Furnace is a multi-system chiptune tracker and vintage sound chip emulator used for composing and rendering audio. It functions as a music sequencer that mimics legacy hardware, including FM and square wave synthesizers, to create authentic retro sounds. The project distinguishes itself by enabling multi-system chiptune production, allowing users to mix different vintage audio chips and wavetable synthesizers within a single project. It also serves as a module editor compatible with DefleMask project files and provides a headless audio player for streaming modules via a console interface with

eqMac is a system-wide audio equalizer and volume mixer for macOS. It utilizes a virtual audio driver to intercept system output, allowing users to adjust frequency response, boost system volume, and control independent volume levels for different running software applications. The project functions as an audio unit plugin host, integrating third-party plugins into the system audio stream for professional effects. It also includes a local web server that enables remote audio control via HTTP, allowing users to modify audio parameters from a mobile device or other external hardware on the same

Matchering is an audio mastering tool and Python library designed to match the frequency balance and loudness of a target track to a specific reference track. It functions as a reference-based mastering system that aligns a target signal's spectral envelope, RMS, and peak amplitude with those of a chosen reference file. The project utilizes a multi-stage processing pipeline featuring an FFT spectral matching engine to adjust frequency response. It ensures output quality through the use of a brickwall limiter to prevent signal clipping while preserving the original waveform shape. The tool pr

Scribbletune is a JavaScript music composition library, MIDI file generator, text-based patch diagrammer, and Web Audio API sequencer. It enables the definition of rhythms, chords, and melodies using string-based notation for real-time playback in web browsers. The system transforms simple text notation into SVG visual representations of modular synthesizer signal paths. It also converts programmatically composed musical clips and patterns into standard MIDI files for use in external digital audio workstations. Composition capabilities include a character-based rhythmic notation system for p

BespokeSynth is a modular synthesizer environment that combines a node-based audio graph routing system with a live scripting bridge, enabling real-time patching and control without recompilation. Its architecture integrates a granular synthesis engine, FFT-based spectral processing, a MIDI Polyphonic Expression pipeline, and a Euclidean rhythm generator, all within a freeform workspace designed for live experimentation. The project distinguishes itself through its live coding capabilities, allowing Python scripts to create, modify, and control synthesis parameters at runtime, and its plugin

NAudio is a .NET audio library that provides playback, recording, format conversion, and signal processing capabilities for Windows applications. It serves as an audio format converter between common formats like WAV, MP3, AAC, and AIFF using ACM or Media Foundation codecs, and functions as an audio playback and recording API through Windows audio APIs including WaveOut, DirectSound, ASIO, and WASAPI. The library includes an audio stream processor that can mix, trim, loop, fade, resample, and adjust pitch or channel count of audio streams with a floating-point engine. It also provides an audi

Pydub is a Python audio manipulation library and digital audio processor used for editing, slicing, and converting audio files and segments. It serves as a programmatic wrapper for FFmpeg to import and export a wide variety of audio formats.
