Welcome to the official documentation for the Sonodit Audio Pipeline. Our platform processes raw voiceover files and transforms them into broadcast-ready, mastered assets entirely autonomously. Below is the chronological journey your audio takes within our intelligent engine:

Step 1: Ingestion and Acoustic Profiling

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

Step 2: Subsonic Filtering and Noise Subtraction

To ensure maximum clarity, the audio enters the restoration phase. A dynamic High-Pass Filter is applied at 50 Hz to eliminate parasitic frequencies that muddy the low end. Simultaneously, the engine captures the 'noise floor fingerprint' from the speaker’s pauses and applies a 50% inverse spectral subtraction algorithm, removing room hiss without affecting the natural timbre of the voice.

Step 3: Block Stabilization (Clip Gain Matching)

One of the most complex phases: the audio undergoes double normalization. First, the full signal is standardized to -25.0 dB RMS. Immediately after, the system analyzes the audio phrase by phrase. If the voiceover artist whispered a line or shouted a slogan, the algorithm calculates the exact gain variance and corrects it independently, applying a safety limit of +/-15.0 dB while protecting short gaps with an exclusion window. This ensures every word carries consistent presence and commercial impact.

Step 4: Dynamic Isolation (Predictive Gate)

The stabilized audio passes through an ultra-precise noise gate configured between -50 dBFS and -55 dBFS. The system detects the voice’s attack transients to open the signal flow instantly and applies a controlled fade on the tails of words, suppressing any residual breath or background noise into absolute silence.

Step 5: Acoustic Modeling and Commercial Texturing

The cleaned file is automatically injected into our virtualized hardware engine (DSP Engine). Here, the audio is processed via a simulated analogue rack that applies soft-knee compression, strict sibilance control (De-esser), and parallel harmonic excitation. This phase glues the signal together and gives the voice the classic 'Fat and Clear' sound characteristic of major radio networks and cinematic productions, with a strict True Peak ceiling of -2.0 dB.

Step 6: Precision Segmentation and PTK Shield

In the final stage, the temporal orchestrator (Cartographer) takes control. If working in autonomous mode, it locates silence gaps and performs perfect cuts to export phrases as independent files. Each cut includes a 10ms pre-attack buffer (PTK Protection), ensuring no starting consonants are clipped. If a unified master file is requested, the system assembles the phrases by injecting dynamic silences calculated from the speaker's natural rhythm, resulting in a compact, rhythmic piece ready for airplay.
