houdini-chops
Typed CHOP tools for agents. All tools are affinity: main.
Tool groups
network: create_chop_network — create and manage CHOP container networks.motion: create_motionclip — import or create motion clip CHOPs for
animation data.audio: create_audio_driven — set up audio-driven animation channels
using Audio/Envelope CHOPs.filter: apply_filter — apply procedural CHOP filters (lag, spring,
noise, smooth).export: export_to_keyframes — bake CHOP channel data to object
keyframes.inspect: get_channel_info — inspect CHOP node channels (names, sample
rate, length, value range).

create_audio_driven can point at a .wav file or use an existing audio node.
The envelope follower produces amplitude-driven channels that can be wired to
any object parameter.
