Placing a music track underneath a voiceover is straightforward; getting both elements to interact organically, respecting the rhythm, intention, and narrative structure, is a feat of engineering. Sonodit's Editing Brain is the component responsible for this critical task of adaptive mixing and mastering.

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; it maps its sections (intro, development, energy build-ups, and outros) and contrasts them with the duration and pauses of the generated voiceover.

Key Features of the Editing Brain:

• Structural Editing: Cuts and splices musical bars, following the original beat's metric, so that voiceover phrase changes naturally align with music 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 voice intelligibility, maintaining the music's body and energy in the extreme ends of the spectrum.
• 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.
