None of the machines uses the gain ramp possibility for HS/HF. This code path is mostly unused and it does not reduces the pop noise on the output (it alters it to sound a bit different). The preferred method to reduce pop noise is to use ABE.
...to implement gain changes?
To fix up the pop noise.
After this feature was implemented to reduce the pop noise it become clear that the underlying issue can be better solved with the offset cancellation feature within ABE. It turned out that the ramp code (which was implemented and deployed at the same time as the ABE offset cancellation) alone just alters the quality of the pop. With the ABE solution alone we are fine.
Applied, thanks.
Thank you, Péter
