In real systems you do get some variance, and the receiver might be set up to accept a range of 0.7v-1.3v as a '1'. So now imagine that instead of receiving 1.0v to indicate the current data bit should be a '1', the receiver instead receives 0.9v. The receiver of the message uses the table in reverse to reconstruct the message. The message above was formed by taking each character and looking up the special binary value in the ASCII table (very common character encoding scheme). To transfer the message 'hello world' you could send the following bit stream: The receiver will check the voltage on the input at fixed intervals, and record the results (i'm glossing over complexities around timing between sender/receiver here). So if it is an analogue signal, how come it's referred to as digital?Дifferent links encode information differently, and I'm not going to find a data sheet on USB (which would be too confusing for this example anyway), but imagine a simple encoding scheme where you sample the signal, and if you read 1.0v it means '1' and 0.0v it means '0'. This wire is obviously transferring an electrical signal, and of course all electrical signals are analogue by nature. So in this example, we have a USB connection between your computer and the DAC. I am not an expert in digital signal processing, so I'll be glossing over some details, but it should give you a good idea of the principles of whats going on. Search google for 'bit perfect' tests and you will find a lot more info.ДЄlright, I'll try to explain in more detail. If the receiver can decode it as DTS then I believe you are streaming in bit perfect mode. If the data is being messed with by the OS mixer, you'll just hear static or silence. If you are feeding your dac via coax, an easy way to test it is to try feeding the coax signal (that normally goes to the DAC) to a HT receiver. You may just be able to use an application like VLC or foobar with audio at 100% and get bit perfect audio, but without some kind of testing you can't be sure.

If you're using windows, you can try foobar with the ASIO driver plugins. There's a number of ways to bypass the OS mixer the specifics depend on your OS and preferred application. It means that what the data that is in the audio file is sent perfectly to the DAC, in the same way as your example of an excel sheet. This is what people are referring to when they talk about 'bit perfect' audio.

Now obviously your nice DAC is going to do a better job than any software mixers so you want to bypass all of this. Also, the audio is mixed to a common sample rate - almost always 48k. In modern OS's, users are also given the ability to change volume on a per application basis. For example, system sounds from windows explorer when you change folders can occur at the same time as another application is playing audio.

In a typical PC application, users expect multiple device signals to be mixed together. This has nothing to do with whether the signal can be detected by the DAC. The digital audio file that is stored on your computer has (effectively) a volume level embedded in each sample.
