Aspen Instruments Black Diamond Probe v1.0.1 VST3 AU WiN MAC

Black Diamond Probe is a free analysis tool that captures the distortion signature of real hardware or software. Send audio through a tube preamp, tape machine, or overdrive pedal while Probe compares input and output to reconstruct the device’s transfer curve. You can then export that curve as a .tfunc file and load it into Black Diamond Distortion to reuse, tweak, or push further. It’s aimed at hobby producers who want to understand how their gear colors sound or build a personal library of gain-stage profiles. For accurate results, the device under test should be memoryless—most distortion, saturation, and waveshaping effects qualify. Compressors, preamps with EQ enabled, and tape-style hysteresis may produce loops or shifting plots, so exported curves should be treated as approximations. Probe runs as VST3 and AU on Windows and macOS, and the .tfunc files work directly in Black Diamond Distortion’s preset browser. It’s a practical way to learn what your favorite gear is actually doing.
