Refine (48 kHz)
Brings audio to 48 kHz. 'model' extends the top octaves with a super-resolution model and keeps everything below the crossover from the original (complementary crossover); 'resample only' converts the rate without new content. The model always runs when it is connected, also for an input that already reaches 20 kHz - nothing below the crossover changes. A prepared preset sets PRE, POST and the crossover in one go; *custom* uses the three fields. Same duration, no normalisation. Experimental.

Inputs (9)
| Name | Type | Default | Description |
|---|---|---|---|
| audio | AUDIO | The rendered song (any sample rate). | |
| engine | COMBO | resample only | model: the connected Load Audio Model (super-resolution); resample only: no model. |
| crossover_hz | FLOAT | 00–23000 | Where the model takes over; 0: 500 Hz below the measured bandwidth. |
| sr_gain | FLOAT | 1.000–2 | Level of the added band. |
| modelopt | PLENIO_AUDIO_MODEL | Load Audio Model (super-resolution); only for 'model'. | |
| presetopt | COMBO | custom - the three fields below | A prepared stage template: one choice sets PRE, POST and the crossover (500 Hz below PRE). *custom* uses the three fields below, which stay editable - the MiniMax template ships template 3 and the matching numbers. |
| pre_hzopt | FLOAT | 0-1–23000 | Low-pass before the model (it shapes only what the model sees): 0 = the model's training condition, -1 = no PRE, else Hz (6000, 8000, 10000, 12000, 14000). |
| post_hzopt | FLOAT | 00–23900 | Linear-phase roll-off of the result: 0 = off, else Hz (16000, 19000, 21000 tame added air that sounds harsh). |
| seedopt | INT | 00–4294967295 | Seed of the model: the same seed gives the same result. |
