Controls Reference
Complete parameter reference for Barometer. All 12 parameters with exact ranges and defaults from source code.
Gain & Level
| Parameter | Range | Default | Description |
|---|
| Gain | -96 to +24 dB | 0 dB | Input gain staging. -96 dB = mute. Knob centered at 0 dB (skewed for precision around unity). |
| Output Trim | -12 to +12 dB | 0 dB | Final output level after all processing. |
Phase
| Parameter | Range | Default | Description |
|---|
| Phase L | On / Off | Off | Inverts polarity of the left channel. |
| Phase R | On / Off | Off | Inverts polarity of the right channel. |
| Phase Link | On / Off | On | Links L/R phase controls — toggling one toggles both. |
Phase invert is essential for checking phase coherence in multi-mic setups. Flip one channel and listen for cancellation — if the sound gets thinner, the original phase relationship is correct.
Stereo & Routing
| Parameter | Range | Default | Description |
|---|
| Balance | -100 to +100 | 0 (center) | Stereo balance. -100 = full left, +100 = full right. |
