Settings
The Settings page controls how Soundshed Guitar connects to your audio hardware, where it looks for models and IRs, how it displays, and various advanced options.
Opening settings
Click the gear icon in the top-right corner of the app.
Audio Device
| Setting | What it does |
|---|---|
| Audio Device | Selects your audio interface or built-in audio device |
| Input Channel | Which socket on your interface your guitar is plugged into |
| Output Channels | Which outputs go to your monitors or headphones |
| Sample Rate | The audio sample rate (44100, 48000, 96000 Hz). Match your DAW's project rate if using as a plugin |
| Buffer Size | How many samples are processed at once. Lower = less delay (latency) but higher CPU load. 128 is a good starting point |
Click Apply after making changes. The audio engine restarts briefly.
User Input Calibration
User input calibration is the main global input-level system.
| Setting | What it does |
|---|---|
| Active Profile | Chooses which named calibration profile is applied before the signal chain |
| Train | Temporarily bypasses the active profile, watches your live input, and recommends a fixed gain offset |
| Delete | Removes a saved profile |
Each profile stores one fixed gain value. That gain is applied once before the shared pre-chain and before any preset processing.
Advanced DSP Level Targets
These settings affect final output safety and NAM calibration behavior.
| Setting | What it does |
|---|---|
| Output Protection Ceiling | Final hard safety ceiling / limiter after all processing and master gain. Prevents sending clipped audio to your interface. Default −1 dBFS. |
| Interface Calibration Level (under NAM calibration) | Your audio interface reference level in dBu. Combined with model metadata when NAM Auto Input Calibration is enabled. Default 12 dBu. |
| NAM Auto Input Calibration (toggle) | When on (default), the app sends the Interface Calibration Level to the first NAM node in the chain so it can apply automatic dBu corrections based on the model's input_level_dbu / output_level_dbu metadata. |
Changes to these settings apply immediately to the running DSP.
Theme
Choose from five visual themes:
| Theme | Character |
|---|---|
| Default | Modern, neutral dark interface |
| Light | Bright, clean look for well-lit rooms |
| Dark | Deep blacks for low-light environments |
| Classic 70s | Warm browns and amber tones |
| Worn Pedal | Weathered look inspired by vintage hardware |

Diagnostics
| Control | What it does |
|---|---|
| CPU Load display | Shows real-time CPU usage per audio block; identifies which effects are most expensive |
| Signal Level Diagnostics | Streams raw input, processed input, output, and per-node levels — useful for finding where a signal is too hot or too quiet |
| Run Signal Path Test | Sends a test tone through the chain and reports any nodes that are not producing output |
Tips
- If you experience audio dropouts (crackles, glitches), increase the buffer size by one step (e.g. 128 → 256).
- If the latency feels sluggish, try reducing the buffer size one step at a time until dropouts reappear, then step back up.
