# WT WAVE TERRAIN SYNTHESIS USING PERLIN NOISE
WT is a powerful tool (in python) for generating and manipulating sounds through wave terrain synthesis, where surfaces are shaped using Perlin noise.
>*terrain generation*
```python
from terrain import Terrain
terrain = Terrain(size=(WIDTH, HEIGHT), xy_incr=(0.01, 0.01))
```
>*generate envelope*
```python
from envelopes import EnvelopeTypes, Envelope
envelope = Envelope(
envelope_type=EnvelopeTypes.ADSR,
dur=ENVELOPE_DUR,
sr=SR,
atk=0.001,
decay=0,
release=ENVELOPE_DUR - 0.001,
sustain_amp=1.0,
initial_amp=0.0001,
end_amp=0.0001,
mode="exp"
)
envelope.show_env()
```
>*generate orbit and add envelope to orbit*
```python
from orbits import OrbitTypes, Orbit
orbit = Orbit(orbit_type=OrbitTypes.SPIRAL, center=(0.5, 0.5))
orbit.envelope = envelope
orbit.show_orbit(period=1 / SR)
```
>*wave terrain synthesis*
```python
from wave_terrain import WaveTerrainSynthesis
wt = WaveTerrainSynthesis(sr=SR)
wt.terrain = terrain
wt.orbit = orbit
```
>*generate sample by sample*
```python
y = np.zeros(SAMPLE_DUR, dtype=np.float64)
for i in range(SAMPLE_DUR):
sample = wt.get_sample(freqs=(FREQX, FREQY), haptic_freq=HAPTIC_FREQ, max_r=0.707)
y[i] = sample
# master envelope
y *= np.hanning(SAMPLE_DUR)
```
