| beam | Beam: free-free ends in the page (Ends 'free'; rigid part of strikes removed and reported; mode displays by Modes.count; bending offsets for ghost and Lyapunov shadow; drawing without supports) | |
| common | Note renderer: step at the stability step and read the signal between steps by cubic interpolation (no longer at least 4 steps per audio sample); plate notes 1.4-2.3x faster | |
| double-pendulum | Spectrogram: log frequency axis by default with a 'log f' chip for linear; rows show the loudest bin in their band; mode lines decided per line | |
| fput-chain | Anti-alias filter for rendered notes (beam, fput-chain): 4x oversampling, Kaiser FIR low-pass to 0.42 fs, decimation; beam warning now says modes above the passband are filtered out | |
| plate | Plate: optional curvature (domed rest shape, Marguerre shallow shell): stretching measured from the rest shape, computed modes with the curvature stiffness, generalized nonlinear scale | |
| index.html | Plate: remove membrane tension (did not sound like a drum; drums later); clamped edges stay | |
