Native only — new capability

No compat route exists for audio effects — it wasn’t part of the old Enterprise API this compat layer mirrors. Call POST /v1/generations directly.

audio_effect — native payload

POST/v1/generationstool_id for (model, "audio_effect")

Field	Type	Required	Default	Description
song	file input	Yes	—	The track to apply effects to.
effects	array	Yes	—	An ordered chain of 1–8 effects, applied left to right. See Effect entries below.

Effect entries

Each entry in effects is {"name": "<effect name>", "params": {...}}. params is optional — omitted keys fall back to defaults. name is one of 14 values: compressor, limiter, gain, high_pass, low_pass, peak_eq, high_shelf, low_shelf, reverb, delay, chorus, phaser, distortion, noise_gate.

A few representative defaults:

{"threshold_db": -20, "ratio": 4, "attack_ms": 5, "release_ms": 100}

Any *_db param is clamped server-side to [-60, 60]; any frequency/cutoff param is clamped to [20, 20000].
