MC9 Volume Control (does it affect resolution?)
« on: April 14, 2004, 08:33:28 am »

I use JRiver on XP with a Lynx22 analogue out and ASIO direct into an amp. I set all of the gain settings for the Lynx at max to ensure that all of the bits are being used and use the volume fader in MC9. I assume that MC9 chops off the bits to control the volume but I'm unsure. How does Media Center 9 control volume?

Thanks in advance.

The only way to digitally reduce volume is to "chop off bits."  In real world listening, it's not as scary as it sounds.  With most CDs, the 2 or 3 lowest bits of the 16 bits are random noise anyway.

With MC:

In "System Volume" mode, the reduction will be done at the system / driver level.

In "Internal Volume" mode, all changes are done in our 32-bit player core.  This is ideal since it happens after DSP, fades, etc. while the data is still in 32-bit format for maximum resolution. (requires MC 9.1 or MC 10.0)

Thanks.
