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.
Resource Folders
Soundshed Guitar searches these folders when building the library of models and IRs:
- Click Add Folder to include a folder on your computer (e.g. where you store your NAM model downloads).
- Click Remove to stop watching a folder.
- Click Rescan to refresh the library after adding new files manually.
NAM Calibration
Neural Amp Models carry metadata indicating what input level they were trained at. The calibration setting aligns this to your setup so the amp behaves as intended.
| Setting | What it does |
|---|---|
| Auto-Level | When enabled, input gain is adjusted automatically based on the model's calibration data. Leave this on unless you have a specific reason to disable it |
| Reference Level | The dBu level that corresponds to 0 dBFS at your interface's input. Default is +12.0 dBu. Change this if your interface has a different headroom specification |
If amps sound too compressed or too quiet, try adjusting the Reference Level up or down a few dB.
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 live input and output levels per node in the chain — 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.
