Gate Threshold Calculator
Calculate noise gate threshold from signal levels
About this calculator
A gate threshold calculator helps audio engineers and producers determine the optimal noise gate settings for removing unwanted background noise while preserving desired audio signals. By calculating the precise threshold level based on your signal and noise floor measurements, this tool ensures clean recordings without cutting off quiet passages or letting through unwanted ambient sound, making it essential for professional audio production and podcast editing.
How to use
Enter your desired signal level (the audio you want to keep) and your noise floor level (background noise to eliminate). The calculator will determine the optimal gate threshold setting that sits between these values, typically closer to the noise floor to ensure effective noise reduction while maintaining signal integrity.
Frequently asked questions
What is a noise gate threshold?
The threshold is the audio level below which the gate closes, silencing any signal quieter than this setting to eliminate background noise.
How do I measure my noise floor?
Record a few seconds of silence in your recording environment and check the peak levels on your audio meter or DAW.
Should the threshold be closer to signal or noise level?
Set the threshold closer to the noise floor but above it, typically 3-6 dB higher than your measured background noise level.
