About Workflow Utilities Impulse Response

Convolves an audio file with an impulse response WAV to add reverb or another room or effect profile. `dry_level` and `wet_level` (0 to 1) set the mix. Loudness targets are adjustable through `loudness_i`, `loudness_lra` and `loudness_tp`. Output bitrate can be 128k, 192k, 256k or 320k.

Parameters

Send either the canonical name or the native name, not both. Canonical names
