Once uploaded, your files are:

  4. Tap "USE MY OWN" button

Supported File Formats

Type Format Notes
NAM Models .nam NAM A2-Lite format
Impulse Responses .wav Truncated to 1024 samples on device

Note: IR files are automatically truncated to 1024 samples for optimal performance on Stratus. This provides excellent sound quality while keeping CPU usage low (~19.4%).


Adding Custom Images

When uploading, you can optionally add a custom image for your NAM model or IR. This helps you identify your uploads in your library.

Image tips:

  • Square images work best
  • Keep file size reasonable for faster loading
  • Use images that represent the amp or cab

If you don't add an image, a default placeholder will be used.


Where to Find NAM Models & IRs

Free NAM Models:

  • TONE3000 — 300,000+ free captures (also available directly in the app!)
  • ToneHunt — Community NAM captures
  • r/NeuralAmpModeling subreddit

Syncing Across Devices

Uploads are automatically saved to your Chaos Audio account, so:

  1. Upload a NAM model on your phone
  2. Log in on your tablet
  3. Your uploaded NAM model is already there!

This makes it easy to prepare your sounds on one device and use them on another.


Installing to Stratus/Nimbus

After uploading, you still need to install the effect to your pedal:

  1. Find your uploaded file in the NAM AMP MODELS or IMPULSE RESPONSES category
  2. Make sure Stratus/Nimbus is connected via Bluetooth
  3. Tap "Install"
  4. Wait for the Bluetooth transfer to complete

Tip: The "Install" button shows a gradient color if the effect isn't installed yet.


Troubleshooting

Can't find the .nam/.wav file on my device? → Make sure the file is saved to a location your device can access (Downloads folder, iCloud Drive, Google Drive, etc.)

Upload failed? → Check your internet connection and try again. Large files may take a moment to upload.

NAM model doesn't sound right? → Some NAM captures require specific input gain staging. Adjust the Input control on the NAM effect.

IR file rejected? → Make sure it's a valid .wav file. Some IR files may use unsupported sample rates — try a different IR.
