Welcome to the official documentation for the Sonodit Audio Pipeline. Our platform takes raw voiceover files and transforms them into broadcast-ready, mastered assets through a 100% autonomous workflow. Here is the chronological journey your audio takes within our intelligent engine:

Step 1: Ingestion and Acoustic Profiling

As soon as your file enters the system, the Sonodit Audio Profiler performs a full diagnostic scan. It measures sample rate, bit depth, and calculates the initial Crest Factor. Simultaneously, a neural network maps the speaker's phonetic structure to determine their exact Words Per Minute (WPM), native language, and regional dialect. This step creates the predictive roadmap that guides all subsequent processing tools.

Step 2: Subsonic Filtering and Noise Subtraction

To ensure maximum purity, the audio enters the restoration phase. A dynamic High-Pass Filter is set at 50 Hz to eradicate rumble and parasitic frequencies that muddy the low-end. Simultaneously, the engine captures the "noise DNA" detected during pauses and applies a 50% inverse spectral subtraction algorithm, eliminating room hiss without altering the natural timbre of the voice.

Step 3: Block Stabilization (Clip Gain Matching)

One of the most complex phases: the audio undergoes a dual-stage normalization. First, the entire signal is standardized to -25.0 dB RMS. Immediately after, the system analyzes the audio phrase-by-phrase. Whether the talent whispered a line or shouted a slogan, the algorithm calculates the exact volume variance and corrects it independently, applying a +/-15.0 dB safety limit while protecting short pauses with an exclusion window. This ensures every word maintains consistent presence and commercial impact.

Step 4: Dynamic Isolation (Predictive Gating)

The stabilized audio passes through an ultra-precise noise gate set with a threshold between -50 dBFS and -55 dBFS. The system detects voice attack transients to open the signal path instantly and applies a controlled fade on word tails, burying any unwanted air or breath noise into absolute silence.

Step 5: Acoustic Modeling and Commercial Texturing

The cleaned file is automatically injected into our virtualized hardware DSP engine. Here, the audio is processed through a simulated analog rack that applies soft-knee compression, strict sibilance control (De-essing), and parallel harmonic excitation. This phase glues the signal together, giving the voice that classic "Fat and Clear" color characteristic of major radio networks and cinematic productions, with a strict peak limit set at -2.0 dB True Peak.

Step 6: Precision Segmentation and PTK Shielding

In the final stage, our temporal orchestrator (The Cartographer) takes control. If the system is set to autonomous mode, it identifies silence valleys and performs surgical cuts to export phrases as independent files. Each clip includes a 10-millisecond preemptive attack margin (PTK Protection), ensuring no leading consonants are clipped. If a unified master is requested, the system assembles the phrases by injecting dynamic silences calculated from the speaker's cadence, resulting in a tight, rhythmic, and broadcast-ready final asset.
