# neural-amp-modeler-lv2
|
|
|
|
Bare-bones implementation of [Neural Amp Modeler](https://github.com/sdatkinson/neural-amp-modeler) (NAM) models in an LV2 plugin.
|
|
|
|
**There is no user interface**. Setting the model to use requires that your LV2 host supports atom:Path parameters. Reaper does as of v6.82. Carla and Ardour do. If your favorite LV2 host does not support atom:Path, let them know you want it.
|
|
|
|
To get the intended behavior, **you must run your audio host at the same sample rate the model was trained at** (usually 48kHz) - no resampling is done by the plugin.
|
|
|
|
For amp-only models (the most typical), **you will need to run an impulse reponse after this plugin** to model the cabinet.
|
|
|
|
### Models and Performance
|
|
|
|
The best source of models is [ToneHunt](https://tonehunt.org/).
|
|
|
|
NAM models are generally quite expensive to run. This isn't (much of) an issue on modern PCs, but you may have trouble running on less powerful hardware.
|
|
|
|
A Raspberry Pi 4 running a 64bit OS can run "standard" NAM models with a bit of room to spare for a cabinet IR and some lightweight effects.
|
|
|
|
If you are having trouble running a "standard" model, try looking for "feather" (the least expensive) models. You can find a list of ["feather"-tagged models on ToneHunt](https://tonehunt.org/?tags=feather-mdl). Note that tagging models is up to the submitter, so not all "feather" models are tagged as such - you should be able to find more if you dig around.

### Building
|
|
|
|
First clone the repository:
|
|
```bash
|
|
git clone --recurse-submodules -j4 https://github.com/mikeoliphant/neural-amp-modeler-lv2
|
|
cd neural-amp-modeler-lv2/build
|
|
```
|
|
|
|
Then compile the plugin using:
|
|
|
|
**Linux/MacOS**
|
|
```bash
|
|
cmake .. -DCMAKE_BUILD_TYPE="Release"
|
|
make -j4
|
|
```
|
|
|
|
**Windows**
|
|
```bash
|
|
cmake.exe -G "Visual Studio 17 2022" -A x64 ..
|
|
cmake --build . --config=release -j4
|
|
```
|
|
|
|
Note - you'll have to change the Visual Studio version if you are using a different one.
|
|
|
|
After building, the plugin will be in **build/neural_amp_modeler.lv2**.
