Empirical Freeway will do this, but the player may need to have settings changed depending on what player you are using. 48kHz is usually 24-bit, so if you are using Foobar, the preferences must be set to 24-bit and then back to 16-bit for 44.1kHz.

Thanks for the quick response.I hadn't really considered sample width - just assumed that any converter that could handle a specific sample width would do so for all frequencies - in fact, from my days in instrumentation, I'd assumed that due to DAC & ADC latency, maximum sample width would if anything decrease as rate increased (and vice versa).
Is this a feature of Asio4All? Does the Freeway have a real Asio driver?
I currently use Foobar (9) set permanently at 32 bit, though as I never do anything beyond 48K I have been tempted to just use 16 bit.
Don't ignore bit depth. This has a major influence on sound quality.ASIO4All does not sound good to me in comparison with proper ASIO drivers. Try to use native card ASIO and experiment with different versions inn Foobar.
"Is this a feature of Asio4All? Does the Freeway have a real Asio driver?"Sample rate is independent of the driver and ASIO. The Driver usually only sets the sample rate or sample rate range.
Freeway and Off-Ramp have a real ASIO driver. You can use several different ASIO plug-ins, and they have different sounds. I think I have about 20 of them for the old Foobar and 5-6 for the new Foobar.
If the purpose for using an asio i/f is to avoid corruption of the data stream by other modules, how can different versions have different sounds?I'm looking for an interface to provide bit-perfect conversion from sound file - or more pedantically pcm data output from a player (Winamp 2 or Foobar 8/9) - to spdif. Surely not rocket science.
This is what I query about computer audio. Some buffs here say bits are bits but those in hifi know that this is nopt so; it is how the bits are transmitted and handles at the interfaces that also matter a lot.Unfortunately there is no clarity (in this world of info freedom and transparency) in computer audio, with some outrageous claims about this & that and usb at 44.1/16 sounding best. There is complete failure to take into account such things as dynamic range, s/n and all the electronics to go with it.
Good question, I wish I knew why but they do sound different.
Any thoughts on the latest ASIO plug-ins for Foobar 0.9 vs. your favorites for 0.8? As I've said, I've compared the latest ones for 0.9 and am no longer hearing a difference with the best for 0.8 (although admittedly the original ones for 0.9 seemed to have some problems).
I'm so buried in orders that I have not had much chance to experiment. I would like to compare the latest ASIO for Foobar 0.9. Which one do you like?
I'm just using the latest one off this page...and I see it has changed again since I last updated. Somebody is busy doing something with it...
