AIDA-X vs Guitarix

AIDA-X is a free AI amp model player for loading and playing music-gear models, primarily for high-fidelity amplifier simulations. Signal chains can combine amp and cabinet models with distortion, drive, fuzz, boost, and EQ. The desktop plugin supports CLAP, LV2, VST2, and VST3, and a standalone version is available. Its cabinet simulator follows the amp model and accepts WAV or FLAC impulse-response files. Controls include input and output meters, bypass, input level, EQ tone controls, and output level. Desktop installers are provided for macOS and Windows, with Linux binary tarballs. The experimental browser version runs in WebAssembly-capable browsers and lets users load their own amp models and cabinet IRs, but it uses preselected guitar loops instead of audio input. The standalone app connects to the system-default audio device and does not offer another input or output selection. Desktop builds are unsigned and may trigger untrusted-developer warnings. AIDA-X is licensed under GPL-3.0-or-later.

Guitarix is free software that acts as a virtual guitar amplifier on Linux through the JACK Audio Connection Kit. Mono sound-card input passes through a main amplifier and rack section, which can be routed separately for stereo output via JACK. The rack contains more than 25 effect modules, including noise gate, flanger, phaser, and auto-wah. LADSPA and LV2 plugins can be added, and Guitarix is also available as an LV2 plugin suite for loading amps and plugins in a digital audio workstation. The project names Ardour and supports connection to Rackarrack or another JACK-aware host. It can process synths and other sound generators as well as guitar. The maker says a properly configured Linux system can process signals in no more than 10 ms. Guitarix is standalone software with an IR loader, licensed under GNU GPL version 2. It is listed for Linux and macOS; source can be built for BSD and MacOSX.
