Matiq cff28a605c P1.4: full FUN_180529fe0 decomp confirms mask-canon (scale->IIR->blend->combine+weights->warp->dry/wet->FFT-conv); documented remaining live scalars for bit-exact 2026-08-19 23:34:02 +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 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)
- New detector model: floor(level) + bell_curve * boost, calibrated from
  measured data (summary.md level sweep, 7 data points)
- Transcribed twiddle loader (FUN_18014ec20): Cody-Waite 4-level reduction
  with minimax sin/cos polynomial, constants from Frida memory dump
- Added soothe_constants.hpp with extracted polynomial coefficients
- HARNESS parameters updated to match burst500_b1.rpp (depth=0.864)

Results: burst500.wav reduction now -5.8 dB vs Ref -6.8 dB (was -14.4 dB)

Matiq 71870129c2 dsp/: add spectral detector with envelope + peak suppression 
- Detector computes smoothed spectral envelope
- Finds peaks exceeding envelope
- Creates per-bin suppression mask
- Applies mask in frequency domain before ISTFT
- Default params: sharpness=1.0, selectivity=0.5, depth=0.3

Verified: burst500.wav → output RMS reduced from 0.0678 to 0.0476
 2026-08-17 15:49:48 +03:00
Matiq 7dcbcf49b4 dsp/: C++ skeleton with working FFT/WOLA STFT 
- Cooley-Tukey radix-2 FFT (forward + inverse with /N normalization)
- WOLA STFT/ISTFT with Hann window (nfft=2048, hop=512)
- WAV16 read + WAV24 write (fixed aliasing bug in read)
- Fixed in-place processing bug (separate input/output buffers)
- Biquad filter (peak/shelf/reject)
- Peak detector skeleton
- MS encode/decode (M8 stereo)
- Harness: WAV16 → STFT → WAV24 passthrough verified non-zero output

Verified: burst500.wav passthrough produces output RMS=0.0678
