Crate plato_audio_jepa 

plato-audio-jepa

Audio / vibration JEPA for the PLATO nervous system. Processes microphone input into structured room state vectors suitable for downstream tiles.

Structs

AudioDeadband

Spectral deadband filter — only process chunks when frequency content changes.

AudioTile

Structured room state produced by the audio JEPA from a chunk of audio.

RoomAudioState

16-dimensional audio state vector for a room.

Functions

audio_state_to_tile

Convert a RoomAudioState into an AudioTile (the output artifact).

compute_band_energy

Compute the energy (sum of squares) in a frequency range.

compute_onset_rate

Estimate the onset rate (sudden volume increases per unit time) from a volume history. Returns the rate of onsets.

compute_spectral_centroid

Compute the spectral centroid (weighted mean of frequency bins). Returns a value in the range of the spectrum magnitudes.

compute_spectrum

Compute a simple DFT returning the magnitude of the first 16 frequency bins. Input is a window of time-domain samples (ideally power-of-2 length).

detect_rhythm

Estimate BPM from a volume envelope by counting peaks. sample_rate is the rate of the volume-history samples (not audio samples).
