To give you an idea. Just a rough calculation but 3hrs would be about 7.75GB in 2.8224MHz/1-bit DSD or roughly 7.5hrs on a 20GB HD.
Record times on 4.7GB DVD+rw media from the Tascam DVRA1000 manual :
109 mins 2.8224MHz/1-bit DSD
How is the math on that? Couldn't work it out..
bits/s times seconds per hour
divided by bits per byte
gives bytes per hour
given the capacity per dvd you can work out the rest.
Ok here we go:
2.8224Mhz = 2,822,400 bits/s = 10,160,640,000 bits/hour = 1,270,080,000 bytes/hour
A dvd is about 4,700,000,000 bytes.. So that's 3.7 hours per DVD?
So I guess the 2.8224MHz is per channel? In that case it's 2,540,160,000 bytes/hour, which gives 1.85 hours per DVD.
That's more like it ;-)
So, on the internal 20GB hard disk, that would fit almost 8 hours. Not bad!
