![]() ![]() However, has taught me that you can downsample a 96k source to 44.1k and then resample it back to 96k, and the result will be 100% bit-perfect to the original for frequencies below 22.05kHz. The problem, rather, is the 44.1k vs 48k (and multiples thereof) difference, with redbook being the former and most high-res files being the latter. I use Macs and greatly prefer MacOS to Windows - but MacOS doesn't support on-the-fly sample-rate switching either.įor me the problem isn't upsampling per se - I couldn't care less if my OS turns my 44.1k source material into 88.2k or any other multiple of 44.1k before sending it out to an external DAC - it's just duplicating samples, who cares? PowerDVD supports exclusive mode in similar manner while system mixer is bypassed.įoobar requires a plugin which unfortunately does not read input stream, and has to be configured manually. MediaPlayer Classic Home Cinema switch to 48KHz 24bit instantly for BluRays with DTS-HD MA audio. This mode sends data direclty to the DAC without any interference from OS. For playing media I recommend WASAPI Exclusive mode. Using sample rates multiplied by 2 (88.2 or 96Khz) does not seem to have any positive measurable effect.ģ. ![]() Resampling from 44.1 to 48 and vice versa is causing distortion so try to avoid it. Supposedly this measurement should mean lower distortion.įor my specific configuration its 44.1KHz at 24bit as its maximum output for the both DAC and Optical SPDIF Sinewave at 24bit was still keeping most of its shape, where 16bit sinewave completely turned into noise. I sent 1KHz sinewave and captured it using 44.1KHz at 16 and 24bit through software oscilloscope, and then I started to decrease volume. I considered it to be a snake oil, then i did measurements myself. Since the sound gets mixed higher bit rate may reduce dithering artifacts. Its native for most of the content (games, CDs, streams). Just select 44.1KHz at 16bit and dont think about it. What would be best sample rate (for Shared Mode) For a long time 44KHz or 48KHz 16bit were the only two options, now even with more options there is lack of content.Ģ. Part of it is a mixer (which should now work on 32bit float) which combines all the sound channels and then outputs them to the sound card. As it happens 98% of PC audio content is indeed 44.1KHz 16bit which was back in later 90s accepted as standard not only for CDs. This is an approach since Windows 98SE WDM drivers and its sort of "multitasking" on audio level. Windows allows multiple sound sources to get mixed and overlap PS : the questions are both valid for Win 7 and Win 10, since I have both.ġ. ![]() I hope your answers will finally ease my mind. So I guess I should just set everything to 32bit/44.1 KHz and be done with it, right ? But then what's the point in even having higher sample rate files ?. Me, for example, 98% of my files are 16-bit/44.1 KHz (like most of you I guess). My second question would be : since it seems that we can't do that (adjusting sample rates dynamically), what would be the "arguably best" sample rate in a SCIENTIFIC, measurable way ? (I don't care about listening impressions, only measurements count). So my first question would be : how come that in 2021 nobody has yet found a way to dynamically adjust Windows sample rate to the played audio ? Basically it's telling Windows "don't touch the signal : if it's 16-bit treate it as 16-bit, and if it's 32-bit treate it as 32-bit". So for all of us who have audio files / 48 / 88.2 / 96 / 176.4 / 192 KHz and so on, we have to juggle with Windows sound panel and adjust it on the fly before playing a given file (which quickly becomes unmanageable), OR just set it to a fixed sample rate and leave it. Great !īut sadly, sample rate is another story. It's one thing to set Windows bitrate to the maximum possible : in my case 32-bit since my DACs are 32-bit, so it allows for playing 16-bit or 24-bit music, with even some headroom for digital volume control. ![]() Hi guys, I've been wondering this for a while now, but I've never found a clear answer. ![]()
