Signal Chain Calculator — Cumulative Gain & Noise Analysis
Calculate cumulative gain and noise through a series of audio components.
How We Calculate This
The signal chain calculator sums the gain (in dB) through each stage to find the total gain and output level.
Noise is calculated using a simplified version of the Friis formula, where each stage's noise contribution is referred back to the input and then amplified by the total chain gain.
Total gain = sum of all stage gains (dB)
SNR = output signal level − output noise floor
