Sorry to ask but, but why would you want to do that, adding white noise?

I have 2 questions,
- couldn't you use foobar dither instead? (well I know it can only be used at 16 bit output) - What kind of DAC's would not like (digital) silence? -------------------- In theory, there is no difference between theory and practice.

See this topic, maybe.

Yes, Yirkha pointed to the thread where you can see some grounds for this plugin. And, there was an earlier thread with the same problem. QUOTE (Audionerd @ May 24 2009, 15:09) One possible explanation is that only foobar output is truly all zeros when the signal is silent, but I have no way of proving that right now. Suggestions on how to test this are welcome. Well, this plugin can help to prove or disprove it. |

This is genius and a great solution for hdmi audio "silent stream" problem. Could you, by any chance
develop this plugin for other players, for instance KMPlayer? |

In this plugin one can choose to which bit to add the noise. Should the desired output bit depth influence this decision? If I wanted to mimic TPDF noise what would I choose?

QUOTE It depends on what you want. Thank you lvqcl. I was asking what is considered standard or common setting in other software that allow TPDF dither. Would they add the same level of noise to 16 bit and 24 bit target bitdepths? What noise level would be considered normal or common? |

I opened a separate thread to understand the dither and noise terminology a little better.
Now , may I ask , if I wanted to dither to 16 bit output format , using your plugin , would the usual way be to set the noise to the 16th bit? Similarly if the target format is 24 bit should the noise in your plugin be set to the 24th bit? |
