How is compression ratio calculated
Web12 jul. 2024 · A gain ratio is just the relationship between input and output level. Most compressors have 2:1, 4:1, and 8:1 ratio settings, with some going all the way to 20:1. At 2:1, for every 2 dB of input signal, 1 dB is outputted. So with 10 dB of input signal at a 2:1 ratio, 5 dB is the output. The principle is the same for every ratio: at 4:1, for ...
