Behind Sonodit's intuitive interface runs one of the most advanced digital signal processing (DSP) chains in the cloud. We don't just stitch tracks together; we perform surgical restoration and optimization of the voiceover to meet the most demanding broadcast standards for radio (AM/FM) and digital systems.

Our Voice Signal Chain Step-by-Step:

• Peak and RMS Normalization to -2dB: We adjust the gain levels of the voiceover to set the dynamic ceiling at a strict -2dB. This ensures the signal achieves maximum loudness without the risk of digital clipping or unwanted harmonic distortion.
• Spectral Noise and Artifact Removal: We intelligently filter out digital background noise and any distracting low or high-frequency sounds that may clutter the signal.
• Dynamic Silence and Breath Adjustment: The system automatically detects intrusive or overly loud breaths and removes them entirely. Furthermore, it calibrates the milliseconds of silence between phrases to provide a fluid, dynamic, and natural pace to the performance.
• De-esser Sibilance Treatment: Harsh high frequencies produced by sibilant consonants (such as "S" sounds) are attenuated via an algorithmic de-esser, smoothing the signal without sacrificing clarity or diction.
• Multiband Compression and Harmonic Enhancement: We apply frequency-banded compression to level out the voice dynamics, keeping the narration front and center. Finally, we inject subtle harmonics to "sweeten" the signal, providing the warmth, weight, and presence characteristic of high-end condenser microphones found in traditional professional studios.
