Apple lossless -vs-24/96

Some upsamplers such as Wave Editor on Mac do a good job of upsampling. This can improve the playback sound quality of a 44.1 track on most DACs. Why? Because the digital filter in the DAC has less impact on the music data at 96 than at 44.1. The filter "knee" is much lower in frequency for 44.1 files.

If your DAC has selectable digital filters than you can get around this nad make 44.1 sound really good. This is what my DAC has.

Ok so I downloaded j river 18 and some Hd tracks in 24/96 but my 151 is sill reading at 44.1khz sampling rate. What am I missing? I assume I may need to make sure my sound card is a 24/96 or 24/192 card.

In J River, you need to use WASAPI, WASAPI - Event, or Kernel Streaming. Set that in Tools - Options -Audio - Audio Output. If you are using Direct Sound you get the Windows audio, which is usually does not do 24/96. Also check under Audio - DSP & Output Modes to be sure you are passing 24/96 with no change.

I also use this little tool to see how much content there is in a track above 20KHz. You can also use Audacity or other tools for a more precise look at the file. It is surprising how many HDTracks 24/96 tracks have very little content above 20KHz.

Lads - I believe the Wadia 151 supports 24/96 via USB. That can bypass any sound card you have.

Thanks a lot for the info. I thought I was probably missing something from J River. I will try that and let you know!
