AIDA-X vs Soundshed Guitar

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.

Soundshed Guitar is a free guitar and bass multi-effects app for Windows, macOS, and Linux. It runs standalone or in a DAW through VST3, AU, or CLAP. Neural Amp Modeler A2 supplies amp tones, with Tone3000 available inside the app. Effects can be arranged in any order, split into parallel paths, connected through graph-based routing, and combined with other plugins. Impulse-response cabinet simulation lets users load and blend their own cabinets. Community presets and tone packs can be browsed, complete setups imported, and preset assets transferred between systems or collaborators. Built-in tools include a tuner, metronome, jam backing tracks, quick riff capture, and a Practice Tool. Version 1.6.0 adds nine effects, fifteen drive pedal models, gapless preset switching, signal-chain undo, and A/B comparison. Minimums include Windows 10/11 x64 with AVX2, macOS 11+, 4GB RAM, and 500MB disk space. Listed audio rates are 44.1–96kHz with latency under 10ms at 48kHz.
