28

*
29
+
* RMS_ATTACK Per-chunk IIR coefficient for the RMS estimator rising
30
+
* toward a LOUDER signal. Smaller → faster attack.
31
+
* 0.3 ≈ 2-3 chunks (< 150 ms) to track a loud transient.
32
+
*
33
+
* RMS_RELEASE Per-chunk IIR coefficient for the RMS estimator falling
34
+
* toward a QUIETER signal. Larger → slower release.
35
+
* 0.997 ≈ 330 chunks (≈ 15 s) to fully settle.
36
+
*
37
+
* GAIN_ATTACK How fast the applied gain is REDUCED (loud incoming signal).
38
+
* Fast: prevents clipping when switching to a loud track.
39
+
*
40
+
* GAIN_RELEASE How slowly the applied gain is RAISED (quiet signal).
41
+
* Very slow: prevents the "pumping" artefact during pauses
42
+
* or quiet passages between tracks.
43
+
*
44
+
* MAX_GAIN Hard upper bound on the boost, +12 dB.
45
+
* Prevents amplifying near-silence to noise.
46
+
*
47
+
* MIN_GAIN Hard lower bound, -12 dB.
48
+
* Prevents crushing content that is louder than target.
49

50

51
