Reverb Decay Time Calculator vs Long Exposure Time Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Reverb Decay Time Calculator
Calculate reverberation decay time (RT60) for a room based on its volume and acoustic absorption. Use it when designing a studio, rehearsal space, or live venue to match reverb tail length to your musical genre.
- Answers
- Optimal Decay Time (seconds)
- Inputs
- Room Volume, Absorption Coefficient, Frequency Range
Long Exposure Time Calculator
Calculates the correct long-exposure shutter speed when stacking ND filters, accounting for reciprocity failure. Use it when shooting waterfalls, light trails, or seascapes with neutral density filters.
- Answers
- Required Exposure Time (seconds)
- Inputs
- Base Shutter Speed, ND Filter Strength, Additional ND Filter, Reciprocity Failure Compensation
