Hi,
I am seeing volume control potentiometers on ali express with few resistors and capacitors, for equalizing loudness for different frequencies at lower volumes. How does these work, does these boost low and attenuate highs more at lower volume levels, are any fixed values of resistors and capacitors used to achieve this. I suppose this works with stepper potentiometer or also with stepless?

Loudness controls were popular many years ago and typically use a pot with an extra tapping taken from part way along the resistive track.
The Alps pot as shown on the circuitboard looks like a normal log pot to me (meaning: it has three terminals).
As far as I know, two capacitors and one resistor will not change a normal log pot into an 'equal loudness volume control' as is being claimed.
