# Pi Multi-FX Pedal — Default Cabinet IR Files
|
|
|
|
Synthetic impulse responses (.wav) for guitar cabinet simulation.
|
|
Generated using DSP filter cascades (Butterworth LP/HP + parametric
|
|
peak/notch filters + exponential decay envelope).
|
|
|
|
**All IRs are 48kHz, 16-bit mono WAV files.**

## Usage
|
|
|
|
These IRs are loaded by the `IRLoader` class through the pedal's cab simulation.
|
|
Place them in `~/.pedal/irs/` or reference them by absolute path in preset chain blocks.
|
|
|
|
## Replacement
|
|
|
|
Replace any `.wav` file with a real captured IR (48kHz, 16-bit mono) to
|
|
upgrade from synthetic to authentic cabinet tone. The pedal treats all
|
|
`.wav` files in the IR directory identically.
