Behind Sonodit’s intuitive interface runs one of the most advanced digital signal processing (DSP) chains in the cloud. We do more than just join tracks; we perform surgical voice restoration and optimization to meet the most demanding broadcast standards for radio (AM/FM) and digital streaming platforms.

Our Step-by-Step Voice Signal Chain:

• Peak and RMS Normalization to -2dB: We adjust the gain level 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 can clutter the signal.
• Dynamic Silence and Breath Adjustment: Our system automatically detects intrusive or overly loud breaths and removes them completely. It also calibrates the milliseconds of silence between phrases to give the voiceover a fluid, dynamic, and natural pace.
• De-esser Treatment: Harsh high frequencies caused by sibilant consonants (like "S") are attenuated using an algorithmic de-esser, smoothing the signal without sacrificing pronunciation clarity.
• Multiband Compression and Harmonic Enhancement: We apply frequency-split compression to level out the voice dynamics, keeping it upfront at all times. Finally, we inject subtle harmonics to "sweeten" the signal, providing the warmth, weight, and presence characteristic of high-end condenser microphones found in professional studios.
