Dynamic range compression is the technical process by which a processor or VST plugin reduces the volume gap between the loudest peaks and the quietest moments of an audio signal.

In the context of radio and commercial production, compression is essential for balancing the voiceover against the background music or sound bed. This ensures the message retains a solid, punchy presence, preventing it from being lost when played on small speakers, mobile devices, or in noisy environments.

Key benefits of dynamic compression for commercials:

• Consistency: Keeps the vocal performance leveled throughout the entire spot.
• Perceived Loudness: Allows the audio to sound fuller and more impactful without clipping.
• Clarity: Ensures the voice cuts through the mix, even in low-fidelity listening conditions.
