![]() #Reclock enable bitperfect audio windowsTo verify what mrmuppet said, The windows Sound Default Format options that he posted a picture of are the only thing that I have found that actually changes the outgoing sample rate. (redundant I know, but I had it handy and it has an SPDIF output I can use as a pass through device)Īnyway, my DAC has a row of lights indicating different sample rates (32khz, 44.1khz, 48khz, 88.2khz, 96khz, and 192khz). I have a dac (Musical Fidelity M1DAC) connected to an SPDIF output from an ASUS XONAR ESSENCE STX. Yes, I use ReClock, however I don't want to use WASAPI Exclusive. If you have a crappy soundcard with a fixed internal sample rate, audio could be resampled twice (first by the Windows Mixer to say 44.1 kHz and then by the shoddy soundcard to say 48 kHz). ![]() #Reclock enable bitperfect audio softwareIt's the Windows Mixer doing the mixing and software resampling (one way or another) in this case. Upscaled bitrate would make no difference for lossless, but actually improve the quality of lossy floating-point sources (like MP3, by virtually eliminating rounding errors without having to add noise to dither). Oh, and it's not bitrate we're talking about here, it's sample rate. I listen using headphones too btw (DT-770). (Differences should be emphasized for very high frequency, the Nyquist rate and all that.) But some people want it "right" regardless, it makes it "feel" better and improves the experience (placebo or not). And you should be listening to lossless sources obviously (if nothing else to avoid the high frequency cut-off). It's not that easy to even differentiate between properly resampling to 32 kHz and using 44.1 kHz bitperfect. You claiming not to hear a difference doesn't say much. I think that's where I got it from actually (either that or HA), although it seems like the intuitive thing too. This can be the SRC as supplied by Win or one supplied by the application." Sample rate conversion must be done by the application sending audio to the mixer. ![]() you play a CD but your sound card only supports 48 kHz (the cheap ones do) you downloaded some 24 bit/176 kHz recordings but your sound card supports 24 bit/96 kHz max. "Any stream not having the default sample rate as set in the Win audio panel, has to be converted before it is send to the mixer.Īnother reason to apply sample rate conversion is a mismatch between the sample rate of the source and the sample rate(s) supported by the hard ware.Į.g. I have never seen or heard anything indicating that audio is not resampling by Windows' mixer when not in "exclusive mode". If your audio collection is mixed, you won’t have automatic sample rate switching with DS."Īnd here too it says that DirectSound is resampled in Vista: In the audio panel you specify sample rate and bit depth.Īll audio not having this sample rate is resampled to match this setting. The default (Direct Sound) sends all audio to the mixer. "With Vista a new audio architecture was introduced. I'm not sure what type of sources you're looking for. ![]()
