nvrl	c06d193b18	feat(planish): add Planish harmonic OTT ... Upward and downward compression in four bands whose edges are harmonic numbers of the tracked note (default 1, 2-4, 5-16, 17 and up), so the same setting squashes the same harmonics on every note. A fixed-band OTT puts harmonic 2 of F1 and of C2 in different bands. - Three Linkwitz-Riley splits at sqrt(k(k+1)) x f0 with allpass compensation; at Depth 0 the bands sum within 0.05 dB. - Band level is the RMS over one period of the note, so heavy settings do not ripple at f0: a 40 Hz sine at Drive +12 dB, Time 10 % gets no harmonics above -110 dB. - At Depth 100 % on a saw, harmonics 1-12 change by the same amount on F1, C2 and G2 (within 0.2 dB). - Depth, Drive (on the detector only), Upward, Downward, Time, a gain per band; edges Low 1-8, Mid 2-16, High 3-48 with four splits. - Pitch from audio with about 67 ms lookahead, or from MIDI. - Editor: harmonic ruler with draggable edges, level and gain per band. - Catalog, workflows, editor-check, docs, signal chain and site copy.	2026-11-06 12:51:49 +01:00
nvrl	839e46aec9	docs: signal chain guide and suite audit ... docs/chain.md gives the plugin order for a bass track and the bus, the latency each plugin adds, and the measured octave error of downstream note trackers after Knurl: from C2 up the tracker reads an octave low about 85 % of the time, and timing jitter adds 5-25 false note starts per second. Knurl and Anvil guides point there and recommend MIDI as the pitch source after Knurl. docs/ideas.md gains the production-flow audit, next steps for every released plugin, new ideas (Forge, Planish, Quench, Scribe, Bevel, Peen) and a build order.	2026-11-06 12:24:10 +01:00
nvrl	5cc3770737	feat(knurl): add Knurl cycle texture ... Knurl follows the played note and treats every cycle of the wave on its own: a repeating level pattern over 1-16 cycles makes subharmonics in tune with every note, random level and timing per cycle add rattle, and a noise burst per cycle, highpassed at a multiple of f0, adds grit. Amounts are counted in cycles, so the texture is the same on F1 and on C2. - Cycle clock from the shared note tracker, restarted at each note; the audio is delayed by the lookahead plus 4.2 ms of timing-jitter headroom. - Per-cycle randomness from a hash of the cycle number: Same every note or Free. - Patterns Off, Double, Triple, Fry (default), Gallop, Stutter or drawn; grit switchable per step. Pattern persisted as knurl-pattern. - Editor: last eight cycles overlaid, pattern bars with the playing step. - Tests match the prototype: Double gives f0/2 at -8.19 dB, Triple f0/3 at -10.68 dB, equal on F1 and C2, no added clicks, bit-exact when off, no allocation on the audio thread.	2026-11-06 08:49:11 +01:00
nvrl	9b3ddeaf56	feat(weld): phase alignment for layered bass, release 0.1.0 ... Weld hears the other bass layer through the sidechain and fits polarity plus up to four RBJ allpass sections to the measured cross-spectrum, so the layers sum instead of cancelling. No latency; the layer on its own keeps its sound. - Worker thread: Welch cross-spectrum and coherence, Nelder-Mead fit with 1/f weighting, a per-band loss penalty and model selection by share of the achievable gain; GCC-PHAT lag detection flags a late layer. - Audio thread: allocation-free chain with a 40 ms warm-up and 40 ms crossfade per new fit; mono blocks go to the worker through a lock-free queue. - Follow / Learn / Hold; the fit is persisted and restored without a crossfade. - Editor: per-band loss and recovery against a perfect alignment, phase before and after, recovered dB, time offset and status. - Tests for flat magnitude, crossfade, fit targets, Follow hysteresis, Learn, silence, realtime allocation and the persisted fit in the host.	2026-11-06 08:31:41 +01:00
nvrl	0a0917ac56	chore: rename the suite to Bass Foundry ... Set the CLAP vendor of all seven plugins to "Bass Foundry" and name the combined preview ZIP bass-foundry-windows-x86_64.zip. CLAP IDs and saved state stay unchanged. Bring development.md and releases.md up to date with all seven products, the shared crates, the test types, the steps to add a product and the published releases. Add texture problems and seven texture plugin ideas to ideas.md.	2026-11-06 08:01:02 +01:00
nvrl	b3ebe4d952	feat: add Lathe harmonic EQ and Temper tracked distortion ... Lathe places EQ bands on harmonics 1-32 of the played note, so a cut on harmonic 3 stays on harmonic 3 on every note. Temper normalises each note's level before an oversampled shaper and tunes its floor, push and bright filters to the note, so every note distorts the same. The note tracker moves from Anvil into common-dsp, together with a state-variable filter, 4x oversampler and harmonic meter. Anvil's behaviour and editor render are unchanged. docs/ideas.md collects all plugin ideas and their status.	2026-11-06 06:08:51 +01:00
