Hi

my goal is to get bit-perfect playback with as few as possible influence on the signal by Mediacenter. Therefor, I am using ASIO-drivers for my firewire-connected RME FireFace AD/DA (capable of 24/192).
I read in the forum, that internally, MC works with 32bit.
I also saw an option in the DSP section "same bitdepth / same sampling rate like the original signal" that you could change to different bitdepths and sampling rates. I left that whole section unchecked to avoid any influence.

- where does that 32bit-processing from MC kick in? Is it used with ASIO-playback from ripped CDs?
- Talking about bitperfect playback with ASIO-drivers: where are (eventually hidden) options, that I need to check/clear to ensure that?
- What are the pro's or con's to use the DSP-option and choose 24bit and/or 88.2 or higher sample rates for ripped CD's - in other words "upsample" the signal?


Thanks!

The internal digital signal processing is used whenever MC alters the signal somehow.

At least these options need to be disabled for bit perfect output: everything in DSP Studio, Internal Volume (maxed out = bit perfect), Cross-fade and Do not play silence (leading and trailing).

I have used 24-bit output when any internal DSP is enabled. At least in theory it gives more headroom than 16-bit.

Changing the sample rate does does not increase the audio quality. An exception is if the soundcard always resamples 44.1 kHz to 48 kHz and uses a mediocre HW upsampling. Then 48 kHz should be used.
