For the open models people name for dialogue cleanup (DeepFilterNet, Resemble Enhance, Demucs/HTDemucs), what inputs, outputs, controls and sync/level behaviour do their repositories document or imply, what do they actually claim about dialogue, and what are the per-component licences?

At pinned commits: DeepFilterNet is a 48 kHz real-time noise suppressor whose Python CLI compensates its STFT delay by default while the Rust binary only does so with -D; Resemble Enhance averages to mono, works at 44.1 kHz, processes long audio in overlapping 30 s chunks with per-chunk peak normalisation and cross-correlation re-alignment, and is described as also restoring distortions and extending bandwidth; Demucs documents music stems only and its README (searched) never mentions speech or dialogue, so "Demucs for dialogue" is not a documented use. The Cocktail Fork paper is the film-relevant separation reference, but evaluates on synthetic single-channel mixes. Code licences are stated (MIT, or MIT/Apache-2.0); weights licences are stated only for Resemble (card says MIT), not DeepFilterNet or Demucs. Curator qualifications: All 37 excerpts located. Curator checked dfn_rust_enhance_wav.rs: delay = fft_size - hop_size + lookahead*hop_size, trimmed only 'if args.compensate_delay' (flag short = 'D'), and non-model-rate input is resampled (conflict with README '48kHz only' kept). dfn_enhance.py: '--no-delay-compensation' sets dest compensate_delay, so the Python CLI compensates by default. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
