Envelope Time Calculator vs Exposure 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.
Envelope Time Calculator
Convert an ADSR envelope stage duration from milliseconds into the equivalent number of audio samples at a given sample rate. Essential when programming synthesizers or audio plugins that specify envelope times in samples rather than milliseconds.
- Answers
- Sample Count (samples)
- Inputs
- Time, Sample Rate
Exposure Calculator
Find the equivalent shutter speed when you change aperture, keeping overall exposure constant. Essential when switching f-stops mid-shoot without altering brightness.
- Answers
- Required Shutter Speed (s)
- Inputs
- Current Aperture, Current Shutter Speed, Target Aperture
