![]() So here is a player which has earned its scratches. When I worked in Nordic Semiconductor we used it to demo the wireless audio solution nRF24Z1. It does that for very long time on a measly pair of AA batteries. The most obvious thing it does it of course to play CDs. I can't help but be amazed at what Sony was able to cram into the little box. It came out when the CD medium was at its peak. I'd like to tell you about an old and trusted companion, my D-NE700 Discman. The built-in Windows WASAPI protocol also drops sample rate conversion.Īny feedback? Please use The Henry Audio Facebook page Software can be JRiver Medial Player or Foobar2000 with an ASIO driver. But in that case you're probably using player software which does not trust the operating system to handle outgoing music. There are special cases when you have downloaded hi-res music where you want to useĪ different sample rate from the original CD specification. This is a screen dump from slide 15 of the AES lecture I gave (see below).ĭo all programs and all music benefit from setting a fixed sample rate? Well, I'd say 99% of them do. I can talk you through it but your best option is to see it on picture.įollow this link and look at the instructions. How is this done? It involves a pretty little dance of left and right clicks. I can fill you in with a lot more math if you wish, but trust me on this: preventing the operating system from resampling your music will in give you a better experience of it! The result is that more thanĩ9% of the original samples in the music are slightly altered in order to be played back at a slightly different rate. Then Windows will resample your 44.1ksps music to such a rate. When a DAC is plugged in, it almost always presents one of the 48/96/192 rates as its highest rate. When the DAT player was introduced, 48ksps was selected so that copying 44.1ksps CD material was going to be hard! 44.1, 88.2 and 176.4ksps derive from the original CD. But there are two fundamentally different families of sample rates. After that the OS will basically take all music as it arrives from the player software and resample When a USB DAC is plugged in, the operating system asks it which sample rates it supports. So regardless of how you receive that music, playing it back Modern music streaming is based on a source which in almost all cases was a CD. Here I show you how to force yourĬomputer to use the original CD sample rate. Hi-res music recordings can go much higher, typically to 96ksps or 192ksps (kilo samples per second). ![]() But that still doesn't mean you should letĪll CDs are recorded at 44100 samples per second. But with today's chips it's a walk in the park. This used to be a very demanding task on the processor. The sample rate describes how often these time intervals occur. Digital music is stored at certain time intervals. This applies to all USB DACs, not justĬonfused? No wonder. Do you want to tune up your DAC for the maximum performance? Then you should have a look at how to set the sample rate of your DAC. ![]()
