Re: [Musicpd-dev-team] Best Sinc Interpolator
Upsampling works, but only multiples of the native source - ie 44.1 to 96 the computer is not powerful enough. however 44.1 to 88.2 or 176.4 works also. Don't even try Secret Rabbit Code upsampling in Foobar, would stall right from the first second with the processor at 100%!! http://www.computeraudiophile.com/content/24192-USB-20-beer-budget-EMU-0404-mini-review?page=1 This was written about Windows of course, but it describes my same problem. 44.1-96 is too much for the CPU. Are you sure this isn't normal? That *might* be true for MPD, too, but we don't know currently. My point was: even if libsamplerate eats all your CPU, then switching between OSS and ALSA shouldn't make any difference. I'm curious what's the real cause of this. OK, I'll try to get that report together. Why are you resampling to 96 kHz anyway? My DAC sounds much better with libsamplerate upsampling than sending 16/44.1 to it. Upsampling to 88.1 is a lot easier on the CPU, but it doesn't sound quite as good. - Grant -- OpenSolaris 2009.06 is a cutting edge operating system for enterprises looking to deploy the next generation of Solaris that includes the latest innovations from Sun and the OpenSource community.

No, every resampling process reduces the (theoretical) quality of the file. Now if a 44.1 file upsampled to 96 sounds better than native 44.1 playback, then that must be a hardware quirk. Maybe the sound chip has a fixed sample rate, and plugs a poor hardware resampler in front of it.
