When DirectStream sees exactly the correct pattern, it displays a green check mark and the words Bit Perfect near the upper left of DirectStream’s display.

You can download it from the PS Audio web site by going to the software section of our Downloads page. It’s a special flac file that you can play. To check that all of this has been done correctly we provide a bitperfect test. For a good DSD experience turn all of these fading features off. Similarly some players offer fading or other transitions when starting, stopping, seeking, etc. I recommend not using the Direct Sound fading options if you want clean transitions or gapless playback of DSD. During these fadings the output won’t be bitperfect. Direct Sound has the capability of fading the end of an item down, fading the beginning of an item up and/or crossfading two items together. The next things that can “break” bitperfect playing are some settings in the players or the drivers.

I repeat you need to do this no matter which drivers you use: ASIO, WASAPI, Kernel Streaming or Direct Sound. And another OK will close the Sound control panel.

On the Advanced tab the critical items are that both Allow applications to take exclusive control of this device and Give exclusive mode applications priority are both selected. On the enhancements tab click Disable all enhancements. Hit OK to go back to the PS Audio Perfectwave DSD device properties dialog. so there is no display of a little red circle with a line thru it.) Click on Balance and verity that both the left and right are at 100. On the Levels tab you should have the Speakers slider all the way to the right (so 100 is displayed there) and the mute icon set to unmuted (i.e. On the General tab you should have Device usage: Use this device (enable). Now find the PS Audio Perfectwave DSD device and click on it. Select what you want and then click Set Default. In general you’ll probably want some other device than the PS Audio Perfectwave DSD device to be your default playback device. In the sound control panel pick the Playback tab. You can get there thru the start menu, or by right clicking on the little speaker icon in your taskbar tray and selecting Playback devices. Here’s a quick walk thru of what to watch for.

In windows there are multiple places processing can mess things up.

I’ll only describe Windows 7 here because I don’t have any experience with recent Apple products and don’t have Vista or Windows 8 in hand. You need to do the following no matter which drivers you use: ASIO, WASAPI, Kernel Streaming or Direct Sound. But WASAPI or Direct Sound can be used successfully to do bitperfect playing as well.

We prefer using ASIO for the DirectStream because the ASIO driver works and has fewer things to set up. With DirectStream we provide USB drivers from Thesycon which are very good. It’s also often the case that ASIO drivers are more twitchy than those of WASAPI, Kernel Streaming or Direct Sound. This ISN’T TRUE for the drivers which come with the DirectStream. It’s often stated that an advantage of using ASIO drivers is that it bypasses the OS’s volume controls. The more problematic volume controls are potentially in your OS. JRiver on the other hand has an option to pick one of four different volume control implementations – be sure to pick the one that’s best for you circumstances, but some of them can break DoP bitperfect playing. If you are playing DoP foobar2000 and JRiver bypass ReplayGain for DoP so there’s nothing to worry about there.įoobar2000 has one volume control – it’s automatically bypassed for DoP so once again it’s not a problem when playing DoP. ReplayGain may break bitperfect playback but it is quite benign in the sense that when configured correctly it won’t “hurt” your audio EXCEPT if your DAC is only looking at, say, 16 bits. You are more on your own in Foobar2000.īoth JRiver and foobar2000 have support for things like ReplayGain. JRiver MC has a very handy button in the standard views: it looks like a little three slider mixer it shows the audio path which gives a quick summary of what the heck is happening to your audio in JRiver. upsampling)Ĥ) They want to do the least “damage” to their audioĭifferent players have their own quirks and support for bit perfect playing. There are multiple reasons people might want to have bit perfect transmission from their player to their DAC:Ģ) They want to send, DTS to a processor which decodes DTS into multiple channels.ģ) They want to verify that the player or OS isn’t accidentally doing some sort of “evil” processing (e.g. We have a bitperfect test you can perform with your comper and DirectStream Here are the reasons why you might wish to do this:
