Hello all,
I'm setting up a hi-end stereo system fed from flacs on a linux based
PC.
I want to be able to experiment with upsampling algorithms on the hard
drive and then feed the digital data stream to a Lavry DA10 at 24/96.
What do you expect to achieve by upsampling before feeding the signal
into the the DAC and amplifier?
The Perpetual Technologies devices (P-1A D/D & P-3A D/A) were very
successful
a few years ago with their hardware based upsampling. I'm hoping to
achieve
something similar by writing upsampling code that can operate in non-real
time
on a PC chip. The idea is that the items 2 or 3 songs down a playlist can
be
upsampled to hard drive whilst waiting to be played. The upsampling
algorithms
can be more convoluted and even multipass if that helps the music.
