# Lo-fi Effects

Add grit, warmth, and character with bit crushing, folding, and distortion.

## Bit Crush

Reduce bit depth for digital artifacts:

```forth
"drum" s 8 crush .   ( 8-bit crush )
"drum" s 4 crush .   ( heavy 4-bit crush )
```

## Wave Folding

Fold the waveform back on itself for complex harmonics:

```forth
"sine" s 2 fold .    ( moderate folding )
"sine" s 4 fold .    ( aggressive folding )
```

## Wave Wrap

Wrap the waveform for a different flavor of distortion:

```forth
"bass" s 0.5 wrap .
```

## Distortion

Classic overdrive/distortion:

```forth
"guitar" s 0.5 distort .     ( distortion amount )
"guitar" s 0.8 distortvol .  ( output volume )
```

## Combining Effects

```forth
"drum" s
  12 crush
  1.5 fold
  0.3 distort
.
```
