# Space & Time

Spatial effects position sounds in the stereo field and add depth through delays and reverbs.

## Pan

Pan positions a sound in the stereo field.

```forth
hat -0.5 pan .               ( slightly left )
perc 1 pan .                 ( hard right )
kick 0 pan .                 ( center )
```

| Parameter | Range | Description |
|-----------|-------|-------------|
| `pan` | -1 to 1 | Stereo position (-1 = left, 0 = center, 1 = right) |

## Width

Width controls the stereo spread using mid-side processing.

```forth
pad 1.5 width .              ( wider stereo )
pad 0 width .                ( mono )
```

| Parameter | Range | Description |
|-----------|-------|-------------|
| `width` | 0+ | Stereo width (0 = mono, 1 = unchanged, 2 = exaggerated) |

## Haas Effect

The Haas effect delays one channel slightly, creating a sense of stereo width and spatial placement.

```forth
snare 15 haas .              ( 15ms delay on right channel )
```

| Parameter | Range | Description |
|-----------|-------|-------------|
| `haas` | ms | Delay time (1-10ms = subtle width, 10-35ms = distinct echo) |

## Delay

Delay is a send effect that creates echoes. The `delay` parameter sets how much signal is sent to the delay bus.

```forth
snare 0.3 delay 0.25 delaytime 0.5 delayfeedback .
```

| Parameter | Range | Description |
|-----------|-------|-------------|
| `delay` | 0-1 | Send level |
| `delaytime` | seconds | Delay time |
| `delayfeedback` | 0-0.95 | Feedback amount |
| `delaytype` | type | Delay algorithm |

### Delay Types

| Type | Description |
|------|-------------|
| `standard` | Clean digital repeats |
| `pingpong` | Bounces between left and right |
| `tape` | Each repeat gets darker (analog warmth) |
| `multitap` | 4 taps with swing control via feedback |

```forth
snare 0.4 delay pingpong delaytype .
pad 0.3 delay tape delaytype .
```

## Reverb

Reverb is a send effect that simulates acoustic spaces. The `verb` parameter sets the send level.

```forth
snare 0.2 verb 2 verbdecay .
pad 0.4 verb 4 verbdecay 0.7 verbdamp .
```

| Parameter | Range | Description |
|-----------|-------|-------------|
| `verb` | 0-1 | Send level |
| `verbdecay` | seconds | Reverb tail length |
| `verbdamp` | 0-1 | High frequency damping |
| `verbpredelay` | ms | Initial delay before reverb |
| `verbdiff` | 0-1 | Diffusion (smears transients) |
| `verbtype` | type | Reverb algorithm |

### Reverb Types

| Type | Description |
|------|-------------|
| `dattorro` | Plate reverb, bright and metallic shimmer |
| `fdn` | Hall reverb, dense and smooth |

```forth
snare 0.3 verb dattorro verbtype .   ( plate )
pad 0.5 verb fdn verbtype .          ( hall )
```

## Comb Filter

The comb filter creates resonant pitched delays, useful for Karplus-Strong string synthesis and metallic tones.

```forth
white 0.5 comb 220 combfreq 0.9 combfeedback .   ( plucked string )
```

| Parameter | Range | Description |
|-----------|-------|-------------|
| `comb` | 0-1 | Send level |
| `combfreq` | Hz | Resonant frequency |
| `combfeedback` | 0-0.99 | Feedback (higher = longer decay) |
| `combdamp` | 0-1 | High frequency damping |

Higher feedback creates longer, ringing tones. Add damping for more natural string-like decay.
