LinearPCM/1.4Mbps (more than cd/wav sample rate) and at this you get 1 hrs. 34 min on the 1gb disc.
i doubt that will be crap quality.
ive used the normal minidiscs on lp for yrs and it sounds totally fine...
but the new ones on HD-Standard will be better im sure.
i may try it through a scope at work at different sample rates and compare it with a wav.....but my ears dont notice the diff.......thats all that matters really tho.
