Envelope Time Calculator
Calculate ADSR envelope times in samples
About this calculator
The Envelope Time Calculator converts ADSR (Attack, Decay, Sustain, Release) envelope parameters from time-based values to sample-based values for digital audio processing. This tool is essential for music producers, sound designers, and developers working with synthesizers, samplers, and audio plugins. By converting milliseconds or seconds into precise sample counts, it ensures accurate timing implementation in digital audio systems and helps maintain consistency across different sample rates and audio processing environments.
How to use
Enter your desired ADSR envelope times in milliseconds or seconds along with your project's sample rate. The calculator will instantly convert these time values into the corresponding number of samples. Use these sample values in your audio software, synthesizer programming, or digital signal processing code to achieve precise envelope timing.
Frequently asked questions
What is ADSR envelope timing?
ADSR represents Attack, Decay, Sustain, and Release phases that control how a sound evolves over time, from initial trigger to final fade-out.
Why convert time to samples?
Digital audio processing requires sample-based timing for precise control. Sample values ensure consistent envelope behavior regardless of tempo or processing variations.
How does sample rate affect the calculation?
Higher sample rates require more samples for the same time duration. 44.1kHz needs 441 samples for 10ms, while 96kHz needs 960 samples.
