LabSoundPy Examples

This directory contains example scripts demonstrating how to use the LabSound Python bindings.

Running Examples

You can run the examples directly using Python:

# Run the simple oscillator example
python examples/simple_oscillator.py

# Run the NumPy processing example
python examples/numpy_processing.py

Example Descriptions

Simple Oscillator (simple_oscillator.py)

This example demonstrates the basic usage of LabSoundPy. It creates a sine wave oscillator, connects it to a gain node, and plays it for 2 seconds.

Key concepts demonstrated:

• Creating an AudioContext
• Creating and configuring nodes (OscillatorNode, GainNode)
• Connecting nodes
• Starting and stopping audio playback
• Using the context manager for resource management

NumPy Processing (numpy_processing.py)

This example demonstrates how to use NumPy for audio processing with LabSoundPy. It creates a function node that applies a sine wave modulation to the input signal.

Key concepts demonstrated:

• Creating a FunctionNode for custom audio processing
• Converting audio buffers to NumPy arrays
• Applying NumPy-based signal processing
• Updating audio buffers in-place
• Maintaining state between processing callbacks

Creating Your Own Examples

When creating your own examples, follow these guidelines:

1. Start with an AudioContext using the context manager (with statement)
2. Create and configure the necessary nodes
3. Connect the nodes to form a processing chain
4. Start audio playback
5. Wait for the desired duration
6. Stop audio playback
7. Clean up resources (handled automatically by the context manager)

Dependencies

The examples require:

• Python 3.7+
• LabSoundPy installed (either in development mode or from a package)
• NumPy (for the NumPy processing example)
