Behind Sonodit’s intuitive interface runs one of the most advanced cloud-based Digital Signal Processing (DSP) chains available. We don’t just merge tracks; we perform surgical voice restoration and optimisation to ensure your audio hits the professional broadcast standards required for both traditional radio (AM/FM) and modern digital platforms.

Our Step-by-Step Voice Signal Chain:

• Peak and RMS Normalisation to -2dB: We calibrate the gain levels to set a strict ceiling at -2dB. This ensures maximum loudness without the risk of digital clipping or unwanted harmonic distortion.
• Spectral Noise and Artefact Removal: We intelligently filter out digital background hum and any intrusive high or low-frequency noise that clutters the signal.
• Dynamic Silence and Breath Control: Our system automatically detects and trims intrusive breaths. It also calibrates the millisecond-gaps between phrases to give your voiceover a fluid, natural, and dynamic pace.
• De-essing for Sibilance Management: Harsh high frequencies caused by sibilant consonants (like the 'S') are smoothed out by our algorithmic de-esser, maintaining clarity without losing natural pronunciation.
• Multiband Compression and Harmonic Enhancement: We apply frequency-split compression to level the dynamics, keeping the voice front and centre. Finally, we inject subtle harmonics to 'sweeten' the signal, delivering that warmth, weight, and professional presence usually reserved for high-end condenser mics in traditional studios.
