Oke, I'll try to forget the DiskStream class. The only reason why I am
suggesting it again is the performance of disk I/O.
I saw it while working on Peak.cc
All information was read and write in small blocks. Reading a peakfile was
also done in the same small blocks (sizeof(short))
Reading in a peakfile of ~10 MB was taking about ehm, 2 - 3 second's?! (=
~4 MB/s with continues hard disk acces)
I have a relatively new hard disk which is capable of reading at a speed
of at least 30 - 35 MB per second.
Reading the peakfile at one's, well just look at the output of protux --d1
Of you can read the message: loading peakfile - done, then you probably
have a real slow hard disk. :P
If you want to record with 16 armed tracks, 14 bit 96 kHz (oke, oke just a
worse case scenario) make's: 5.6 MB/s....
Oh well, just forget about it, I'm tired and just are typing nonsense. ;-)
Again, have a nice weekend
