Guitar amp and pedal capture plugin using neural networks.
Capture your own amps/pedals/plugins with Proteus. Can capture a drive/tone knob, or snapshot of the sound at a specific setting. Use the Proteus Capture Utility to quickly train models in the cloud with Colab. Effective for Amps/PreAmps, Distortion/Overdrive/Boost pedals (non-time based, no Reverb/Delay/Flange/Phaser).You can also capture a „rig“, or combination of pedals/amp. This is similar in concept to a Kemper, Quad Cortex, or ToneX, in a free and open source plugin, with the ability to capture and share the sound of guitar gear normally costing hundreds or thousands of dollars.
Visit the GuitarML ToneLibrary Website to download Proteus compatible models.
Download the Proteus Capture Utility, which includes the input audio file and Colab script to train models for Proteus.
As of Version 1.2, Proteus also features a 3-Band EQ (Bass, Mid, Treble) and a built in default IR (for convenience, recommended to use a dedicated IR plugin).
Proteus uses a LSTM neural network to emulate guitar amplifiers/preamps and distortion/overdrive/boost pedals. You can capture the sound of an amplifier either by recording with a microphone, or direct out from a load box. When running „Direct Out“ models, you will need to use an Impulse Response plugin to accurately model the amp speaker/cabinet.
You can create your own models using the Automated-GuitarAmpModelling repository directly (LSTM with hidden size 40), or by using the Capture Utility files (available for download at GuitarML.com) with Google Colab (recommended).
To share your best models, email the json files to
sm***********@gm***.com
and they may be included in the ToneLibrary.
Loading models:
Download available models from the Proteus ToneLibrary. Use the Load Model button to select a folder containing Proteus json models. Note that models for NeuralPi and SmartPedal use a different model architecture and will not be compatible.
Capturing an Amp/Pedal/Plugin
Download the Proteus_Capture_Utility.zip to obtain the ProteusCapture.wav and ProteusCapture.ipynb Colab script.
Play the ProteusCapture.wav from your DAW / Audio Device and input to your amp/pedal/plugin, and record the output. Recommended to use a Reamp for impedence matching, and a Load Box for direct amp captures.
Upload the „ProteusCapture.ipynb“ from the Capture Utility to the Google Colab website. Upload your out.wav file and follow the instructions in the Colab script to create a Proteus compatible model. Snapshot model training will take 10 minutes or less, and Knob model training will take around 30 minutes. For Knob captures, you will need 5 separate out wav files, as detailed in the tutorial videos.
Download your model file (json format) and load into the Proteus plugin.
Note: Recommended to follow along with the video tutorials listed above.
You can capture amps using a microphone, which will result in the capture of the mic/cab/speaker. These captures may be less accurate than direct amp captures from a load box. Direct amp captures are also more flexible for adding Impluse Responses after the Proteus plugin.
Recommended to test a snapshot capture of your device before attempting a Knob capture. Snapshot captures are much quicker, less prone to error, and can be more accurate.
When exporting your audio recording, it needs to be WAV format, PCM16 (FP32 also acceptable), 44100 samplerate, Mono.
In Colab, the different devices listed for Step 4a,b,c are just guidelines. They start from a pre-trained model. You may be able to get better results by trying a different option for step 4.
You may use different input audio for training, either by modifying the ProteusCapture.wav or using your own. If you do this, modify the training line in Colab step 4 in the following way (using your custom file for „YourNewInput.wav“) and upload both wav files to Colab:
!python prep_wav.py $model -s ../YourNewInput.wav ../out.wav –normalize true
The sound you record is the sound the code will try to capture. Minimize noise/unwanted sounds for best results. You can also modify your recording with EQ or other effects.
