Hi,

What I'm looking for is upsampling perhaps also including DSD which I know JRiver can do but can I play Amazon music HD / hires via JRiver somehow. I was kind of expecting JRiver to install a 2nd sound device that would take audio from any source and apply upsampling / DSP. In other words will JRiver only apply audio processing to sound played from the media center - aka Amazon HD music is not supported ?

thanks for any help

Awesome Donkey:
Audio from different apps can be piped through Media Center using the WDM driver. Not sure how well that'd do encoding everything to DSD though.

I just set Amazon Music Unlimited to play through the WDM driver and add EQ and upsample to 768kHz and it works fine. Only problem is the Windows mixer will be upsampling the 48kHz original to 192kHz before it gets near the WDM driver and MC DSP then upsamples it again from 192kHz to 768kHz. I didn't try re-encoding to DSD as that would have meant no EQ.

It shouldn't be doing that.

It shouldn't be happening and wouldn't be if Amazon had treated Exclusive mode properly but sadly they didn't. All exclusive mode does with Amazon Music is stop any other process from using the device, it doesn't switch bit depth or sample rate to match the original material, instead it re-samples to match whatever the bit depth and sample rate is in the Windows audio settings. My DAC displays the sample rate to confirm. Users have been complaining about this for years but Amazon's developers just ignore everybody.
