# EQ & Stereo

Shape the frequency balance and stereo image of your sounds.

## Three-Band EQ

```forth
"mix" s
  3 eqlo    ( boost low shelf by 3dB )
  -2 eqmid  ( cut mids by 2dB )
  1 eqhi    ( boost high shelf by 1dB )
.
```

## Tilt EQ

A simple one-knob EQ that tilts the frequency balance:

```forth
"bright" s 0.5 tilt .   ( brighter )
"dark" s -0.5 tilt .    ( darker )
```

Range: -1 (dark) to 1 (bright)

## Gain and Pan

```forth
"kick" s 0.8 gain .     ( volume 0-1 )
"hat" s 0.5 pan .       ( pan right )
"hat" s -0.5 pan .      ( pan left )
"snare" s 1.2 postgain . ( post-processing gain )
"lead" s 100 velocity . ( velocity/dynamics )
```

## Stereo Width

```forth
"pad" s 0 width .    ( mono )
"pad" s 1 width .    ( normal stereo )
"pad" s 2 width .    ( extra wide )
```

## Haas Effect

Create spatial positioning with subtle delay between channels:

```forth
"vocal" s 8 haas .  ( 8ms delay for spatial effect )
```
