Just to make some tests I looped RME ADI-8 Pro input and output, connected
to a RME HDSP9652 (set as master), and I made some measurements:
http://michelespinolo.altervista.org/rme/meas-chain.pdf
this is the looped set-up with hdspmixer (i.e. total mix) at default volume.
Here the same is done:
http://michelespinolo.altervista.org/rme/meas-chain-gain.pdf
but some gain is given on input channel (no analog or digital clipping
occured).
The results in the latter case are a lot worse than first one, but I do not
know why.
My set-up use a Athlon XP 2500+ (Barton core) Asus A7N8X-X motherboard,
Fedora Core 3 (PlanetCCRMA distro), ALSA 1.0.9a.
Anyone has some idea why this occurs?
Thank you very much!
Michele
