Praat AudioTools – Detailed Script Overview

Bayesian Drone Weaver

Algorithmic drone composition: Bayesian classification of audio clips into gesture types, intelligent timeline construction, and overlapping assembly for continuous ambient textures.

Causal Recomposer

A grain re-ordering processor that fits a compact predictive law between local intensity and spectral centroid, then uses the residual from that model as a stable sort key. The source is reduced to one protected mono grain pool and recomposed twice — left and right use the same primary causal sort plus a few channel-specific local swaps to create stereo from recomposition itself.

Chaotic Neural Map Modulator

Content‑aware chaotic modulation. A small MLP is trained on feature streams from the input, iterated with controlled instability, and its output modulates pitch, amplitude, and ring‑frequency. Pitch modulation is relative to the input’s tracked F0 contour and quantized to a chosen scale; ring‑modulation locks to harmonic ratios of local F0; unvoiced frames skip pitch‑shift entirely; modulation depth reduces near transients.

Cross-Entropy Concatenative Mosaicing

Sound P (source palette) is sliced into frames, each normalised into a spectral PDF. Sound Q (target template) is sliced similarly. For every Q frame, the script searches the entire P library and selects the frame whose PDF minimises the cross-entropy against Q's PDF. The winning P-frames are concatenated in Q's temporal order, producing a resequencing of P's timbral material that tracks Q's spectral progression.

CWT Granular Resampler

Takes two Sounds: A (analysis) and B (grain source). Significant pooled |CWT(t,f)| cells from A generate an expected number of grains from B; fractional counts are realised stochastically. Each grain is read from B at a playback-rate ratio derived from the firing wavelet bin, with duration scaled by that bin's frequency. The result maps A's time–frequency morphology onto B's timbral material.

Gesture-Based Hard Quantization

Concatenative gesture quantization: segment a reference sound, match each segment to a canonical dictionary atom in a normalized pitch/voicing/intensity feature space, and reconstruct the timeline with a nearest-neighbour leader plus optional stochastic polyphonic layers.

Gestural Accumulator

Compositional canon generator: creates accumulating variants of a sound gesture, arranges them via acoustic distance scheduling to form evolving sonic narratives.

Genetic Recomposer

Evolutionary audio recombination: uses genetic algorithms to automatically slice, reorder, and reassemble audio segments, evolving new sonic organisms through fitness-based selection.

Granular Attention Resynth

Attention-weighted self-resynthesis: candidate grains are scored, hard-gated, and sampled from an active-only softmax distribution. Low alpha gives a broad self-remix; high alpha concentrates repeatedly on the strongest surviving grains.

Hidden Markov Model Timbre Sequencing

A 5D diagonal-Gaussian Hidden Markov Model for timbre-state resequencing: k-means initialization, Viterbi hard-EM training, stochastic state generation, Gaussian or uniform within-state frame selection, and fixed-hop normalized Hann overlap-add synthesis.

KL Divergence Corpus Resynthesis

Corpus A defines a target timbral distribution. Corpus B provides source grains. The script greedily builds an output by selecting grains that minimise KL divergence between the reference distribution and the growing output distribution — actively driving synthesis, not just analysing afterwards.

LZ-Inspired Audio Variations

Lempel–Ziv-based audio variation: overlapping audio windows are quantized into a symbol sequence, parsed into a variable-length LZ78 phrase dictionary, and recombined as contiguous source runs for transformation and resynthesis.

Markov Soundscape Weaver

Phase Modulation Matrix

Layered sinusoidal time displacement: each processing layer adds a time-shifted copy of the current signal, using a different modulation rate and depth, then passes the accumulated result into the next layer.

Polyphonic Improviser

Divides one source into equal chunks, independently shuffles those chunks for 2–4 delayed voices, transforms each voice by varispeed or pitch-preserving time scaling, joins the chunks with fixed 40% equal-power overlap, and pans the resulting mono voices into a newly generated stereo texture.

Quantum State Superposition

A quantum-inspired, fully classical audio processor that cascades noncausal three-tap FIR states. Each state combines the current signal with past and future sample-offset taps, rotates the two delayed-tap coefficients with cosine/sine weights, applies a state-position wet weighting, and changes the superposition strength from state to state.

Algorithmic ensemble conductor with sample‑level rendering. Select 2+ Sound objects – the conductor assigns dynamic roles (leader, shadow, resonance, noise fringe, pulse carrier, interruption, sustain bed, contrast voice, memory trace, silence) and states (sparse, balanced, agitated, saturated, suspended, released) to segments of each file. A stereo mix is rendered continuously in Python – click‑free, no segmentation artefacts.

Latent Folding

Treats the learned latent audio space as a deformable manifold. Three topologies: Mirror (reflection), Möbius (twist/inversion), Torus (seamless wrap). As the observer traverses the space, boundaries fold or invert acoustic identity — not time-reversal, but identity-reversal. Creates "Recursive Spectralism."

The CNN learns a latent morphology space of events, clusters them, computes dramaturgical scores, and returns a montage plan for reassembly.

RF Concatenative

A multi-target Random Forest models local feature-state transitions X_t → X_{t+k}. Its prediction is blended with a synthetic target trajectory in standardised corpus space, then matched against a grain pool by L2 distance.

Rhythmic Voice Flattener

Compositional Voice Transformer. Flattens pitch to a centre frequency and rebuilds the audio as a formally shaped composition where musical interest arises from rhythm, timing, silence, density, grouping, accent, and gesture structure – not melody.

Self-Attention Latent

VAE encode → self-attention → navigation plan → output. No external models, no internet, pure NumPy. The system segments audio into events, trains a lightweight VAE, builds a self-attention matrix, generates a navigation plan with four phases (drift, mutate, return, settle), and executes it to produce a new timeline.

Self Reflective Feedback

Single-stage self-reflective feedback loop. Praat runs a chosen transformation, exports a preview, Python analyzes it and returns updated parameters, and the process repeats until metrics stabilise or max_iter is reached. Supported stages: MDS Space Navigator, Spectral Freeze & Glitch, Crystalline Cascade, 4-Channel Canon.

Semantic Timbre Retrieval

Free‑text timbre search over a corpus of audio files. Type a prompt like “dark airy swelling scrape” – the engine analyses the corpus, extracts 8 semantic dimensions (brightness, noisiness, tonalness, stability, impulsiveness, sustain, roughness, spatiality), applies rule‑based tagging, and retrieves the best‑matching files or segments using hybrid scoring (semantic + tag + keyword). Returns a ranked list and an optional preview montage.

Praat reassembles events with crossfade.

Sympathetic Resonance

Virtual string physical model. Discovers the latent pitch collection embedded in a source sound, builds a bank of virtual resonant strings tuned to that discovered scale, and excites them with the source. The result is the sympathetic resonance aura: a glowing image of the sound as if it had excited a giant metallic, glassy, wooden, or airy resonant body.
