downward expander static level calculator online
Use downward expander static level online for input dB, threshold dB, ratio. Hard-knee downward expansion with no time constants. Ideal mathematical audio model with supplied values. Real speakers, rooms, hearing exposure and converter performance are not measured.
How to use it
Enter input dB. Set threshold dB, ratio. Select Calculate and check the labeled output. Copy or download the JSON result.
Options and example settings
Calculation method
output_dB = max(input_dB,threshold_dB)-max(0,threshold_dB-input_dB)*range(ratio,1,1000) (^ means exponentiation; trig functions ending in d use degrees).
Worked examples
Apply downward expander static level to the case below, keeping the displayed units and assumptions. Hard-knee downward expansion with no time constants.

Output:
{
"output_dB": -60
}Choose the right tool
Choose timing tools for tempo and samples, tuning tools for frequency ratios, and level tools for amplitude or power. Coherent signal addition differs from independent-source addition; acoustic room estimates assume simplified conditions.
Limitations and common mistakes
- Hard-knee downward expansion with no time constants. Ideal mathematical audio model with supplied values. Real speakers, rooms, hearing exposure and converter performance are not measured.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
