aubio is a collection of tools for music and audio analysis that integrates the C-based aubio library with NumPy. It provides efficient tools for processing audio signals, including:

• Reading audio from media files, videos, and remote streams.
• High-quality phase vocoders, spectral filterbanks, and linear filters.
• Mel-Frequency Cepstrum Coefficients (MFCC) and standard spectral descriptors.
• Note attack (onset) detection.
• Pitch tracking (fundamental frequency estimation).
• Beat detection and tempo tracking.

The package is compatible with both Python 2 and Python 3.

Syphon is a framework for sharing video and still images with other applications in real-time. It consists of three main components:

1. Syphon Servers: Used to make frames available to other applications. You can use either SyphonMetalServer or SyphonOpenGLServer.
2. Syphon Clients: Used to connect to and receive frames from a server. You can use either SyphonMetalClient or SyphonOpenGLClient.
3. Syphon Server Directory: Used to discover available servers on the system via SyphonServerDirectory.

Interoperability: Servers and clients are interoperable between OpenGL and Metal. For example, a Metal client can receive frames from an OpenGL server.

aubio is a library designed to label music and sounds by listening to audio signals and detecting events. It is used for tasks such as segmenting sound files before attacks, pitch detection, beat tapping, and producing MIDI streams from live audio.

Core algorithms and routines include:

• Onset detection methods
• Pitch detection methods
• Tempo tracking and beat detection
• MFCC (mel-frequency cepstrum coefficients)
• FFT and phase vocoder
• Up/down-sampling
• Digital filters (low pass, high pass, etc.)
• Spectral filtering
• Transient/steady-state separation
• Sound file read/write access
• Mathematics utilities for music applications

This directory contains a minimal, vendored subset of Spout2, which is a server-side DirectX 11 sender. It is used by Sonic Pi's Publish Window via Spout feature on Windows.

Unlike the full upstream repository, this subset only includes the SpoutDX (DirectX 11 sender) path. It deliberately omits OpenGL helpers, GL-based wrappers, demos, examples, and the SpoutPanel / SpoutSettings tools.

Syphon is an open source technology for macOS that enables real-time sharing of video and still images between different applications.

This specific repository hosts the Syphon.framework, which is intended for developers who want to integrate Syphon capabilities directly into their own software.

If you are looking for existing plugins for tools like Quartz Composer, Max/Jitter, or FFGL, you should visit the Syphon Implementations repository instead.

aubio is a collection of algorithms and tools designed to label and transform music and sounds. It can process audio by scanning files or listening to live audio signals to detect musical events such as drum hits, note frequencies, or rhythmic tempos.

Key capabilities include:

• Onset Detection: Segmenting sound files before attacks.
• Pitch Detection: Identifying musical notes.
• Tempo & Beat Tracking: Tapping the beat and tracking tempo.
• Signal Processing: FFT, phase vocoder, up/down-sampling, and digital filters (low pass, high pass, etc.).
• Feature Extraction: MFCC (mel-frequency cepstrum coefficients) and transient/steady-state separation.
• MIDI Generation: Producing MIDI streams from live audio.
• File I/O: Sound file read and write access.

The aubio library provides several command line tools for audio analysis and manipulation. These are categorized into tools provided by the Python module and additional tools included with the library.

Python module tools:

• aubio: Used to estimate and extract descriptors from sound files.
• aubiocut: Used to slice sound files at detected onset or beat timestamps.

Additional library tools:

• aubioonset: Outputs timestamps of detected note onsets.
• aubiopitch: Identifies the fundamental frequency (pitch) for each frame of input sound.
• aubiomfcc: Computes Mel-frequency Cepstrum Coefficients (MFCC).
• aubiotrack: Outputs timestamps of detected beats.
• aubionotes: Emits MIDI-like notes containing onset, pitch, and duration.
• aubioquiet: Extracts quiet and loud regions from audio.

The translation effort focuses on two main areas:

• Sonic Pi Qt GUI: The desktop application interface. It contains a limited number of message strings and is relatively easy to translate.
• The Tutorial: A comprehensive, step-by-step guide for new users. This is a large document written in GitHub Markdown, which includes special control character sequences that should be respected during translation.

Note: The Reference documentation is currently not available for translation.

Note for Developers: If you are contributing code and need to understand the internal internationalization (i18n) mechanics, refer to the Translation Workflow instead of this guide.
