Hi everyone i am trying some upsampling for improved sound quality and was reading an article in TAS and i am confused. It is from the Absolute Sound's series of articles on computer audio. They address the issue of "pre-upsampling" vs "real-time upsampling" of audio data. It was clear from their report and confirmed by their own listening tests using MC that pre-upsampling 44kHz/16-bit CD quality files, regardless of the original format, resulted in an overall improvement in the sound compared with real-time upsampling.  So my question is how do i set MC to do the pre-upsampling? thanks!!   ?

You can use the free r8brain Sample Rate Converter to pre-upsample your Music and then play it in JRiver, but as a result the pre-upsampled files will take additional space on the drive...

metalman,

What makes you think that upsampling would improve audio quality? Do you have a specific audio quality problem that seems to be cured when you set a higher sample rate?

I don't believe it was ever published online.  More here under "Reviews".

Why are these so similar?  ?

There's no reason to pre-upsample vs real-time upsample.  The only thing that matters is the upsampling algorithm.

Media Center has an audiophile grade upsampler.  It sounds transparent and instrument tests very well.

There's no easy way to explain why upsampling would help sound unless you're overcoming a shortcoming of your DAC.  So I don't recommend it with good hardware, but listen for yourself and pick what you like best.
