I wrote FAQs section in Fidelizer Upgrade Program page for a while but it doesn’t seem to have good visibility there so I moved out to a new page for easier access from Support menu.

I also added new question about bit-perfect hoping it’ll clear the misunderstanding about bit-perfect making perfect digital audio transport as below.

My foobar2000 has bit-perfect output. How can bit-perfect audio get anymore perfect?

Originally, the concept of “bit-perfect” is about bypassing “OS mixer” to send data to audio device directly. Bit isn’t perfect before because OS mixer will resample all incoming audio data to the same frequency from different applications.

All digital audio problems can’t be solved by simply bypassing OS mixer. Fidelizer puts great effort to reduce software implementation issues in digital audio and we recommend to use Fidelizer with bit-perfect audio applications.
