Open-source alternatives to Viper4Linux GUI

The advanced drum machine for Linux, macOS, and Windows

Flash AIR sound effects generator. Based on Sfxr.

This is a music generator for use in tiny JavaScript productions (i.e. js13k games). ZzFXM uses a modified version of the super-tiny ZzFX library by Frank Force to generate instruments. The modified version of ZzFX is able create an array of audio data without immediately playing it.

ZzFX is a tiny sound generator designed to produce a wide variety of sound effects with minimal code overhead. It's perfect for games, prototypes, and any web application that needs sound without the bulk of traditional sound files.

Rack is a virtual Eurorack modular synthesizer emulator and a modular synthesis SDK. It provides a digital environment for creating and routing electronic music signals using virtual modules, oscillators, and filters, simulating the behavior of analog hardware through voltage-based signal routing. The system functions as a MIDI and CV converter, translating signals between software and external hardware, and can operate as a VST or industry-standard instrument plugin within digital audio workstations. It also acts as a VST plugin host, embedding external virtual instruments and effects to exp

Ardour is a digital audio workstation, multitrack audio mixer, and MIDI sequencer. It functions as a non-linear audio editor and a plugin host for running third-party effects and instruments. The system provides specialized capabilities for post-production audio scoring through video frame synchronization, as well as live performance sequencing for triggering clips and patterns in real-time. It also supports tactile mixing via control surface mapping and hardware controller configuration. The software covers a broad range of audio production needs, including multitrack recording, MIDI sequen

EasyEffects is a real-time audio processor and system-wide effects manager designed for PipeWire audio streams. It functions as a comprehensive suite for applying filters, equalizers, and limiters to both input and output audio across the entire system. The project distinguishes itself through its use of deep learning for neural network noise suppression and voice isolation, as well as its ability to simulate physical acoustic environments using impulse-response convolution. It includes a sophisticated preset management system that allows users to associate specific audio configurations with

Audacity is a cross-platform digital audio workstation and multi-track audio editor. It serves as a comprehensive suite for capturing live audio input, refining sound files through splicing and effects, and mixing multi-track audio files using a non-destructive waveform interface. The project functions as a VST3 plugin host, providing a software environment to load and execute audio effects and virtual instruments for real-time signal processing. It also includes an audio spectrum analyzer for visualizing frequencies and waveforms to identify specific sonic characteristics. The software cove
