Features
- Python Audio Manipulation Libraries - An audio processing library that reads, writes, and transforms audio files with built-in effects and third-party plugin support.
- Audio File Handling - Opens common audio file formats and reads sample data into arrays with automatic decoding.
- Directed Audio Graph Architectures - Organizes audio processing as a directed graph of plugin nodes with flexible routing and mixing.
- Audio Processing - Processes live audio streams through a chain of effects for real-time manipulation.
- Batch Processing - Reads audio files, applies effects, and writes results to disk in common formats automatically.
- Effect Chains - Chains multiple audio effects and plugins into sequential or parallel processing pipelines.
- Guitar-Style and Dynamic Effects - Ships built-in guitar-style, dynamic, spatial, pitch, and lossy compression audio effects.
- Real-Time Effect Processors - Processes live audio streams through effect chains for real-time manipulation of microphone or line input.
- Live Audio Stream Processors - Streams live audio through an effects chain for real-time manipulation of microphone or line input.
- Live Audio Effect Processors - Applies effects to live microphone or line input streams for real-time audio manipulation and monitoring.
- MIDI-Driven Synthesis Platforms - Passes MIDI messages through instrument plugins to generate audio output from note and control data.
- File-Based Effect Processors - Processes audio files through built-in and third-party plugin effects with format I/O.
- MIDI Instrument Processors - Passes MIDI messages through instrument plugins to generate audio output from note and control data.
- MIDI-to-Audio Synthesizers - Passes MIDI messages through instrument plugins to generate audio output from note and control data.
- Third-Party Plugins - Loads VST3 and Audio Unit instrument and effect plugins on supported operating systems.
- Audio Plugin Hosting - Loads and runs third-party VST3 and Audio Unit instrument and effect plugins on major operating systems.
- C++ Plugin Hosting Bridges - Ships a C++ bridge that loads VST3 and Audio Unit plugins and exposes them to Python.
- VST3 and Audio Unit Hosts - Loads and controls third-party VST3 and Audio Unit instrument and effect plugins with parameter access from Python.
- VST3 Plugin Hosts - Loads and controls VST3 instrument and effect plugins for audio processing within Python scripts.
- Training Data Augmentation - Integrates audio effects into data pipelines to augment training audio for model development.
- Audio Resampling Transformations - Changes the sample rate of audio files or streams during processing with constant memory usage.
- Parallel Effect Merging - Merges multiple parallel effect chains by summing their outputs with configurable gain.
- Parallel Effect Chain Combiners - Combines multiple effect chains in parallel and mixes their outputs for layered transformations.
- ML Audio Augmentation Pipelines - Runs audio effects inside data pipelines to augment training data during model development.
- Audio Unit Plugin Hosts - Loads and controls Audio Unit plugins on macOS for audio processing within Python scripts.
- Named Plugin Parameter Controls - Reads and writes plugin parameters using human-readable names and units.
- Audio Loopback Drivers - Captures live audio from system inputs and routes it through the effect graph with sub-millisecond latency.
