AIDA-X vs Gjalla

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.

Gjalla is a free, open-source guitar amp simulator for black metal and other raw styles. Sognevo, a one-person project making dark-music audio plugins, provides it for Windows, macOS, and Linux as VST3, CLAP, and, on macOS, AU, plus a standalone application. The processing chain includes input trim, noise gate, pedal, preamp, tone stack, power section, presence, cabinet, frost, and output trim. Its pedal offers 90s distortion, HM-2-style chainsaw, and starved-transistor fuzz voicings. Three analytic cabinets are included; WAV or AIFF impulse responses up to two seconds can be loaded, or the cabinet can be disabled for an external loader. Six factory presets, meters, editable knob values, undo and redo, tooltips, and a resizable interface are provided. Host latency is reported as six samples, stated as 0.13 ms at 48 kHz. There is no packaged release yet, so users must build from source or follow GitHub releases. A build requires Git, CMake 3.22 or later, and a C++20 compiler. Gjalla is GPLv3-or-later and has no telemetry, network access, update checks, or accounts.
