Live Audio Mixers and Soundboards

FineTune is a macOS audio management tool designed for directing application audio streams to specific output devices and controlling per-app volume levels. It functions as an audio routing manager and a system utility for device management. The project features a multi-band audio equalizer with headphone response correction and a hardware interface for adjusting external monitor volume levels via the display data channel. It also includes a control interface that allows volume and routing changes to be triggered by external scripts using custom URL schemes. The software covers broader capabilities including dynamic audio routing with multi-device output support, per-application volume balancing, and keyboard shortcut bindings for audio adjustments. It also provides tools for monitoring input levels and managing Bluetooth connections.

This project is a system audio processor and digital signal processing engine designed to enhance system-wide sound volume and clarity. It functions as a high-fidelity sound enhancer and parametric audio equalizer that shapes the sonic profile and timbre of audio across all output devices. The software utilizes a virtual audio device driver to intercept system audio streams at the kernel level, redirecting them through a processing pipeline. This allows for real-time sound processing and low-latency audio filtration to minimize the delay between sound generation and output. The system covers capabilities for multi-band parametric equalization and audio enhancement, enabling the adjustment of specific frequency bands to customize the output for different speakers or headphones.

NoiseTorch is a cross-platform audio processor and real-time noise filter designed to suppress ambient sound from audio streams. It functions as a virtual microphone noise suppressor and routing tool, capturing system audio sources and directing filtered signals into virtual input or output devices. The application uses a recurrent neural network to distinguish between human speech and ambient noise. It provides a virtual denoising microphone that removes background noise from a selected input, alongside tools for filtering audio output streams. The system includes capabilities for audio device management, such as source enumeration and signal routing. It features voice activation tuning with configurable amplitude thresholds and system-level resource limiting to maintain stable, low-latency performance. The software includes mechanisms for managing updates through the verification of cryptographically signed remote archives.

BackgroundMusic is a system-level macOS audio management utility that provides an application volume mixer for independent gain and level adjustments for every running application. It functions as a system audio router and pause controller to manage how sound is handled across the operating system. The project features a virtual audio driver that routes internal system sound to recording software and input devices. It also includes automatic music ducking, which monitors system audio activity to pause music playback when other applications produce sound and resume it once that audio ends. The tool covers broader audio management capabilities including the ability to boost quiet audio sources beyond their default maximum and the capture of internal system sound for use with recording software.

Virtual-Display-Driver is a kernel-level driver for Windows that emulates physical monitors and audio devices. It serves as a virtual monitor emulator, headless server display emulator, and virtual audio device driver to enable extended desktop space and sound routing on systems without physical hardware connections. The project enables the simulation of monitors with custom resolutions, refresh rates, and identification profiles, including support for High Dynamic Range output. It also provides software-defined audio interfaces to simulate virtual microphones and speakers. The software covers broad capability areas including headless server operation, remote desktop stream enhancement, and virtual audio routing. Additionally, it includes utilities for overlay screen capture and picture-in-picture streaming of specific windows or screens.

QuickRecorder is a screen recording software designed for capturing desktops, application windows, and system audio. It functions as a multi-device video recorder and tutorial capture tool, synchronizing video feeds from a computer and connected mobile devices into a single stream. The system distinguishes itself through an alpha-channel video exporter that produces recordings with transparent backgrounds. It also includes a presenter overlay system that renders a floating camera feed over screen captures and a specialized tutorial toolset that provides mouse movement highlighting and a magnification lens. The application covers a broad range of capture capabilities, including system audio recording via loopback methods and the ability to record specific window regions. It supports the production of product demonstration videos and instructional content by combining multiple source streams into a synchronized recording.

LMMS is a digital audio workstation and MIDI sequencer designed for composing, arranging, and mixing music. It functions as a comprehensive production environment that integrates a MIDI sequencer, a sample-based synthesizer, and an audio mixing console. The project distinguishes itself through a versatile synthesis engine that includes additive synthesis, wavetable generation, and emulations of vintage hardware such as NES audio and FM chips. It also serves as a VST plugin host, allowing for the integration of third-party virtual instruments and audio effects via a standardized interface. Beyond synthesis, the platform covers wide-ranging capabilities in audio mixing and signal processing, including the use of effect chains, sidechain compression, and a modulation matrix. It provides tools for MIDI sequencing through a piano roll and step sequencer, as well as hardware integration for mapping physical MIDI controllers to software parameters. Project states, instrument settings, and automation are saved and restored using XML-based serialization.

Yabridge is a compatibility bridge that allows Windows audio plugins to run within Linux digital audio workstations. It utilizes a Wine-based wrapper to translate audio processing and plugin calls from Windows plugins to Linux hosts, supporting both VST2 and VST3 standards. The system manages the execution of both 32-bit and 64-bit Windows plugins on Linux. It includes specialized mechanisms to handle window scaling, input focus, and the transfer of data through cross-environment drag-and-drop between native Linux applications and Windows plugins. The project provides tools for environment isolation through prefix management and reduces system overhead by hosting multiple plugin instances within shared processes. It also includes a configuration override system to correct display bugs and activity logging to diagnose plugin behavior.

This project is a professional live video production suite designed for capturing, encoding, and broadcasting high-quality media. At its core, it features a real-time media processing engine that utilizes hardware acceleration to composite multiple audio and video sources with minimal latency. The application provides a centralized studio interface for managing complex scene transitions, layering visual sources through a hierarchical scene-graph engine, and streaming content to multiple platforms simultaneously. The software is built on a cross-platform abstraction layer that ensures consistent performance across major desktop operating systems. Its modular architecture allows for extensive customization, enabling users to extend core functionality through third-party plugins or lightweight scripting integrations. This design supports specialized production workflows by allowing the connection of external tools and the automation of routine tasks. Beyond its primary production capabilities, the project includes tools for managing custom user interface themes and maintaining configuration consistency. The codebase follows strict development standards to support ongoing community collaboration and the integration of diverse, high-performance extensions.
