lambdasim

Python library to interact with Lambda (FDTD acoustic simulations)

Features

• Read and write simulations
• Create complex simulation setups using vector shapes
• Embed sampled sources in a simulation
• Convert sensor data to audio
• Calculate real-world dimensions of simulation
• Preset shapes like tubes, bells, resonators
• Precalculation of dead nodes to speed-up calculations

Installation

1. Install Lambda. Download binaries or install from source

2. Clone this repo:

   $ git clone https://github.com/gesellkammer/lambdasim
   

3. Install it:

   $ pip install -r requirements.txt
   $ python setup.py install
   

Dependencies

• shapely
• shapelib
• bpf4
• sndfileio
• rasterio

Examples

The simplest simulation:

import lambdasim
# a simulation space of 4mx3m with resolution of 1 cm
sim = lambdasim.Simulation((4, 3), resolution=0.01)
# attach a source
sim.source_point(2, 1.5, 'sin', freq=440, amp=0.3)
sim.write("simplesine")
sim.opensim()
