[FR] Real-time volume normalizer.

[boromyr]

It would be a great feature to integrate into the app an automatic volume control, which operates in the background while using Windows and keeps the volume normalized within a certain range. The effect is similar to automatic gain control (AGC) in electronics, which counteracts sudden volume changes by decreasing or increasing it based on previous volume variations.

The process could be summarized as follows:

• Saving the volume value at regular intervals
• Calculating volume changes over time
• Activation criteria: e.g. if the volume changes beyond a ±10% range, decrease the volume by 5%

The effect is further described on the AGC and Dynamic range compression pages.
