dynamic-sound 1.0.1

Add your description here

DynamicSound is a modular Python library designed for generating virtual acoustic scenes with customizable microphone configurations, sound sources, and environmental conditions. It is intended for research, algorithm development, and testing in areas such as beamforming, source localization, audio augmentation, and acoustic machine learning.

🚀 Features

• Flexible microphone models

  • Single-channel microphones
  • Microphone arrays with arbitrary geometry
  • User-defined sampling rates

• Configurable sound sources

  • White noise generator
  • Sinusoidal signal generator
  • Audio file source

• Environmental modeling

  • Source and microphone trajectories, 3D positions and rotations
  • Air absorption based on ISO 9613-1
  • Temperature, pressure, and humidity parameters

• Signal path simulation

  • Distance-based attenuation
  • Multiple sound sources simulation
  • Scenarios with dynamic movement

🔢 Versioning

This library follows Semantic Versioning using the format M.m.p

Where:

• M – Major version: incompatible API changes
• m – Minor version: added functionality in a backward-compatible manner
• p – Patch version: backward-compatible bug fixes

📦 Installation

From PyPI

pip install dynamic-sound[==<version>]

example: pip install dynamic-sound=1.0.0

🎮 Usage Example

import dynamic_sound as ds

source_path = ds.Path([
  # time / position(x,y,z) / quaternion(w,x,y,z)
    [0.0,  343, 3, 1,   1, 0, 0, 0],
    [10.0, -343, 3, 1,   1, 0, 0, 0]
])
microphone_path = ds.Path([
    [0.0,  0, 0, 1,   1, 0, 0, 0],
    [10.0,  0, 0, 1,   1, 0, 0, 0]
])

# simulation environment
sim = ds.Simulation(
    temperature=20,  # temperature [°C]
    pressure=1,  # pressure [atm]
    relative_humidity=50  # relative humidity [%]
)

# microphone
mic_sample_rate = 48_000  # Hertz [Hz]
microphone = ds.microphones.Microphone("_tmp/sine_dynamic.wav", sample_rate=mic_sample_rate)
sim.add_microphone(path=microphone_path, microphone=microphone)

# source
source = ds.sources.SineWave(frequency=2_000, amplitude=1.0)
sim.add_source(
    path=source_path,
    source=source
)

sim.run()
