Behind Sonodit's intuitive interface lies one of the most advanced digital signal processing (DSP) chains in the cloud environment. We don't just join tracks; we perform surgical voice restoration and optimisation to meet the most demanding broadcast standards for radio frequency (AM/FM) and digital systems.

Our Step-by-Step Voice Signal Chain:

• Peak and RMS Normalisation to -2dB: We adjust the voiceover gain level to set the dynamic ceiling at a strict -2dB. This ensures the signal has the maximum possible volume without risk of digital clipping or unwanted harmonic distortion.
• Spectral Removal of Noise and Artifacts: We intelligently filter out digital background noise and any bothersome low or high-frequency sounds that muddy the signal.
• Dynamic Adjustment of Silences and Breaths: The system automatically detects intrusive or overly pronounced breaths and removes them entirely. Furthermore, it calibrates the milliseconds of silence between phrases to give the voiceover a fluid, dynamic, and natural rhythm.
• Sibilance Treatment with De-esser: Annoying high frequencies produced by sibilant consonants (like "S") are attenuated using an algorithmic de-esser that smooths the signal without detracting from pronunciation clarity.
• Multiband Compression and Harmonic Enrichment: We apply frequency band-split compression to level the voice dynamics, always keeping it front and centre. Finally, we inject subtle harmonics to "sweeten" the signal, adding that warmth, weight, and presence characteristic of high-end condenser microphones in traditional studios.
