What is a Noise Gate?

A Noise Gate is an essential dynamic processor that mutes or lowers the volume of an audio signal when it falls below a set threshold. When you record an original voiceover or a personal podcast, your microphone often picks up room tone, air conditioning hiss, or computer fan hum during the pauses between words. Our free online noise gate automatically silences these gaps, providing a clean, dead-quiet background.

What is a De-Esser?

A De-Esser is a targeted frequency compressor. Human voices naturally produce sharp, piercing bursts of high-frequency energy when pronouncing sibilant consonants like "S", "Sh", or "T". A vocal de-esser listens to these specific frequencies (usually between 4kHz and 10kHz) and instantly ducks the volume of the harsh sounds without affecting the rest of the recording, resulting in smooth, professional, and radio-ready audio.
