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 (AM/FM) and digital systems.

Our Voice Signal Chain, Step-by-Step:

• Peak and RMS Normalisation to -2dB: We adjust the gain level of the voiceover to set the dynamic ceiling at a strict -2dB level. This ensures the signal has the maximum possible loudness without risk of digital clipping or unwanted harmonic distortion.
• Spectral Removal of Noise and Artefacts: We intelligently filter out digital background noise and any bothersome low or high-frequency sounds that muddy the signal.
• Adjustment of Silences and Breaths: The system automatically detects intrusive or overly prominent breaths and removes them entirely. It also calibrates the milliseconds of silence between phrases to give the voiceover a fluid, dynamic, and natural rhythm.
• Sibilance Treatment via 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 the clarity of the pronunciation.
• Multiband Compression and Harmonic Enhancement: We apply frequency-band-split compression to level out the voice's dynamics, always keeping it at the forefront. Finally, we inject subtle harmonics to "sweeten" the signal, adding that warmth, weight, and presence characteristic of high-end condenser microphones in traditional studios.
