16-bit would offer better perspective than MP3. We may also host useful comps directly here on TS, but haven't wrangled the details yet.
