avnd_tools::EntityToMidi::synth_state Struct Reference

Detailed Description

Per-id bookkeeping for entities that arrive as bare positions: what the source does not send (age, velocity) is differenced from these.

Member Data Documentation

f_vx

ossia::one_pole_filter<float> avnd_tools::EntityToMidi::synth_state::f_vx

Mean velocity, against which the deviation that defines agitation is measured: a fast but steady walk is not agitated, a slow fidget is.

last_dt

double avnd_tools::EntityToMidi::synth_state::last_dt = 0.

Seconds since the previous frame this entity appeared in. Recorded by parse_entities before it advances time, because the analysis runs afterwards and would otherwise only ever see a zero interval.
