Calculation method
Calculation method
Complete frames
1+floor((record length−window)/hop).
One-sided frequency bins
floor(window/2)+1.
Time spacing (seconds)
Hop/sample rate.
Frequency spacing (Hz)
Sample rate/window.
Raw grid storage (bytes)
Frames × bins × bytes per real bin.

Assumptions & limits
Assumptions & limits
- Sample rate, window-hop sizes, recording length. Returns Time-frequency bins and storage size. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Sample rate (Hz): minimum 1e-12, maximum 1000000000000.0. Window samples: minimum 2, maximum 1000000. Hop samples: minimum 1, maximum 1000000. Recording samples: minimum 2, maximum 100000000. Bytes per real-valued bin: minimum 1, maximum 16.
