Media

Brighten dull vocals or masters with a high air shelf plus an exciter that synthesizes new top-end harmonics — the Aphex Aural Exciter architecture built from FFmpeg.

Media

Run audio through a simulated tape machine: tanh magnetic soft clipping, speed-dependent head bump and HF rolloff, wow & flutter, and tape hiss — with 3.75/7.5/15/30 IPS presets.

Media

Detect and dynamically attenuate harshness in the 2–5 kHz presence band — a dynamic-EQ-style cut that only bites when the band actually plays loud.

Media

Detect and reduce 150–500 Hz low-mid buildup — the stacked-fundamentals mud that turns a mix boxy — with a measured, focus-tuned parametric cut.

Compression

Upload a PNG or APNG and audit the whole animation structure: PNG signature and per-chunk CRC32 checks, IHDR bit depth / color type / interlace, acTL placement and declared frame counts, every fcTL (region bounds inside the canvas, normalized delay fractions, dispose_op none/background/previous, blend_op source/over), the shared fcTL+fdAT sequence-number contract from 0, per-frame replay of the IDAT/fdAT deflate streams with exact decompressed-size verification, and disposal-semantics audit — first-frame PREVIOUS treated as BACKGROUND, zero-delay frames, loop counts, fps and compression ratios.

Development

Decompose a directed or undirected graph with Tarjan's 1972 iterative SCC algorithm cross-checked against Kosaraju's two-pass; find articulation points and bridges via low-links; build the condensation DAG with a Kahn topological order; report cycles (nodes on cycles, self-loops) and depth-limited BFS/DFS traversals.

Media

Map world tunings — 7-limit just blues, Arabic maqamat (Rast/Bayati/Hijaz/Saba) on 24-EDO quarter tones, the 22-shruti table, gamelan slendro/pelog, 31-EDO, 53-EDO and the A440 harmonic grid — onto nearest-note + RPN fine tuning, MPE 14-bit bends at ±2/±24/±48/±96 semitones, MIDI 2.0 32-bit pitch bend, the MIDI 2.0 Pitch 7.9 note attribute, and a Scala .scl export.

Finance

Side-by-side monthly rent-vs-buy simulation: mortgage amortization, property tax, insurance, HOA and maintenance against rent plus renter insurance; the renter invests the down payment and monthly savings at an opportunity-cost rate. Outputs break-even year on net sale proceeds, per-year differential NPV, SALT-cap-aware after-tax cash flows, a differential IRR, and a ±20% tornado sensitivity chart.

Development

Upload a PE-COFF (.exe/.dll), ELF or Mach-O binary and parse its headers end to end: DOS/PE signature, COFF machine, optional header (entry point, image base, subsystem, ASLR/NX/CFG), section table with RVA↔offset mapping, import/export directories, ELF program headers and PIE detection, dynamic symbols and DT_NEEDED, Mach-O load commands and dylibs — with cross-architecture annotations and a hex preview.

Utilities

Decode home and commercial electric/gas/water bills: classify tariff riders and charges (CSR/CFL/MHC/HFA-style codes, TOU on/off-peak, demand, capacity tag, decoupling), convert kWh↔Btu↔therms↔Ccf↔m³↔ton-hours with EIA factors, expose hidden fixed fees, and project annual cost with load-factor and peak-shaving savings.

Health

Plan six evidence-based breathing protocols — Wim Hof (30 breaths + retention + recovery), coherent/resonance ~5.5 bpm at the 0.1 Hz RSA peak, 4-7-8, box 4-4-4-4, Tummo-style and Buteyko reduced breathing — with a per-second timeline, capnometer-style EtCO2 trajectory model, parasympathetic/sympathetic phase marking, CP/BOLT reference and contraindication warnings.

Text Processing

Two-way Excel 365 dynamic-array workbench: expand LET/LAMBDA/MAP/SCAN/REDUCE/BYROW/BYCOL/MAKEARRAY formulas into an AST with step-traced evaluation (LET bindings, lambda first calls, intermediate matrices, optional A1-anchored sample data), and translate plain-English intents like "7-day rolling average" or "running total" into working LAMBDA/MAP/SCAN formulas.
