Infinite Stretch Lab PRO

Advanced Dual-Layer Granular Time-Stretch Engine

Infinite Stretch Lab PRO is a professional sound-design environment built for creating long-form textures, evolving soundscapes, cinematic atmospheres, and extreme audio transformations. Based on a dual-layer granular architecture with advanced scheduling algorithms, it enables sound designers and composers to generate deep, immersive drones and highly detailed ambient material from any audio source.

Designed for musicians, film composers, ambient artists, and experimental creators, Infinite Stretch Lab PRO delivers a modern workflow, high-fidelity processing, real-time visual feedback, and export-ready results for professional production.

Core Technology

At the center of Infinite Stretch Lab PRO is a continuously evolving granular engine. Any loaded audio file is divided into micro-fragments called grains, each with its own envelope, stereo field, smoothing, and positional behavior. By manipulating the internal playhead speed, grain duration, overlap, and pitch structure, the engine transforms even the shortest sound into extended drones, pads, or abstract textures.

Time-stretching is not achieved through traditional FFT methods; instead, it uses granular resynthesis for a more organic, evolving sonic character. The result is a uniquely smooth and atmospheric output that adapts to both subtle sound-design work and extreme transformations.

Dual-Layer Architecture

Infinite Stretch Lab PRO includes two fully independent granular engines: Layer A and Layer B.

Layer A

The primary engine, offering complete control over stretch amount, grain shaping, and pitch behavior. Ideal for core textures and long sustained material.

Layer B

A secondary, optional engine designed for additional depth and complexity. Layer B can use a different audio file, different timing behavior, and its own granular parameters. Through the A/B Mix control, both layers can be blended to create intricate multilevel drones, harmonic structures, or contrasting motion.

This dual-layer system enables everything from subtle augmentation to fully independent textural worlds operating in parallel.

Advanced Scheduling Modes

Infinite Stretch Lab PRO introduces a new concept in granular engines: algorithmic scheduling. Instead of triggering grains at fixed intervals, the engine can follow four generative timing models:

Linear

Traditional, even grain distribution for smooth continuous drones.

Fibonacci

Intervals derived from the Fibonacci sequence for organic, natural-sounding evolution.

Chaos

Non-repeating timing and position variation using chaos theory. Ideal for experimental and unpredictable textures.

Harmonic

Timing patterns based on the harmonic series, producing resonant, bell-like or overtone-rich behavior.

Each layer can use its own scheduling model, allowing highly complex motion and interplay.

Parameter System

Infinite Stretch Lab PRO provides precise control over every stage of granular synthesis, including:

Stretch – Time expansion factor and playhead slowdown

Grain Size – Length of each grain, from microscopic fragments to broad ambient swells

Overlap – Density and smoothness of grain blending

Smooth – Envelope shaping, from raw granularity to blurred, ethereal textures

Rate and Pitch – Organic pitch manipulation before and after stretching

Layer B offers a fully independent version of the same control set.

An integrated A/B Mix slider provides accurate balancing between the two engines.

Modulation, Dynamics and Monitoring

LFO System

A flexible modulation engine capable of targeting grain size, overlap, smoothing, pitch, stretch, or rate. Suitable for both slow atmospheric evolutions and more dramatic movements.

Peak Limiter

A professional limiter with adjustable threshold, ratio, attack and release. Ensures clean, controlled output even with high-density granular textures and complex dual-layer interaction.

Visualization Suite

Real-time waveform view, oscilloscope modes (Layer A, Layer B, and combined), a detailed spectrum analyzer, and limiter gain-reduction monitoring. Designed to provide clarity and accuracy during sound design.

Creative Tools and Workflow Enhancers

Freeze

Locks the playhead at a fixed position to create stable, static harmonic pads or organ-like tones. Available independently for both layers.

Randomize

Generates musically useful parameter sets for immediate experimentation and inspiration while preserving global settings such as LFO and limiter configurations.

Live Recording

Captures the processed output in real time, including limiter behavior and layer interaction. Ideal for long-form soundscapes and evolving textures.

Export Engine

Professional export capabilities including 16-bit, 24-bit and 32-bit float output, multiple sample rates, loop-safe crossfades, and true peak normalization.

Preset System

Factory presets, user preset creation, renaming, deletion and instant recall.

Professional Workflow

Infinite Stretch Lab PRO supports a wide range of workflows, from quick drone creation to advanced experimental sound design. Users can begin with a single audio file, create infinite pads using stretch and smoothing controls, then add motion with scheduling and LFO modulation. Layer B provides an additional dimension for harmonics, depth or contrast. The freeze system and visualization suite make it easy to refine the final texture before exporting or recording.

A Complete Environment for Granular Sound Design

Infinite Stretch Lab PRO is not simply a granular toy or drone generator. It is a comprehensive audio design platform with dual engines, generative scheduling, professional limiting, advanced modulation, and high-quality export tools, all inside a clean and modern interface. Whether shaping subtle cinematic atmospheres or transforming minimal material into immersive long-form compositions, Infinite Stretch Lab PRO delivers a highly refined and professional workflow suited for both studio production and experimental exploration.
