Okay. First question, how loud is the MBIT+ dither?
Quantization noise using standard TPDF dither is 4.7712 dB louder than quantization noise without any dither. (But it’s better noise.)
Is MBIT+ quantization and noise louder yet?
What is the PDF used? Triangular? Gaussian?
Finally, care to divulge what the noise-shaping transfer function is? We can see you’re dumping a lotta energy up there in the top octave just below Nyquist.
