Hi,
My sound card is a 16bit/48mhz, so theoretically enabling dithering and resample should improve sound, or am I mistaken? If not, which resampler should use? The two I have are SSRC and PPHS. PPHS in standard mode isn’t using much CPU, but in Ultra mode it increases my overall use to 15%. SSRC is using the same 15% in it’s highest quality mode. So I would prefer to use PPHS in standard mode, but will I then gain anything at all sonically?

I did not do a listening test about this. I trust people at HA.
Some people at HA say the sb audigy cards (I have an audigy 2 zs notebook soundcard) do a rather bad job on resampling, thats why I chose the pphs resampler to do the job. It's consuming very few cpu. As the resampler preferences page says (may have been in 0.83), ultra mode is not recommended unless you upsample from a very low sampling rate. For 44.1->48khZ, the pphs is fine.

* Q: What resampler settings should I use?
* A: First, you shouldn’t use resampler at all, unless you can tell the difference between resampling being enabled and disabled; resampler is a resource hog and the differences on normal music are very small and virtually impossible to notice (only certain “test signals” such as udial.wav may sound obviously different, but nothing like that occurs in real music). If you really have to use resampler, resample to 48000Hz 1) and use fastest settings. You don’t “gain quality” by resampling to higher samplerate, it’s just like stretching a picture to display it on a higher-resolution screen. You will be most likely able to “play” 96000Hz samplerates on whatever card you have, but samplerates unsupported by hardware will be downsampled by to e.g. 48000Hz before reaching your soundcard.
