What delay range is the Haas effect?

Roughly 1-35 ms where a delayed copy fuses with and reinforces the lead source.

How the Haas effect calculator works

Enter path difference or delay in milliseconds and temperature. The calculator converts to delay time and classifies psychoacoustic zones: fusion, precedence (Haas), and echo perception for PA and studio alignment.

Key terms

Haas effect (precedence) - short delays fuse with the lead source instead of sounding separate.
Precedence zone - roughly 1-35 ms; delayed source supports the main image.
Echo threshold - delays above ~50 ms are heard as distinct repetitions.
