Placing a music track under a voiceover is a simple task; making both elements interact organically, respecting the rhythm, intention, and narrative structure, is a feat of engineering. Sonodit's Edit Engine is the component responsible for this critical adaptive mixing and mastering task.

When you select a music track for your ad spot, Sonodit's engine performs an immediate analysis of its transients and calculates the exact BPM (Beats Per Minute) of the piece. The system doesn't just loop the music flatly; it maps its sections (intro, development, energy swells, and outros) and contrasts them with the duration and pauses of the generated voiceover.

Key Features of the Edit Engine:

• Structural Editing: Cuts and stitches musical bars following the original rhythm's meter, so that the voiceover's phrase changes naturally align with the music's transitions.
• Dynamic Frequency Attenuation: Instead of simply lowering the music's overall volume when the voice speaks (traditional ducking), Sonodit specifically attenuates frequencies that compete with the voice's intelligibility, maintaining the music's body and energy intact at the spectrum's extremes.
• Professional Multi-Format Export: Once the mix is consolidated, the engine performs a high-fidelity render, delivering the final product simultaneously in WAV (uncompressed, ideal for archiving and editing in broadcast automation systems) and MP3 (optimized encoding for fast distribution and streaming) formats.
