|
| |
| int | pair |

| | consecutive frames the band has wanted OUT
|
| |
| uint8_t | smode [16][128] |
| | per-pair previous stereo mode per band, two banks per pair (long/short grid): each grid's memory persists across the other's frames instead of being wiped at window switches
|
| |

| | last decided stereo mode per band index (side-band tests)
|

|
| |
| int64_t | rc_frame_num |
| | frame the reservoir was last advanced for
|
| |
| float | lam_rc |
| | global-lambda rate control: operating lambda, 0 until bootstrapped
|
| |
| int | rc_fill |
| | virtual bit reservoir fill, + = bits saved vs nominal
|
| |
| int | frames_since_short |
| | long-block frames since the last short run (the "gap"): large = isolated transient
|
| |
| int | prev_was_short |
| | previous frame was a short block (for run-start detection)
|
| |
| float | run_burst |
| | transient bit-burst factor, set at run start and held across the short run

| float | lam_slew |
| | final operating lambda of the previous RC frame (slew-limiter state)

|
| |
| float | press |
| | rate-pressure ramp [0,1]: lambda EMA against anchors that scale up when nd_ema flags noise-class content (psy masks unreliable there, lambda reads inflated)

|
| |
| float | lam_long_ema |
| | smoothed operating lambda of long frames
|
| |
| float | lam_floor |
| | lambda min-tracker (snaps down, +2%/frame up): sustained-strain floor; bursty spikes at a comfortable rate cannot raise it
