Matiq 5a4554a9a3 P4-prep: eval_lut_bin uses float logf/expf (matches decomp FUN_180563440 logf/expf, not double std::log/exp) 2026-08-20 09:26:38 +03:00
Matiq 8fad2bbfd9 P3.5: acc_437c0 = data shuffle (re/im repack + zero-fill), not arithmetic; full butterfly = twiddle load + shuffle + mult + combine 2026-08-20 08:48:00 +03:00
Matiq feb44c3802 P3.4: transcribe plugin's own vectorized ln(x) (vlog.cpp, minimax ln(1+x) poly + ln2 range-reduction); correct prior misread — dispatch reaches runtime ln, not FFT; vlog_check ALL OK (rel 2.4e-7) 2026-08-20 07:12:56 +03:00

Matiq fe43509d50 NOTES_CAPTURE: P1.5 live level-tracker A[]/ctx confirmed unreachable (window ptr only in registry, no +0x24==40000 object); scalars static-derived from RPP; 2 missing consts 0x24c4348/44a4 2026-08-20 00:11:45 +03:00
Matiq c5d2b2ad7f P1.5: rtctx.py live-capture pipeline (registry-scan + ctx discovery); confirms live level-tracker A[]/ctx not reachable (window ptr only in registry, no +0x24==40000 object) => scalars are static-only 2026-08-20 00:11:25 +03:00

Matiq 8b8895f68a P1.3: integrate FFT-conv stage (build_fir_from_window step5 memcpy + fir_from_mask + overlap-save conv) with captured WIN_WINDOW; fftconv_check confirms FIR=window[2048:4096]={0.8->1.0} 2026-08-19 23:25:21 +03:00
Matiq 42316efa71 P1.2: confirm f_52d990 memcpy via decomp (FUN_18052d990(lVar22, window+N/2, N/2)); infer N=4096 from freq-axis spacing + window sape; step-5 low-pass near-flat ramp 2026-08-19 23:20:38 +03:00
Matiq 241957bced P1.2: f_52d990 = memmove/memcpy thunk, NOT a multiply; corrected step-3/5 FIR window semantics (copy window tail + const fill); xmm9/xmm13 remain 2026-08-19 23:17:31 +03:00
Matiq fd9b1fd001 P1.1: embed runtime-captured DSP tables (WIN_WINDOW, FREQAXIS@48k, WA/WB/WC/WD), dsp_ctx registry mirror, tables_check ALL OK 2026-08-19 22:48:32 +03:00

Matiq 6c3ab92405 docs: full roadmap rewrite (drop stale phase-A recap, milestones table, doc index) + README doc links 2026-08-19 17:39:48 +03:00
Matiq 59619e4648 docs: roadmap B.12-B.15 journal + README rewrite (framed_render canonical, honest metric) 
- roadmap: current status header (decomp closed, frame-render model, honest metric),
  new assets (fraed_render/render_parity/handoff/nls_dasm/rwin tables), journal
  B.12 (bridge), Phase5 (dB parity 0.268), B.13 (res_power+decomp LUT/IIR),
  B.14 (Q-dep rp + metric artifact correction), B.15 (joint free-knot LUT, dual mean 0.027).
- README: rewrite to framed_render.py as canonical model; 3-line model formula;
  structure + corpus tables updated; honest-metric warning; next steps focused.
 2026-08-19 17:09:21 +03:00
Matiq 28cd3b7c62 Q-dep rp + honest TRIMMED metric: mean=0.175 (was misleading 0.144 artifact) 
- Exposed artifact: earlier fits measured tone_cmp on untracked-length output
  (nfr*HOP+N); framed_render.synthe trims to len(x). Honest scalar-rp=0.0169
  baseline is 0.280, not 0.160 as previously recorded.
- New model: rp(Q)=rp0*Q^drp, G/W/A/rp0/drp=0.9963/0.3335/0.9807/0.0275/0.2159.
  Trimmed errs: q0.1 0.000/0.001, q1 -0.256/-0.707, q10 +0.086/+0.001.
  q0.1+q10 perfect; bottleneck q1@2000 (structural warp mismatch).

Matiq 847725f5fc dsp/: fix FFT inverse, WOLA normalization, detector model, twiddle loader 
- Fixed execute_inverse: removed conj bug, now uses positive twiddle only
- Added WOLA normalization factor (wola_sum/hop_ for Hann+hop=N/4)

  with minimax sin/cos polynomial, constants from Frida memory dump
