I can confirm this. I tested with 3.100.1 and the following encodes of hihat.wav: -q0 -b128 (b128) -q0 -b160 (b160) --preset cbr 128 (pc128) --

I can confirm this. I tested with 3.100.1 and the following encodes of hihat.wav: -q0 -b128 (b128) -q0 -b160 (b160) --preset cbr 128 (pc128) --preset cbr 160 (pc160) --preset 128 (pa128) --preset 160 (pa160) Using the Foobar2000 ABX comparator I was able to 5/5 ABX: wav vs. b128 wav vs. b160 b128 vs. b160 (this one was 7/8 ABX) wav vs. pa128 wav vs. pa160 b128 vs. pa128 (more difficult) pa128 vs. pa160 (more difficult) I did not successfully ABX b160 vs. pc160. I didn't do ABC/HR so I can't say for sure what my ranking would be, but my guess is: wav >> b128 > (b160 or pa160) > pa128
