Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| mixer_stateA | Full mixer snapshot: every strip and bus with label, gain, mute, routing. |
| set_strip_gainA | Set a strip's fader gain in dB (0 = unity; range -60..+12). |
| mute_stripC | Mute or unmute an input strip. |
| set_strip_routingC | Send or stop sending a strip to an output. route: A1|A2|A3|B1|B2 (kind-dependent). |
| set_bus_gainC | Set a bus (output) gain in dB. |
| mute_busC | Mute or unmute an output bus. |
| get_levelsA | Current audio levels (post-fader) per strip and bus — spot silent or clipping paths. |
| trigger_macro_buttonC | Press-and-release a Voicemeeter macro button by index. |
| load_presetC | Load a Voicemeeter settings XML preset from the local filesystem. |
| restart_audio_engineA | Restart the Voicemeeter audio engine (fixes crackle/desync; brief dropout). |
| snapshot_stateA | Save the full mixer state (gains, mutes, routing, comp/gate, EQ) to a named snapshot file (letters/digits/_/- only). Take one when the stream sounds RIGHT. |
| diff_vs_snapshotA | Compare the LIVE mixer state against a saved snapshot — answers 'what changed since the known-good config'. Snapshot must live in the snapshot directory (as written by snapshot_state). |
| set_strip_compC | Set a strip's compressor knob (0.0 = off … 10.0 = max). |
| set_strip_gateC | Set a strip's noise-gate knob (0.0 = off … 10.0 = max). |
| set_bus_eqC | Enable or disable the parametric EQ on a bus. |
| set_strip_deviceA | Bind a hardware strip to a physical input device. driver: wdm|mme|ks|asio. Hardware strips only (virtual strips have no device). |
| health_checkA | Verify connection to Voicemeeter and report kind/version. |

TDQS
Scored across 17 tools
Each tool targets a distinct aspect of mixer control (strip vs bus, gain vs mute, state vs levels, snapshot vs diff). No overlapping purposes.
All tools use snake_case with a clear verb_noun pattern (e.g., set_strip_gain, mute_bus). Even compound names like restart_audio_engine follow the same style.
17 tools is slightly high but still reasonable for a comprehensive audio mixer interface. Each tool serves a specific function without redundancy.
Covers core mixer operations (gain, mute, routing, compression, gate, EQ), presets, snapshots, and diagnostics. Minor gap: bus EQ only toggles enable/disable, no parametric control.
